Mutation of SCARECROW-LIKE28 or CYTOKININ OXIDASE3/5 significantly reduces rosette branching in Arabidopsis, with both mutants showing altered flowering time.
- Why it matters: Understanding how plant hormones interact to regulate shoot branching is crucial for improving crop architecture and productivity, yet the mechanisms remain unclear.
- What they did: Researchers used Arabidopsis mutant lines, including scl28 and ckx3 ckx5, and conducted transcriptomic, functional, and genetic studies to explore their roles in branching regulation.
- The result: The mutants exhibited increased expression of SL biosynthesis genes, and genetic data indicated that SCL28 and CKX3/5 influence rosette branching through the SL signaling pathway, independently affecting flowering.
