Analysis of the CHS Gene Family Reveals Its Functional Responses to Hormones, Salinity, and Drought Stress in Moso Bamboo (Phyllostachys edulis).

ABSTRACT: Chalcone synthase (CHS), the first key structural enzyme in the flavonoid biosynthesis pathway, plays a crucial role in regulating plant responses to abiotic stresses and hormone signaling. However, its molecular functions remain largely unknown in Phyllostachys edulis, which is one of the most economically and ecologically important bamboo species and the most widely distributed one in China. This study identified 17 CHS genes in Phyllostachys edulis and classified them into seven subgroups, showing a closer evolutionary relationship to CHS genes from rice. Further analysis of PeCHS genes across nine scaffolds revealed that most expansion occurred through tandem duplications. Collinearity analysis indicated strong evolutionary conservation among CHS</
