Abstract

The accumulation of phenylalanine-derived phenolic compounds is a well-known element of a plant's defense in response to pathogen attack. Phenylalanine, as well as the other two aromatic amino acids, tyrosine and tryptophan, is synthesized by way of the shikimate pathway. The first seven steps of the shikimate pathway (the prechorismate pathway) are common for the biosynthesis of all three aromatic amino acids. We have studied transcript levels of six genes--i.e., two 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase genes, one shikimate kinase gene, one 5-enolpyruvylshikimate 3-phosphate synthase gene, and two chorismate synthase genes--corresponding to four steps of the prechorismate pathway, in cultured tomato cells exposed to fungal elicitors. The abundance of transcripts specific for some of these genes increased 10- to 20-fold within 6 h after elicitor treatment, as did the abundance of phenylalanine ammonialyase-specific transcripts and the synthesis of ethylene. Interestingly, transcript accumulation occurred more rapidly for shikimate kinase than for the enzymes preceding or following it in the prechorismate pathway. Neither the inhibition of ethylene biosynthesis by aminoethoxyvinylglycine nor inhibition of phenyla...Continue Reading

Biosynthetic Transformations

Biosyntheic transformtions are multi-step, enzyme-catalyzed processes where substrates are converted into more complex products in living organisms. Simple compounds are modified, converted into other compounds, or joined together to form macromolecules. Discover the latest research on biosynthetic transformations here.
