Recently, scientists from Chongqing University provided new insights into the complex regulatory network of phytohormones that regulate fruit ripening in tomato. They introduced multi-gene interference (RNAi) vectors to silence the expression of target ABA receptors and screen for receptors that mediate ABA signaling during the regulation of fruit ripening. SlRCAR9, SlRCAR12, SlRCAR11, and SlRCAR13 were identified as crucial ABA receptors, as fruit ripening time was prolonged when these receptors were co-silenced.
