Overview

Research explores how MYB regulators affect pigmentation in plants, indicating evolutionary pathways.

Key Points

  • The study investigates how MYB transcription factors evolved to regulate different branches of the flavonoid pathway in plants.
  • Expressed MYB regulators in Petunia hybrida
  • Assessed anthocyanin accumulation
  • Used yeast two-hybrid assays to study protein interactions
  • Different MYBs induced overlapping but distinct sets of target genes
  • Functional differences among MYBs from various species were observed
  • Divergence in bHLH and WD40 protein binding capacity among MYBs suggests evolutionary specialization
