Structural Biology of Cytochrome P450 Monooxygenases in Arabidopsis Thaliana Phenylpropanoid Pathway
… rate-limiting hydroxylation steps in the phenylpropanoid pathway. Homology modeling studies of the P450-substrate interactions in these four P450s have indicated that substrates bind in similar orientations and locations in all four P450s. De novo models of several bacterial and mammalian …

Paralogous genes in Arabidopsis thaliana contribute to diversified phenylpropanoid metabolism
… in specialized metabolism. Using the Arabidopsis phenylpropanoid pathway as a model, in this thesis I describe two cases where neofunctionalization and subfunctionalization of duplicated genes contributed to metabolite diversification.^ The phenylpropanoid pathway intersects with primary …

Investigating Extreme Lifestyles Through Mangrove Transcriptomics
… , which are at major regulatpry points in the phenylpropanoid pathway. I have identified one DFR, two CHS, and ten PAL genes in R. mangle . Differential expression patterns within a family as well as co-expression patterns across families were identified in different tissues indicating possible …

MOLECULAR APPROACHES TO ANALYZE HORIZONTAL RESISTANCE AMONG PLANT SPECIES (MAIZE, SOYBEAN, AND ARABIDOPSIS) TO SYNTENIC FUSARIAL PATHOGENS (F. GRAMINEARUM AND F. VIRGULIFORME)
… concentrations. A set of putative resistance pathways involved in responding to the pathogen infection in A. thaliana was identified. Functional analyses of the orthologs of the responding genes between soybean and A. thaliana showed that the resistance responses had both common elements in …

KINETICS, REGULATION AND PURIFICATION OF L-PHENYLALANINE AMMONIA-LYASE FROM GERMINATING LETTUCE SEEDS (PHENYLPROPANOIDS, ENZYME, ALPHA-AMINOXY - BETA-PHENYLPROPIONIC ACID)
… of PAL by various substrate analogues and phenylpropanoid compounds was studied. Substrate analogues like D-phenylalanine, p-fluorophenylalanine, (beta)-phenyllactic acid and tryptophan were found to inhibit PAL competitively whereas tyrosine did not show any inhibition of enzyme activity. …

Structural studies on the biosynthesis and biological functions of natural products
… include the dissecting of the biosynthesis pathways of these compounds and elucidating the biological processes affected by these compounds. These studies would facilitate the production of potential drugs through biosynthesis or semi-biosynthesis, and provide valuable guidance in …

Variation in peach fruit susceptibility to Monilinia laxa and gene expression
… of those genes encoding for the enzymes of the phenylpropanoid pathway (phenylalanine ammonia lyase (PAL), chalcone synthase (CHS), cinnamate 4-hydroxylase (C4H), leucoanthocyanidine reductase (LAR), hydroxycinnamoyl CoA quinate hydroxycinnamoyl transferase (HQT) and of the jasmonate pathway, …

GRAPEVINE-ASSOCIATED MICROORGANISMS AS BIOCONTROL AGENTS AGAINST THE PROLIFERATION OF PATHOGENIC FUNGI
… and B. cinerea. Gene expression analysis of the phenylpropanoid pathway indicated increased expression of the resveratrol transporter gene in grapevine leaves inoculated with both B. cinerea and B. velezensis, suggesting enhanced plant defensive responses. In conclusion, B. velezensis ED163 is a …

Identification and molecular characterisation of elicitor-priming for resistance in tomato against <i>Botrytis cinerea</i>
… induction of the lipid/fatty acid metabolism and phenylpropanoid pathway; and 5) a strong repression of <i>B. cinerea </i>PGs, <i>BcSOD</i>, hexokinase and novel virulence factor uracil phosphoribosyltransferase (<i>BcUPRT</i>).Transcriptome analysis helped to the identification of two tomato …

Potential for selection of new peanut genotypes with enhanced polyphenol antioxidant content
… using LC-MS/MS and propose phenolic biosynthesis pathways, and 4) to investigate the feasibility of developing a simple nanoparticle-based test for the rapid and low-cost phenotyping of antioxidant capacity for rapid selection of antioxidant capacity in breeding and segregating populations. The …

Elucidation of the Function of Dihydrochalcones in Apple
… for phloridzin in plant growth. The biosynthetic pathway leading to DHC formation has been proposed in apple, and some steps have been characterised recently. DHC pathway diverts from the main phenylpropanoid pathway most probably from 4-coumaroyl-CoA by the action of a yet unknown reductase that …

Subcellular localisation and functional analysis of UVR8, a UV-B specific signalling component in Arabidopsis
… factors HY5 and HYH, enzymes involved in the phenylpropanoid pathway, antioxidant and stress proteins (Brown et al., 2005). UVR8 shows 30% sequence identity to the human regulator of chromatin condensation (RCC1) but differs both in activity and function. The phenotype of uvr8 mutant plants is …
