Integrative chloroplast omics in citrus: computational insights into genomic structural adaptation and phylogenetic relationships from 35 species.

ABSTRACT: The chloroplast genome serves as a valuable tool for plant phylogenetic studies due to its conserved structure and slow evolutionary rate. Despite the economic importance of the genus Citrus, comprehensive comparative analyses of chloroplast genomes across multiple species remain limited. As one of the ancestors of Citrus, Citrus medica L. serves as a key representative in studies of the origin and evolution of the genus. In this study, we conducted a comprehensive comparative analysis of chloroplast genomes from 35 Citrus species and their close relatives, with C. medica as a focal species, to investigate structural variation, codon usage patterns, and phylogenetic relationships. All genomes exhibited a typical quadripartite structure, ranging from 159 to 161 k
