Expression And Functional Characterization Of Avocado Dgat1 And Pdat1 In Arabidopsis And Camelina, Josphat Kiunga
Expression And Functional Characterization Of Avocado Dgat1 And Pdat1 In Arabidopsis And Camelina, Josphat Kiunga
Electronic Theses and Dissertations
The study is aimed to determine the role of avocado DGAT1 and PDAT1 in seed oil synthesis. Triacylglycerol (TAG) has a nutritional and industrial value and is essential for plant growth. DGAT1 and PDAT1 catalyze the final step of TAG Assembly. We hypothesized that both PaPDAT1 and PaDGAT1, although predominantly expressed in non-seed tissues, could contribute to oil accumulation in seeds. Agrobacterium transformants with PaPDAT1 and PaDGAT1 cloned in pCAMBIA were generated to test this. Subsequently, the Agrobacterium-mediated transformation of Arabidopsis mutant lines and camelina was carried out by floral dipping. The T1 camelina seeds …
Functional Role Of Ppal And Potential For Moss In Industrial Applications., Susana Perez Martinez
Functional Role Of Ppal And Potential For Moss In Industrial Applications., Susana Perez Martinez
Electronic Theses and Dissertations
This dissertation is an examination and characterization of the functional roles of PPAL. PROTEIN PRENYLTRANSFERASE ALPHA SUBUNIT-LIKE (PPAL) is a recently discovered gene. PPAL homologs are present in all plants and many animals, where its function is largely unknown. It is possible that PPAL could participate in prenylation processes since it shares similarity to the α subunits of known prenylation enzymes. Prenylation is a post-translational modification of proteins that involves the addition of a lipid moiety to proteins to facilitate membrane targeting and association and promote protein-protein interactions. Prenylation has important roles in plant growth and development, including …

Identification And Characterization Of Genes Involved In Metabolism Of N5 Monoene Precursors To N5 Anacardic Acids In The Trichomes Of Pelargonium X Hortorum., Richa A. Singhal
Electronic Theses and Dissertations
Unusual monoenoic fatty acids (UMFA’s) and specialized metabolites called anacardic acids (AnAc) are produced in glandular trichomes of Pelargonium ´ hortorum (geranium). The UMFA’s, 16:1∆11 and 18:1∆13 are precursors for the synthesis of unsaturated AnAc 22:1n5and 24:1n5 that contribute to pest resistance in geraniums. UMFAs and their derived AnAc metabolites not only provide a useful biological marker that differentiates the biosynthetic pathway for unusual mononenes from the common fatty acids (i.e. stearic, palmitic, oleic, linoleic and linolenic) but also have industrial, medical and agricultural applications. Fatty acid biosynthesis enzymes like acyl carrier proteins (ACPs); thioesterases (TEs) and β-ketoacyl-ACP …
