Functional Descriptions:

  • PYL9 is involved in the regulation of ABA signaling during tomato fruit ripening.
  • We reveal the role of SlPYL9, a tomato pyrabactin resistance (PYR)/pyrobactin resistance-like (PYL)/regulatory component of ABA receptors (RCAR) protein, as a positive regulator of ABA signaling and fruit ripening.
  • SlPYL9-OE/RNAi plants showed a typical ABA hyper-/hypo-sensitive phenotype in terms of seed germination, primary root growth, and response to drought.
  • Fruit ripening was significantly accelerated in SlPYL9-OE by 5–7 d as a result of increased endogenous ABA accumulation and advanced release of ethylene compared with the wild-type.
  • In the SlPYL9-RNAi lines, fruit ripening was delayed, mesocarp thickness was enhanced, and the petals did not abscise as timely as the WT, resulting in conical / oblong and gourd-shaped fruit. These results suggest that SlPYL9 is involved in ABA signaling, thereby playing a role in the regulation of flower abscission and fruit ripening in tomato.
