FaMYB10

Gene Details:

This insertion introduced a predicted premature termination codon, which suggested the loss of intact FaMYB10 protein playing a critical role in the loss of red colour in white octoploid strawberry.
These results confirmed that FaMYB10 genes control anthocyanin and colour production in fruit of octoploid strawberry and that the loss of the functional FaMYB10 protein is critical to the loss of fruit colour in white octoploid strawberry.
ABA is a signal molecule that promotes FaMYB10 and FaMYB1 expressions, and FaMYB10 or FaMYB1 interacts with bHLH and WD40 to form a putative canonical MBW activation complex, which activates transcription of structural genes and causes anthocyanin accumulation.
The R2R3 MYBs control fruit colour, and FaMYB10-2 leads to coloration loss in the fruits of WS.
Light and ABA independently regulated anthocyanin biosynthesis via activation of FaMYB10 expression. FaMYB10 accelerated anthocyanin synthesis of pelargonidin 3-glucoside and cyanidin 3-glucoside during strawberry fruit ripening.
