Pega-pinto (Boerhavia diffusa L.) and bredo (Trianthema portulacastrum L.) are common weeds that occur in areas of feijão-caupi (Vigna unguiculata L.), in Rio Grande do Norte and Ceará. When infected by M. phaseolina, this culture causes gray stem rot, drastically reducing yield. Therefore, the present work aimed to verify the virulence of Macrophomina spp. obtained from pega-pinto and bredo. The experiments were conducted in Vegetation House of the Universidade Federal Rural do Semi-Árido (UFERSA), in Mossoró-RN. Two trials were carried out to evaluate the severity of 100 isolates of Macrophomina, not first to posteriori 50 isolates in the pega-pinto roots and, in the second, 50 isolates from roots of bredo. In both assays, a Macrophomina Feijão-caupi isolate was used. The experimental design was completely randomized, with five replicates. All 50 isolates of Macrophomina spp. caused gray stem rot symptoms in caupi and 64% these isolate showed a similar severity to the caupi isolate. In the bredo, 90% of the isolates caused the disease, however none of them presented severity equal to the caused by caupi isolates / O fungo Macrophomina phaseolina é um fitopatógeno polífago que ataca mais de 600 espécies de plantas, incluindo espécies daninhas que podem ser suas hospedeiras. Pega-pinto (Boerhavia difusa L.) e bredo (Trianthema portulacastrum L.) são espécies daninhas que ocorrem com frequência em áreas de produção do feijão-caupi (Vigna unguiculata L.), no Rio Grande do Norte e Ceará. Quando infectada por M. phaseolina, esta cultura causa a podridão cinzenta do caule, reduzindo drasticamente a produção. Sendo assim, o presente trabalho teve como objetivo verificar a severidade de isolados de Macrophomina spp. obtidos de pega-pinto e bredo. Os experimentos foram conduzidos em Casa de Vegetação da Universidade Federal Rural do Semi-Árido (UFERSA), no município de Mossoró-RN. Foram realizados dois ensaios para avaliar a severidade de 100 isolados de Macrophomina. No primeiro, foram avaliados 50 isolados provenientes das raízes de pega-pinto e, no segundo, 50 isolados oriundos de raízes de bredo. Em ambos os ensaios, utilizou-se um isolado de Macrophomina de feijão-caupi. O delineamento utilizado nos experimentos foi o inteiramente casualizado, com cinco repetições. Todos os 50 isolados de Macrophomina spp. oriundos de pega-pinto causaram sintomas de podridão cinzenta do caule nas plantas de feijão-caupi e 64% destes isolados apresentaram incidência igual ao isolado oriundo de caupi, entretanto apenas um isolado apresentou severidade igual ao isolado do caupi. Para o bredo, 90% dos isolados causaram a doença, porém, nenhum deles tendo apresentado severidade igual à ocasionada pelo isolado de feijão-caupi / 2017-12-19

This study aimed to evaluate productive characteristics, gross income and Efficient Use of Land (UET) of the castor bean plants with cowpea bean in monocrop and intercropped with castor bean and maize monocrop and intercrop under different planting arrangements in a regime rainfed semiarid region in the central interior of Ceará. Two experiments were conducted in Farm Lavoura Seca, owned by the Federal University of Ceará in Quixadá / Ceará, Brazil, between April and August 2011. The experimental delineate for both experiments was a randomized block with six treatments and four repetitions. Populations desired been obtained varying the number of plants within the row, with alternate single rows. The plots were composed by four rows of each crop, which was used as a useful plots just the two central rows. The treatments consisted of monoculture castor bean, cowpea and maize, by using 10,000, 40,000 and 40,000 plants ha-1 respectively and other consortiums: (castor bean 10,000 + 40,000 cowpea or maize); (castor bean 5,000 + 40,000 cowpea or maize); (castor bean 10,000 + 20,000 cowpea or maize); (castor bean 5,000 + 20,000 cowpea or maize) plants ha-1. The higher productivity of castor bean was obtained using 10,000 plants ha-1 both consortia with cowpea as an in monocrop, independent of population of beans. Since when consortia with maize, the factor that most affect the yield was the increase of maize population, in detriment of reducing the population of the castor bean. The highest yields of cowpea were found in the monoculture and did not differ statistically from consortiums (castor bean 5,000 +40,000 cowpea) and (castor bean 5,000 +20,000 cowpea) plants ha-1. All of the arrangements between castor bean and cowpea were efficient in land use, have dominated the castor bean in all consortia, being more competitive and compromising the quality of the same. / O consórcio consiste no cultivo simultâneo de duas ou mais culturas na mesma área, como estratégia para reduzir o risco da atividade diante da irregularidade climática muito frequente nas regiões semiáridas. Este trabalho objetivou avaliar características agronômicas e Uso Eficiente da Terra (UET) de plantas de mamona com feijão caupi em monocultivo e consorciadas e mamona com milho em monocultivo e consorciados em diferentes arranjos de plantio em regime de sequeiro na região semiárida do sertão central cearense. Foram conduzidos dois experimentos na Fazenda Lavoura Seca, pertencente à Universidade Federal do Ceará em Quixadá/Ceará, Brasil, entre os meses de abril e agosto de 2011. O delineamento utilizado para ambos os experimentos foi em blocos ao acaso com seis tratamentos e quatro repetições. As populações desejadas foram obtidas variando o número de plantas dentro da fileira, sendo fileiras simples alternadas. As parcelas foram compostas por quatro fileiras de cada cultura, na qual usou-se como parcela útil apenas as duas fileiras centrais. Os tratamentos consistiram de monocultivo de mamona, caupi e milho, usando 10.000, 40.000 e 40.000 plantas ha-1 respectivamente e dos demais consórcios: (mamona 10.000 + 40.000 caupi ou milho); (mamona 5.000 + 40.000 caupi ou milho); (mamona 10.000 + 20.000 caupi ou milho); (mamona 5.000 + 20.000 caupi ou milho) plantas ha-1. A maior produtividade de mamona foi obtida usando-se 10.000 plantas ha-1 tanto consorciada como em monocultivo com caupi, independente da população de feijão. Já quando consorciada com o milho, o fator que mais interferiu no rendimento foi o aumento da população de milho, em detrimento da redução da população da mamoneira. As mais elevadas produtividades de feijão caupi foram constatadas no monocultivo e não diferiu estatisticamente dos consórcios (mamona 5.000+40.000 caupi) e (mamona 5.000+20.000 caupi) plantas ha-1. A mamona mesmo na máxima população não competiu significativamente em nível de comprometer o rendimento do cereal. Todos os arranjos entre mamona e feijão caupi foram eficientes no uso da terra, já o milho dominou a mamoneira em todos os consórcios, sendo mais competitivo e comprometendo o rendimento da mesma.

myo-Inositol synthesis and catabolism are crucial in many multicellular eukaryotes for production of phosphatidylinositol and inositol phosphate signaling molecules. myo-inositol monophosphatase (IMP) is a major enzyme required for the synthesis of myo-inositol and breakdown of inositol (1,4,5)-trisphosphate (InsP3), a potent second messenger involved in many biological activities. Arabidopsis contains a single canonical IMP gene, which was previously shown in our lab to encode a bifuntional enzyme with both IMP and L-galactose 1-phosphatase activity. Analysis of metabolite levels in imp mutants showed only slight modifications with less myo-inositol and ascorbate accumulation in these mutants. This result suggests the presence of other functional IMP enzymes in plants. Two other genes in Arabidopsis encode chloroplast proteins, which we have classified as IMP-like (IMPL), because of their greater homology to the prokaryotic IMPs such as the SuhB, and CysQ proteins. Prokaryotic IMP enzymes are known to dephosphorylate D-Inositol 1-P (D-Ins 1-P) and other substrates in vitro, however their in vivo substrates are not characterized. A recent study revealed the ability of IMPL2 to complement a bacterial histidinol 1-phosphate phosphatase mutant defective in histidine synthesis, which suggested an important role for IMPL2 in amino acid synthesis. The research presented here focuses on the characterization of IMPL functional roles in plant growth and development. To accomplish this I performed kinetic comparisons of the Arabidopsis recombinant IMPL1 and IMPL2 enzymes with various inositol phosphate substrates and with L-histidinol 1-phosphate, respectively. The data supports that IMPL2 gene encodes an active histidinol 1-phosphate phosphatase enzyme in contrast to the IMPL1 enzyme which has the ability to hydrolyze D-Ins 1-P substrate and may be involved in the recycling of inositol from the second messenger, InsP3. Analysis of metabolite levels in impl2 mutant plants reveals that impl2 mutant growth is impacted by alterations in the histidine biosynthesis pathway. Together these data solidify the catalytic role of IMPL2 in histidine synthesis in plants and highlight its importance in plant growth and development. / Ph. D.
