Insights into the plastome evolution and phylogenetic relationships of Lepidium (Brassicaceae).

ABSTRACT:

Background

Lepidium represents one of the most species-rich genera in the Brassicaceae, encompassing numerous taxa with excellent medicinal value. Although the plastome architecture of Brassicaceae has been extensively characterized, its evolutionary dynamics within Lepidium remain poorly understood. Besides, the intrageneric taxonomy has long been problematic, primarily due to subtle morphological differences or overlapping morphological characteristics. Here, 15 Lepidium plastomes (11 newly sequenced and 4 published) were subject to comparative genomic and phylogenetic analyses to investigate plastome evolution and phylogenetic relationships.

Results

The total length of the 11 newly sequenced Lepidium plastomes varied from 153,803 bp to 154,997 bp, with 111-112 unique gene
