A natural small molecule 2-amino-3-methylhexanoic acid enhances tomato thermotolerance via stabilization of the key mediator SlGAD4.
Plant resistance inducers (PRIs) are bioactive compounds that trigger protective responses, offering promise for reducing stress-induced yield losses in agriculture. The natural PRI (2S, 3S)-2-amino-3-methylhexanoic acid (AMHA) markedly improves tomato (Solanum lycopersicum) tolerance to high temperature (HT), but its...
