Overview

Research uncovers a regulatory module that balances oil and protein levels in Brassica napus seeds, indicating a crucial pathway for crop improvement.

Key Points

  • The study aims to identify key regulators that balance oil and protein levels in Brassica napus seeds during storage reserve accumulation.
  • Investigated the roles of BnaC03.TFL1 and BnaC09.TFL1 in seed biosynthesis pathways.
  • Analyzed the interaction between BnaC03.TFL1 and BnJAM3 proteins.
  • Assessed the expression of BnSWEETs transporters in relation to carbon flux in seeds.
  • BnaC03.TFL1 significantly enhances soluble sugar and oil biosynthesis while repressing protein deposition.
  • BnaC03.TFL1 physically interacts with BnJAM3 proteins, promoting similar effects.
  • The BnTFL1-BnJAM3-BnSWEETs module directs carbon flow towards fatty acid biosynthesis, optimizing oil over protein production.
