Comparative analysis of 18 chloroplast genomes reveals genomic diversity and evolutionary dynamics in subtribe Malaxidinae (Orchidaceae).

ABSTRACT:

Background

The subtribe Malaxidinae encompasses diverse species, many of which possess remarkable medicinal properties that have been employed in traditional Chinese medicine for centuries. Although recent advancements have improved our understanding of the backbone phylogeny of Malaxidinae, clarifying the complex intergeneric relationships remains challenging, largely owing to limited genomic data. To address this gap and further investigate the genetic diversity and evolutionary patterns within this subtribe, we sequenced and assembled complete chloroplast (cp.) genomes from sixteen Malaxidinae species. These newly acquired genomic resources, combined with two previously published cp. genomes from closely related species, were incorporated into a comprehensive comparative genomic
