Gene Details:

  • Gene ID:
  • Gene Symbol: CaMYB31
  • Gene Name: MYB transcription factor Cap1
  • Genome:
  • Species: Capsicum annuum

Functional Descriptions:

  • Natural variations in the MYB transcription factor MYB31 determine the evolution of extremely pungent peppers.
  • The Cap1/Pun3 locus encodes the Solanaceae-specific MYB transcription factor MYB31.
  • The capsaicinoid content depends on MYB31 expression. Natural variations in the MYB31 promoter increase MYB31 expression in C. chinense via the binding of the placenta-specific expression of transcriptional activator WRKY9 and augmentation of CBG expression, which promotes capsaicinoid biosynthesis.
  • Variations in the promoter of MYB31 in C. chinense species result in the formation of a W-box, which leads the promoter to bind a WRKY TF and, consequently, to enhance MYB31 expression and determine the evolution of extreme pungency in Capsicum species.
  • MYB31 is a transcriptional activator and positively regulates CAP and DhCAP biosynthesis in peppe.
