Comparative chloroplast genomics of Teucrium species reveals genome evolution, phylogenetic relationships, and candidate molecular markers.

ABSTRACT: The genus Teucrium (Lamiaceae) comprises approximately 250 species with significant medicinal and ecological importance. Despite extensive phytochemical studies, molecular data, particularly on chloroplast (cp.) genomes, remain limited for many species, especially those native to Iran. In this study, we sequenced and analyzed the complete cp. genomes of three Iranian Teucrium species, T. chamaedrys, T. flavum, and T. polium, to investigate genome structure, variation, and phylogenetic relationships within the genus. Using high-throughput sequencing, we assembled and annotated the cp. genomes, revealing typical quadripartite structures with sizes ranging from 149,913 bp to 150,026 bp. Comparative genomic analyses, including IR boundary shifts, codon usage, repeat elements, and nucleotide di
