Enhanced brassinosteroid signaling reduces waterlogging tolerance in Nardostachys jatamansi seedlings by decreasing root lignification and increasing radial oxygen loss.
- Why it matters: Understanding how phytohormone signaling affects waterlogging response is crucial for improving plant resilience to abiotic stress, especially in sensitive alpine species like N. jatamansi.
- What they did: Applying 24-epibrassinolide to seedlings altered gene expression related to lignin biosynthesis, promoted root elongation, and increased radial oxygen loss, with a survival rate decrease of about 12.5%.
- The result: Reduced root lignification and increased oxygen loss impair hypoxia adaptation, revealing that brassinosteroid signaling limits lignin synthesis, which compromises waterlogging tolerance in these plants.
