LcGST4 Functions in Anthocyanin Accumulation in Lychee
January 13, 2016| |
Glutathione S-transferases (GSTs) have been defined as detoxification enzymes for their ability to recognize reactive electrophilic molecules as well as endogenous secondary metabolites. Anthocyanin is one of the few substrates of GSTs for accumulation. The gene encoding a GST protein involved in anthocyanin accumulation from lychee (Litchi chinensis Sonn.) has not been reported.
South China Agricultural University's Bing Hu led researchers in studying LcGST4, an anthocyanin-related GST. Analysis revealed that the expression pattern of LcGST4 was strongly correlated with anthocyanin accumulation in lychee. ABA- and light-responsive elements were found in the LcGST4 promoter, which proves that the expression of LcGST4 was induced by both ABA and light.
Further analysis revealed that the expression of LcGST4 was activated by LcMYB1, a key R2R3-MYB transcription factor that regulates anthocyanin biosynthesis in lychee.
