The link between phosphate starvation-triggered anthocyanin biosynthesis and jasmonate-driven regulation in tomato.

Phosphate starvation triggers a JA-mediated anthocyanin biosynthesis pathway in tomato, involving a PHR/PHL module and MYC2-dependent transcriptional activation.

• Why it matters: Understanding this link is crucial because it reveals how plants adapt to nutrient deficiencies by modulating secondary metabolism, which impacts crop quality and nutritional value.
• What they did: The study reviews recent findings on the PSR-jasmonate-anthocyanin axis in tomato, highlighting the roles of PHR/PHL transcription factors, JA signaling components, and MBW complex regulators, supported by a proposed model.
• The result: This work advances knowledge of nutrient-responsive pigmentation regulation, enabling targeted breeding strategies to improve phosphorus efficiency and enhance tomato nutritional traits.
