Phylogenomic insights from the complete chloroplast genome of Berchemiella wilsonii var. pubipetiolata H. Qian (Rhamnaceae) from Zhejiang

Berchemiella wilsonii var. pubipetiolata H. Qian, a member of the Rhamnaceae family, is endemic to mountainous regions in two eastern Chinese provinces. Here, we present the first assembly of its chloroplast (cp) genome, which exhibits a typical quadripartite structure, spans 160,317 bp long and has a 37.20% GC content. Genome annotation identified 131 genes, including 84 messenger RNA (mRNA) genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA genes. Phylogenetic analysis confirms its close relation to B. wilsonii, thereby providing valuable genomic resources for conservation efforts and evolutionary studies of East Asian Berchemiella species.
