Drought upregulates SlZAT5 and SlJIG in tomato, increasing ABA accumulation and drought tolerance, with SlZAT5 transrepression of SlCYP707A3 required for repression.
- Why it matters: Water deficiency limits tomato growth and yield, and ABA-mediated drought responses depend on balancing ABA synthesis and catabolism.
- What they did: Tomato plants were drought-treated and analyzed for SlZAT5/SlJIG expression; IP-MS tested SlZAT5–SlJIG interaction, and promoter binding plus repression assays assessed SlCYP707A3 regulation.
- The result: Overexpression of SlZAT5 or SlJIG improved drought tolerance, while knockout of either reduced it and the double mutant showed a further decline, supporting a SlZAT5–SlJIG module controlling ABA homeostasis.
