Plants have evolved a variety of constitutive and induced chemical defense mechanisms against biotic stress. Emission of volatile compounds from plants facilitates interactions with both beneficial and pathogenic organisms. However, knowledge of the chemical defense in roots is still limited. In this study, we have examined the root-specific biosynthesis and function of volatile terpenes in the model plant Arabidopsis. When infected with the root rot pathogen Pythium irregulare, Arabidopsis roots release the acyclic C11-homoterpene (E)-4,8-dimethylnona-1,3,7-triene (DMNT), which is a common constituent of volatile blends emitted from insect-damaged foliage. We have identified a single cytochrome P450 monooxygenase of the CYP705 family that catalyzes a root-specific oxidative degradation of the C30-triterpene precursor arabidiol thereby causing the release of DMNT and a C19-degradation product named arabidonol. We found that DMNT shows inhibitory effects on P. irregulare mycelium growth and oospore germination in vitro, and that DMNT biosynthetic mutant plants were more susceptible to P. irregulare infection. We provide evidence based on genome synteny and phylogenetic analysis that the arabidiol biosynthetic gene cluster containing the arabidiol synthase (ABDS) and CYP705A1 genes possibly emerged via local gene duplication followed by de novo neofunctionalization. Together, our studies demonstrate differences and plasticity in the metabolic organization and function of terpenes in roots in comparison to aboveground plant tissues. Additionally, we demonstrated that the arabidiol cleavage product, arabidonol, is further modified by yet unknown enzymatic reactions into three products, which are found in root exudates. We suggested a pathway for their biosynthesis based on precursor feeding experiments and NMR analysis. Although DMNT biosynthetic genes are clustered on chromosome 4 along with several potential modification genes, we did not find a possible role of these genes in the derivatization of arabidonol. Preliminary experimental results using genetic and biochemical approaches for identifying genes involved in the modification steps are also presented. In summary, this study demonstrates an alternative route for volatile terpene formation belowground different from aboveground plant tissues via triterpene degradation and provides evidence for an unexplored triterpene catabolism pathway in Arabidopsis. / Ph.

Nesta pesquisa, também observaremos as semelhanças e diferenças nos corpora de traduções jurídicas e juramentadas, no que concerne ao uso desses termos e padrões lexicais, assim como apontaremos aqueles que são mais frequentemente empregados em documentos do tipo contrato social e estatuto social. A investigação baseia-se na abordagem interdisciplinar dos Estudos da Tradução Baseados em Corpus, da Linguística de Corpus, da Fraseologia, de modo mais específico das colocações, das colocações especializadas e das unidades fraseológicas especializadas. A Terminologia, por meio de seus pressupostos teóricos, também traz sua contribuição para a pesquisa, assim como os trabalhos sobre a tradução juramentada. Uma das motivações que delineia este estudo reside no fato de a tradução juramentada ser considerada de grande relevância nas relações comerciais, sociais e jurídicas entre as nações. Para realizar este estudo, compilamos um corpus de estudo (CE1) constituído por contratos sociais e estatutos sociais traduzidos no modo juramentado, nas direções tradutórias inglês português e português inglês, extraídos de Livros de Registro de Traduções, pertencentes a tradutores juramentados credenciados pela Junta Comercial de dois Estados brasileiros; e um corpus de estudo (CE2) formado por documentos de mesma natureza traduzidos sem o processo de juramentação, nas mesmas direções tradutórias. Além destes corpora, construímos dois corpora comparáveis, formados pelos referidos documentos originalmente escritos em português e em inglês. Os resultados desta pesquisa mostraram várias semelhanças, no tocante aos termos empregados em documentos traduzidos... / This investigation aims at carrying out a study on terms, collocations and extended specialized collocations present in articles of incorporation/articles of organization/articles of association and bylaws that represent our research corpora. We will also observe similarities and differences in sworn and legal translation corpora, which concerns the use of such terms and lexical patterns, as well as point out the ones which are more frequently used in the focused documents. This research derives its theoretical and methodological sources from Corpus-Based Translation Studies, Corpus Linguistics, Phraseology, more specifically from collocations, specialized collocations and specialized phraseological units (SPUs). Terminology, from its theoretical standpoint, also offers its contribution to this study, as well as essays on sworn translation. One of the aspects that motivates this study is the fact that sworn translation is considered to be of great relevance to commercial, social and legal relations among nations. To conduct this research, we compiled a study corpus (CE1) composed of articles of incorporation/articles of organization/articles of association and bylaws submitted to the process of sworn translation in the English Portuguese and Portuguese English directions, excerpted from the Books of Sworn Translation Records, made available by five Brazilian sworn translators, duly sworn by the Board of Trade of two Brazilian States; a study corpus (CE2) made up of documents of the same nature not submitted to the process of sworn translation, in the same translation directions. Besides these corpora, we also built two comparable corpora formed by the referred documents originally written in Portuguese and in English. The results obtained in this research showed some similarities which refer to the terms used in documents submitted to the process of sworn translation...

[ES] Los incendios forestales son un tema de flamante actualidad en la cuenca mediterránea, han pasado de ser un elemento tradicional de gestión agroforestal a devenir la principal amenaza para la supervivencia de los bosques como consecuencia del cambio climático y del abandono de las zonas rurales. Esta tesis aborda el estudio de la terminología catalana de este campo con tres objetivos: compilarla, caracterizarla y ofrecer una aplicación terminológica adaptada a las necesidades profesionales. Desde el punto de vista teórico, se enmarca en la Teoría Comunicativa de la Terminología (Cabré, 1999) y se fundamenta en las investigaciones sobre los lenguajes de especialidad, la terminología y el trabajo terminológico, que tienen como objeto de estudio principal los términos y como producto prototípico los diccionarios. Desde el punto de vista empírico, acomete una investigación terminográfica sistemática monolingüe con equivalencias siguiendo una metodología ampliamente contrastada en terminología catalana. Primero, se analizan las necesidades terminológicas del personal especialista en incendios forestales y su contexto profesional. Segundo, se elabora un corpus de textos de la especialidad, a partir del cual se realiza la extracción semiautomatizada de los términos mediante la estación de trabajo terminológico Terminus, atendiendo a un árbol de campo previamente preestablecido. A continuación, se configura un fichero terminológico de más de un millar de términos seleccionados del campo de estudio y se completa con definiciones, subcampos, contextos, equivalencias y otras informaciones. Tercero, se analiza el listado de términos obtenido desde un punto de vista formal, semántico, neológico y contrastivo, para establecer los rasgos singulares. Finalmente, se desarrolla una propuesta de diccionario terminológico de incendios forestales catalán-castellano-inglés dirigida al personal experto. / [CA] Els incendis forestals són un tema de flamant actualitat a la conca mediterrània, han passat de ser un element tradicional de gestió agroforestal a esdevenir la principal amenaça per a la supervivència dels boscos com a conseqüència del canvi climàtic i de l'abandonament de les zones rurals.

They have ceased to be a traditional element of agroforest management to become the main threat for the survival of the forests because of climatic change and abandonment of rural areas. This thesis addresses the study of the Catalan terminology of this field with three main aims: compile it, characterize it and offer a terminological application adapted to the needs of the specialists. From the theoretical point of view, it fits in the framework of the Communicative Theory of Terminology (Cabré, 1999) and is based on the studies on specialized languages, terminology and the terminological work, that have the terms themselves as the main object of study, and the dictionaries as a main product. From an empirical point of view, it accomplished a terminographic monolingual systematic research with equivalences following a widely contrasted methodology in Catalan terminology. First, the terminological needs of the specialists in forest fires and their professional context are analyzed. Second, a corpus of specialized texts is created, from which a semiautomated extraction of the terms by means of the terminological workstation Terminus is done, attending to a preestablished field tree. Following this, a terminological file is compiled, with more than a thousand terms selected by field and completed with definitions, subfields, contexts, equivalences and other information. Third, the list of terms obtained is analyzed from a formal, semantic, neologistic and contrasted point of view, in order to establish their distinctive traits. Finally, a proposal for a terminological forest fires dictionary in Catalan-Spanish-English addressed to experts is presented. / Gil Puig, A. (2022). La terminologia catalana dels incendis forestals.

S.O. / Le présent mémoire vise à faire l’étude des procédés d’explicitation dans les traductions anglais-français de textes spécialisés de l’environnement. Plus précisément, notre but est d’identifier l'éventail de ces procédés d'explicitation, de faire leur analyse, de les classifier et de proposer quelques pistes quant aux causes possibles de l’explicitation dans la traduction. Nous présentons d’abord quelques travaux antérieurs qui ont porté sur l’explicitation dans des corpus de langue générale et dans des corpus spécialisés. Notre recherche a ceci de particulier qu’elle porte sur l’explicitation dans un corpus spécialisé, plus particulièrement dans des textes du domaine de l’environnement. L’explicitation est peu étudiée dans les textes spécialisés et, à notre connaissance, aucune étude n’a porté sur l’explicitation dans des textes environnementaux. Pour notre recherche, nous avons élaboré d’abord un corpus de textes anglais-français portant sur l’environnement. Notre corpus a ensuite été aligné au moyen de l’aligneur LogiTerm Pro. Cet aligneur nous permet de créer un corpus aligné qui est utile pour observer les manifestations d’explicitation. Les stratégies d'explicitation identifiées et classées par Pápai (2004) ont servi de base à notre propre classement. Nous avons découvert que les procédés d’explicitation se produisent à cinq niveaux : des relations logiques et visuelles, lexical et grammatical, syntaxiques I et II, textuel et extralinguistique. Le nombre total de procédés d’explicitation que nous avons identifiés est de 13. Le plus grand nombre de cas d’explicitations (445) se situe au niveau lexical et grammatical. Parmi les cas d’explicitations au niveau lexical et grammatical, le remplissage d’ellipses sémantiques présente le nombre le plus élevé de cas (186) dans notre corpus spécialisé. L’explicitation au niveau syntaxique I s’observe dans 173 cas; l’explicitation au niveau des relations logiques et visuelles s’observe dans 101 cas; l’explication au niveau syntaxique II a été relevée dans 50 cas. Enfin, l’explication se produit au niveau textuel et extralinguistique dans 37 cas. Après avoir observé notre corpus et d’après les résultats obtenus, nous avons pu constater que le nombre et la variété d’explicitations étaient élevés dans les traductions anglais-français de textes spécialisés environnementaux. / This work aims to study the explicitation strategies in English-French translations of specialized texts related to the field of environment. More specifically, our goal is to identify the range of these explicitation strategies, analyze and classify them. We will also offer some explanations of possible causes of explicitation in translation. First, we present some previous work on explicitation in general language corpora and in specialized corpora. A particularity of our own research is that it focuses on explicitation in a specialized corpus, more specifically in texts in the field of environment. Explicitation has seldom been studied in specialized texts and, to our knowledge, no study focused on explicitation in environmental texts. For our research, we compiled a corpus of English-French environment texts. Our corpus was then aligned using the aligner LogiTerm Pro. This aligner allows us to create aligned corpora that are useful to observe the linguistic instances of explicitation. The explicitation strategies identified and classified by Pápai (2004) have served as the basis for our own analysis. We found that the explicitation strategies occur at five levels: logical and visual relations, lexical and grammatical, syntactic I and II, textual and extra-linguistic. The total number of explicitation strategies that we have identified is 13. The largest number of explicitation instances (445) occurs on the lexical and grammatical level. Among explicitation instances on the lexical and grammatical level, filling semantic ellipses present the highest number of instances (186) in our specialized corpus. Explicitation on the syntactic level I was observed in 173 instances; explicitation on the logical and visual relations level in 101 instances; explicitation on the syntactic level II was found in 50 instances. Finally, explicitation occurred on the textual and extra-linguistic level in 37 instances. After observing our corpus and according to the results obtained, we have found that the number and variety of instances of explicitation are high in English-French translations of specialized texts in the field of the environment.

Nosso estudo abrange dois temas gerais: por um lado, a contribuição dos nomes de cores para a variação denominativa em terminologia a partir de uma perspectiva interlinguística; por outro, a descrição de tais variantes em uma obra lexicográfica especializada e multilíngue. A fim de delimitar a nossa pesquisa, concentramo-nos na análise de dois subdomínios da Biologia: a Botânica, especificamente as Angiospermas (monocotiledôneas e eudicotiledôneas), e a Zoologia, exclusivamente os Vertebrados (peixes, anfíbios, répteis, aves e mamíferos). Dessa forma, visamos, em primeiro lugar, ampliar o Dicionário Onomasiológico de Expressões Cromáticas da Fauna e Flora por meio da inserção em sua microestrutura dos correspondentes das palavras-entrada em línguas inglesa e italiana. Seguindo a metodologia proposta em nosso Mestrado (MARTINS, 2013), utilizamos o Corpus Web para a busca e validação dos correspondentes. Em segundo, uma vez verificada a existência de correspondentes para cada entrada, realizamos sua análise estrutural, observando o papel desses itens para a divulgação dos conceitos da Fauna e da Flora em outras culturas. Em terceiro, examinamos as possíveis causas que atuam na formação de tais unidades e que propiciam ou não a escolha do item cor nas línguas em estudo, isto é, português, inglês e italiano. Por último, ainda em relação à obra lexicográfica, propomos formular a metodologia mais adequada para a implementação de uma plataforma on-line que contribuirá para minimizar as divergências terminológicas nessa área, para a normatização de conceitos e para o estabelecimento da comunicação entre culturas. Enfatizamos que o nosso interesse é motivado pelo papel ativo dos nomes de cores na expansão do léxico e a investigação dessa fatia lexical é uma forma de evidenciar o uso dos nomes de cores para a difusão da terminologia da Fauna e da Flora. Finalmente, visamos contribuir qualitativamente, tanto no aspecto teórico (por meio das reflexões apresentadas) quanto no metodológico, para o âmbito das pesquisas que se limitam ao estudo do léxico, bem como para o conjunto das obras lexicográficas produzidas no Brasil. / The present thesis has as its object of study the terminology of Fauna and Flora composed by color names. Hence, it deals with two major themes: on one hand, the contribution of color names to the denominative variation in Terminology from a interlinguistic perspective; on the other, the description of such variants in a multilingual and specialized lexicographical work. In order to delimit our research, we concentrate our analysis on two subdomains of Biology: Botany, specifically the Angiosperms (monocotyledons and dicotyledons), and Zoology, specifically the Vertebrates (fish, amphibians, reptiles, birds and mammals). In this manner, it aims, firstly, to extend the Onomasiological Dictionary of Chromatic Phrases of Fauna and Flora by inserting in the microstructure the equivalents of the entries in English and Italian languages. Following the methodology proposed in a prior research (MARTINS, 2013), we use the Corpus Web to collect and validate the equivalents. Secondly, once checked the existence of equivalents for each entry, it intends to realize their structural analysis, observing the role of these denominative variants to the propagation of Fauna and Flora concepts in other cultures. Thirdly, examining the probable causes that actuate in the formation of such units and that propitiate or not the choice of the color name in the languages in study, i.e., Portuguese, English and Italian. Finally, still regarding the lexicographical work, we propose to formulate an appropriate methodology for the implementation of an on-line platform that will contribute to minimize terminological variances in this area, to concepts normalization, as well as to the communication among cultures. We would like to emphasize that our interest is motivated by the active role of color names in the expansion of the lexicon and the study of this vocabulary demonstrates the importance of color names to the diffusion of Fauna and Flora terminology. To sum up, we expect to contribute qualitatively, as in the theoretical aspect (by means of the reflections presented in the following pages) as in the methodological aspect, to the range of the lexical studies, as well as to the set of lexicographical works produced in Brazil. / FAPESP: 2013/09232-1

O objetivo desta pesquisa, de delineamento quase-experimental, foi verificar a influência de um Programa de Iniciação ao Tênis (PIT) com duas abordagens, Clássica (AC) e de Contexto Motivacional para a Maestria (AM), no desempenho de habilidades motoras fundamentais (HMF), especializadas do Tênis (HMET) especializadas do Tênis no jogo (HETJ) e na percepção de competência (PC) de crianças em situação de risco. A amostra desta pesquisa foi não probabilística, intencional, composta por 61 crianças (29 meninas e 32 meninos), com idades de 6 a 12 anos (M = 9,4), sendo 30 crianças da AC e 31 crianças da AM. Para as avaliações das crianças foram utilizados o Test of Gross Motor Development-2 (TGMD-2) (ULRICH, 2000); o Instrumento de Avaliação das Habilidades Motoras Especializadas do Tênis, o Instrumento de Avaliação de Habilidades Especializadas do Tênis no Jogo e a escala The Self-Perception Profile for Children (HARTER, 1985). O PIT foi desenvolvido em 26 semanas, implementando, para a AM os pressupostos da estrutura TARGET e do Sport Education Model e para a AC os modelos clássicos de aprendizagem do Tênis. General Linear Model com medidas repetidas no fator tempo foi conduzido para avaliar os efeitos do PIT no desempenho motor e nos níveis de PC, bem como, a influência de faixa etária e gênero. Teste de Wilcoxon foi utilizado para a comparação intra-grupo e teste de Mann-Whitney para a comparação inter-grupo (no jogo quanto à categorização). Análise de variância com medidas repetidas no fator tempo, delta e significância do delta por meio de One Way ANOVA foram utilizadas para avaliar o impacto da intervenção. Os resultados indicaram que 1) crianças do PIT demonstraram mudanças significantes (p < 0,01) nas habilidades de locomoção (HL), sendo que as crianças da AM revelaram escores significativamente (p = 0,034) superiores quando comparadas com a AC ao final da intervenção; 2) todas as crianças evidenciaram mudanças significantes nas habilidades de controle de objeto (HCO) da pré para a pósintervenção (p < 0,01); 3) não houve interação da faixa etária nas HL (p = 0,885) e nas HCO (p = 0,940) e do gênero nas HL (p = 0,791) e nas HCO (p = 0,723); 4) mudanças positivas e significantes (p < 0,01) nas HMET para todas as crianças; 5) interação não significante da faixa etária (p = 0,519) e do gênero (p = 0,24) nas HMET; 6) interação não significante da faixa etária (p = 0,523) e do gênero (p = 0,117) nas HETJ quanto à freqüência; 7) quanto à categorização das HETJ, resultados evidenciaram mudanças positivas para as crianças do PIT ao longo da intervenção, representando 62,5% das atitudes demonstradas no jogo; 8) crianças mais velhas da AC apresentaram mudanças significantes (p < 0,05) da pré para a pós-intervenção em duas categorias de comportamento, enquanto que, crianças mais velhas da AM em cinco (p < 0,05); 9) quanto ao gênero, não houve interação significante (p = 0,50) nas HETJ na categorização das atitudes; 10) quanto à PC, todas as crianças apresentaram mudanças significantes da pré para a pósintervenção (p < 0,01);11) não houve interação significante para a faixa etária (p = 0,096) e gênero (0,465) nas percepções de competência. A implementação de um Programa de Iniciação ao Tênis, baseado em propostas metodológicas eficazes e condizentes com as necessidades reais dos participantes, promove ganhos motores, sociais e emocionais que efetivam a participação das crianças no esporte e na atividade física e contribuem com o seu desenvolvimento. / The purpose of the present study, with a quasi-experimental design, was to verify the influence of a Beginning Tennis Program (BTP) with two approaches – the Classical approach (CA) and the Mastery Motivational Climate approach (MA) – on the development of fundamental motor skills (FMS), specialized tennis motor skills (STMS), specialized tennis motor skills in play (STMSP), and on perceived competence (PC) of children in risky situation. The sample was not probabilistic, intentional, and composed of 61 children (29 girls and 32 boys), aged 6-12 yr. (M = 9.4). Thirty children were submitted to the CA and 31 to the MA. The children were assessed using the Test of Gross Motor Development-2 (TGMD-2) (ULRICH, 2000), the Instrument for Assessing Specialized Tennis Motor Skills, the Instrument for Assessing Specialized Tennis Motor Skills in Play, and The Self-Perception Profile for Children (HARTER, 1985). The BTP was carried out in 26 weeks and implemented for MA the assumptions of the TARGET structure and the Sport Education Model, and for CA the classical models for tennis learning. General Linear Model with repeated measures on the time factor was conducted to assess the BTP effects on motor development and on PC levels, as well as the influence of age group and gender. 7) concerning STMSP categorization, children in BTP demonstrated positive changes over the intervention, representing 62.5% of the attitudes adopted in the play; 8) older children of CA showed significant changes (p < 0.05) from pre- to post-intervention in two behavior categories, whereas older children of MA showed significant changes in five (p < 0.05); 9) concerning gender, there was no significant interaction (p = 0.50) in STMSP in attitude categorization; 10) all children showed significant changes in PC from pre- to post-intervention (p < 0.01); 11) there was no significant interaction of age group (p = 0.096) and gender (0.465) in PC. The implementation of a Beginning Tennis Program based on effective methodological proposals that are suitable for the participants’ real needs fosters motor, social, and emotional gains that reinforce the children engagement in sports and physical activity, and favour their development.
