The complete chloroplast genome of Suaeda physophora Pall. (Chenopodiaceae)

Abstract

Suaeda physophora Pall. (Chenopodiaceae) is a leaf succulent shrub species with potential usefulness as fodder for the desert animal. However, the phylogeny of S. physophora is lacking. Here, we sequenced and assembled a complete chloroplast genome of S. physophora and further reconstructed the phylogeny of Chenopodiaceae. The chloroplast genome of S. physophora is 151,104 bp in length, consisting of an 18,597 bp small single-copy (SSC), an 82,845 bp large single-copy (LSC), and a pair of 24,831 bp inverted repeat (IR) regions. The genome encodes 131 genes, including 87 protein-coding genes, 36 tRNA genes, and eight rRNA genes. Phylogenetic analysis revealed that the genus Suaeda forms a monophyletic taxon, and S. physophora is closely related to S. eltonica. Chloroplast genome and phylogenetic studies provided an essential foundation for the conservation of S. physophora.
