The complete chloroplast genome and phylogenetic analysis of Sida szechuensis matsuda (Malvaceae)

Sida szechuensis Matsuda is an economically and medicinally important plant. Here, we report the first chloroplast (cp) genome of the genus Sida (S. szechuensis). The complete cp genome is 159,878 bp in length with an overall GC content of 36.9% and consists of a large single copy region (LSC, 89,426 bp), a small single copy region (SSC, 114,715 bp), and a pair of inverted repeat regions (IRa and IRb, 25,288 bp). The genome encodes 111 unique genes, including 78 protein-coding genes, 29 tRNA genes, 4 rRNA genes, and 1 pseudogene. Phylogenetic analysis constructed using the maximum likelihood (ML) method showed that Sida was closely related to Malvastrum and Malva.
