Complete chloroplast genome sequence of Pachystachys lutea Nees: genome structure, adaptive evolution, and phylogenetic relationships.

ABSTRACT:

Background

Pachystachys lutea Nees is a typical species of the family Acanthaceae, native to tropical South America. As an evergreen shrub, it has found extensive application in landscape greening due to its unique ornamental value. However, there are currently no phylogenetic and genetic studies on the chloroplast (cp.) genome of P. lutea.

Results

This study characterized the cp. genome of P. lutea using high-throughput sequencing technology and analyzed its structural features and phylogenetic position using bioinformatics methods. The results indicated that the cp. genome had a high degree of conservation in gene structure and gene content, with a typical quadripartite structure. Its total length is 151,574 bp and the total GC content is 38.18%. A total of 132 genes were
