Characterization of three novel genes encoding postulated peptides of the IDA family, and their possible function in plant defense in Arabidopsis thaliana

Hornslien, Karina Stensland January 2011 (has links)
IDL6 and IDL7 are postulated peptides of the INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) peptide family in the model organism Arabidopsis thaliana. The genes encoding the postulated peptides, IDL6 and IDL7, were investigated to potentially elucidate the function of the peptides and the possible relations to plant defense and stress tolerance in A. thaliana. A phenotypic characterization study of single and double knockout mutant lines, and over-expression lines of IDL6 and IDL7 was conducted to potentially find a phenotype linked to the genes by analyzing deviations in growth and development, compared to wild type (Wt) A. thaliana. Over-expression lines showed a tendency to have a higher amount of individuals reaching defined growth stages in seedling development, but this could not be concluded to be a phenotype linked to IDL6 or IDL7.The genes have been shown to be highly up-regulated in response to several different stress treatments, both abiotic and biotic in silico data. Several different transgenic lines of A. thaliana were subjected to different types of stress treatments to potentially verify the in silico data. Knockout lines, double knockout lines, over-expression lines and promoter:GUS lines of IDL6 and IDL7 were treated with abiotic stress factors (NaCl, mannitol, UV-B light, H2O2 and paraquat) and biotic stress factors (aphids, Pseudomonas syringae and flagellin22) to investigate differences in tolerance, gene expression and promoter activity in the respective transgenic lines and Wt A. thaliana.No absolute phenotype was detected in experiments related to stress tolerance, and great variations in promoter activity using promoter:GUS lines were observed. However, double knockout mutants of idl6 and idl7 showed a small trend to tolerate NaCl better than Wt A. thaliana and other transgenic lines. The great variation in GUS expression from GUS assay lead to a thorough screening and expression analyses of promoter:GUS lines. Results presented in this work, indicate that expression of the IDL6 and IDL7 genes may be subjected to extensive post transcriptional regulation through mRNA degradation, possibly governed by stress related environmental signals. A novel member of the IDA peptide family, IDL8, was also analyzed. Segregation analyses of knock out lines were conducted and they were genotyped to verify that mutant lines of idl8 were real knockouts. Results presented here show that one of the idl8 mutant lines had the T-DNA inserted to the promoter region of the gene and is postulated to be a real knockout. However, further expression analyses should be conducted to verify that the gene is not transcribed. Over-expression lines of IDL8 were successfully constructed through recombinant DNA technology and by T-DNA insertion using Agrobacterium tumefaciens.

Characterization of the Cytochrome p450 Family in the unique Diatom Seminavis robusta

Strøm Midthun, Elise January 2012 (has links)
This thesis describes the cytochrome p450 superfamily in the pennate diatom Seminavis robusta. This diatom has a benthic way of life and can adhere to surfaces, and is a new candidate model organism representing the pennate diatoms. The genome of S. robusta is currently being sequenced and is characterized. This revealed that the genome of S. robusta contains 68 genes encoding CYPs, an unusually high number compared to other related organisms. Several unique families and subfamilies were discovered, but also known families from both plants and animals. This reflects the diversity of factors that may have contributed to the evolution of these genes in diatoms, and possibly how a benthic lifestyle may drive this process.Both bioinformatical tools and transcriptional analysis have been used to characterize and explore this superfamily. An experimental study was performed by cultivating S. robusta at different conditions, including normal temperature and light, lower temperature and a day/night cycle. This confirmed some of the CYPs’ involvement in light-/dark-responses, as well as some responses that seemed coupled to temperature.As part of the study, a comparison was made between two software programs used for analyzing gene expression data. This concluded that replacing the software currently used with a new software program with more possibilities will be beneficial for ensuring a higher quality assurance when publishing RT-qPCR data, as well as one step closer publishing according to the MIQE-guidelines.

Srovnání cloud BI řešení a faktory ovlivňující jejich nasazení / Analysis of cloud BI solutions and factors affecting their implementation

Černý, Richard January 2013 (has links)
The combination of Cloud Computing and Business Intelligence (BI) gives many advantages, however the classic deployment model is still in many cases preferred. Both models differ in many aspects and are suitable for various organizations. The thesis looks at these aspects and analyzes the differences that cloud computing brings to the Business Intelligence. Aims of the thesis are to compare both models according the architectural, security, user and financial aspects, influencing of the cloud computing on the implementation of BI and presenting some practical examples of BI solution. To achieve the aims the author uses a literature review, electronic sources and own analysis. Based on the identified impact of the cloud factor the author extends the reference model Management of Business Informatics (MBI).
