Plastome comparison and phylogenomics of Chinese endemic Schnabelia (Lamiaceae): insights into plastome evolution and species divergence.

ABSTRACT:

Background

Schnabelia species, herbaceous perennial plants within the Lamiaceae family, possess medicinal value and are endemic to China. While previous studies have focused on morphological classification, molecular systematics, and medicinal components, there has been limited research on phylogenomics. To reveal their plastid genome characteristics and phylogenetic relationships, we sequenced and assembled the plastomes of all five Schnabelia species (S. oligophylla, S. tetrodonta, S. nepetifolia, S. terniflora, S. aureoglandulosa), conducted comparative genomic analyses, and constructed a phylogenetic tree incorporating closely related taxa in subfamily Ajugoideae, as well as conducting divergence time estimation.

Results

Plastome size of the five species ranged from 155,
