LITERATURE
accumulation of endogenous resveratrol and stilbene synthase mRNA occurrs rapidly and significantly in response to UV-C irradiation. Applying resveratrol before UV-C irradiation mitigates rusty spots and wilting of peanut leaves, and inhibition of resveratrol by applying 3,4-methylenedioxycinnamic acid worsens UV-C damage
cultures expressing plant oncogene rolB of Agrobacterium rhizogenes show an 1.3- to 3.8fold increase in expression of phenylalanine ammonia-lyase and stilbene synthase, resulting in increased resveratrol production
-
R2R3-MYB-type transcription factors MYB14 and MYB15 strongly coexpress with STS genes, both in leaf tissues under biotic and abiotic stress and in the skin and seed of healthy developing berries during maturation. MYB14 and MYB15 specifically activate the promoters of STS genes, and the ectopic expression of MYB15 in grapevine hairy roots results in increased STS expression and in the accumulation of glycosylated stilbenes in planta
significant accumulation of STS mRNA and new STS protein during early heat acclimation
STS is induced by UV-C irradiation. UV-induced STS occurs in palisade tissues of grape leaves and phloem tissues of grape leaf veins, stems, and roots
the promoter shows elevated responsiveness to salicylic acid and to the pathogen-associated molecular pattern (PAMP) flg22, equal induction of both alleles by jasmonic acid, and a lack of response to the elicitor Harpin. The elevated salicylic acid response of the STS promoter depends on calcium influx, oxidative burst by RboH, mitogen-activated protein kinase signalling, and jasmonic acid synthesis
-
transcription levels of STS5, 6, 7, 8, and 10 genes considerably increase under 0.1, 0.25, and 0.5 mM cinnamic acid
-
UV-C irradiation intensely stimulates STS in grape leaves, increasing the resveratrol level
UV-C irradiation leads to intense accumulation of enzyme and its product resveratrol
UV-induced increase in stilbene synthase amount is developmental stage-dependent and time course-dependent, with response of stiblene synthase being postponed concomitantly with the progressive development of berry
