Overview

Isolation of the BnaGSK3/DCA1 mutant shows that it affects auxin biosynthesis, indicating a role in branch angle control.

Key Points

  • The BnaGSK3-BnaIDD16 module negatively regulates branch angle in Brassica napus.
  • Gain-of-function mutations of BnaGSK3 are linked to smaller branch angles and slightly shorter plant height.
  • Map-based cloning identified BnaGSK3 as a key regulator involved in BR signaling for auxin activation.
  • Natural haplotypes have variations in the BnaGSK3 promoter that impact plant architecture traits, suggesting potential for breeding.
