Complete chloroplast genome sequence of Micranthes melanocentra (Saxifragaceae)

The phylogenetic relationships among Micranthes taxa remain unclear due to their diversification. Here, we report the complete chloroplast genome of Micranthes melanocentra obtained using high-throughput sequencing technology to provide genomic information for phylogenetic analyses. The plastome is 155,317 bp, with a large single-copy region (LSC) of 86,784 bp, a small single-copy region (SSC) of 18,007 bp, and a pair of 25,263 bp inverted repeat regions (IRs). The genome contains 132 genes, including 86 protein-coding genes, 37 tRNA genes, 8 rRNA genes, and 1 pseudogene. The GC content of the plastome is 37.9%; corresponding values in the LSC, SSC, and IR regions are 36.1%, 31.9%, and 43.3%, respectively. The phylogenetic tree supports the separation of Micranthes from Saxifraga s.l.
