Reports multi-omics analysis linking carotenoid metabolism and ABA signaling to natural leaf abscission in sugarcane, highlighting candidate genetic targets.
Key Takeaways
- Multi-omics identified 37 differentially accumulated metabolites and 3,109 differentially expressed genes
- Zeaxanthin epoxidase (ZEP) and β-carotene hydroxylase (BCH) were upregulated in abscission-prone cultivars
- Increased ABA precursors and correlated ZEP/BCH expression indicate activated carotenoid-derived ABA biosynthesis
