Identification of Chalcone Synthase Genes and Their Responses to Salt and Cold Stress in <i>Poncirus trifoliata</i>.

ABSTRACT: Chalcone Synthase (CHS) plays a vital role in flavonoid synthesis, influencing plant growth, development, and responses to both biotic and abiotic stress. In this study, 11 CHS genes were identified in Poncirus trifoliata using bioinformatics methods, with their distribution across five chromosomes and unassigned contigs. Each gene contains 2-3 exons and 3-8 conserved motifs. In silico prediction suggested that the PtrCHS proteins are localized in the cytoplasm. PtrCHS9 and PtrCHS11 share identical protein tertiary structures. Phylogenetic analysis classified the CHS family members into four subgroups. Synteny analysis revealed one set of collinear gene pairs within Poncirus trifoliata. Between Poncirus trifoliata and Arabidopsis thaliana, two sets
