How plants balance growth and stress adaptation is a long‐standing topic in plant biology. Abscisic acid (ABA) induces the expression of the stress‐responsive Asparagine Rich Protein (NRP), which promotes the vacuolar degradation of PP6 phosphatase FyPP3, releasing ABI5 transcription factor to initiate transcription. Whether NRP is required for growth remains unknown.

Limiting water loss by reducing transpiration helps plants survive when water is limited. Under drought stress, abscisic acid (ABA)‐mediated gene expression and anion channel activation regulate stomatal closure and stress responses. ABA‐induced actin reorganization also affects stomatal closure, but the underlying molecular mechanism remains unclear.
In this study, we discovered that under nonstress...
