GhSQS1-mediated squalene accumulation coordinates cotton development and stress resilience.
Squalene is a high-value triterpenoid. It is increasingly recognized for its regulatory roles in plant signaling. However, the functions of squalene in cotton remain unexplored. Here, we show that exogenous squalene can promote cotton developmental traits (root elongation and ovule development) and identify GhSQS1 as t...
