Gene Details:

• Gene ID:
• Gene Symbol: FaMYB1
• Gene Name: transcription factor MYB1
• Genome:
• Species: Fragaria ananassa

Functional Descriptions:

• The strawberry transcription factor FaMYB1 inhibits the biosynthesis of proanthocyanidins in Lotus corniculatus leaves.
• The data suggest that FaMYB1 may counter-balance the activity of the endogenous transcriptional MYB–bHLH–WD40 (MBW) complex promoting proanthocyanidin biosynthesis via the catechin and epicatechin branches and that FaMYB1 does not interfere with the expression levels of a resident R2R3MYB activator of PAs.
• This action was dose dependent and specific in that it reduced the accumulation of PA polymers only in leaf tissues. Such depletion was heritable, and the analysis of other flavonoid end-products indicated that FaMYB1-mediated interventions were restricted to proanthocyanidin biosynthesis.
• The FaMYB1 gene from strawberry was used, which has been reported to interact with bHLH partners and repress the anthocyanidin pathway in tobacco.
