Pangenome-wide identification and expression analysis of the chalcone synthase (CHS) gene family in five yellowhorn spp.
Twenty-seven chalcone synthase (CHS) genes were identified across five yellowhorn genomes, with four core genes conserved in all and two dispensable genes varying among genomes.
- Why it matters: Understanding the CHS gene family is crucial because it plays a key role in flavonoid biosynthesis, plant development, and stress responses, yet remains uncharacterized in yellowhorn, a species valued for its resilience.
- What they did: Researchers conducted a pangenome-wide analysis, including phylogenetic, structural, and expression profiling, identifying gene duplication events and stress-responsive expression patterns in five yellowhorn genomes.
- The result: The study revealed candidate CHS genes, such as Xg11_CHS1 and Xg11_CHS3, that are upregulated under cold and drought stress, providing targets for enhancing stress tolerance and flavonoid production in yellowhorn.
