Characteristics of plastid genomes in the Saururaceae and their phylogenomic implications.

ABSTRACT:

Background

Saururaceae are an ancient family within Piperales, comprising seven perennial herbs grouped into four relict genera: Anemopsis, Gymnotheca, Houttuynia, and Saururus; distributed primarily in East Asia (Gymnotheca, Houttuynia, and S. chinensis) and North America (Anemopsis and S. cernuus). Despite the limited number of species, phylogenetic relationships remain inconsistent across non-molecular data, nuclear genes, and chloroplast genes.

Results

Here, we report for the first time the plastid genomes of G. involucrata and H. emeiensis and provide an additional plastid genome of S. chinensis, enabling a comprehensive analysis of the plastid genome evolution in Saururaceae. All seven plastomes exhibit the typical Quadripartite structure, ranging from 160,226 to 161,5
