Increased SAUR30 abundance during cold stress suppresses TIP1;1 water channel activity and expression in Arabidopsis, and disrupting their interaction restores root elongation and cellular water content.
- Why it matters: Cold stress threatens plant productivity by altering transport and cellular processes, yet how SAUR family members coordinate transcriptional and post-translational control of water movement remains unclear.
- What they did: Using yeast two-hybrid and split-ubiquitin screens, ratio BiFC, Xenopus oocyte swelling assays, and Arabidopsis loss-of-function/overexpression lines, the study tested SAUR30–TIP1;1 regulation under cold stress.
- The result: Cold stress-linked SAUR30–TIP1;1 interaction downregulates TIP1;1 abundance and suppresses its intrinsic water channel activity, and saur30 knockout or a non-binding SAUR30 chimera restores root elongation and cellular water content under cold stress.
