Abstract

The complete chloroplast (cp) genome of Mitreola yangchunensis was sequenced and assembled for the first time. The genome is 154,665 bp in length, containing a large single-copy (LSC) region of 85,351 bp, a small single-copy region (SSC) of 18,218 bp and a pair of inverted repeats (IRs) of 25,548 bp. It contains 113 unique genes, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. The overall GC content is 37.9%, while the corresponding values of LSC, SSC, and IR regions are 35.9, 32.0, and 43.4%, respectively. Phylogenetic analyses using complete cp genomes showed that M. yangchunensis is most closely related to Mitrasacme pygmaea in Loganiaceae, and Gelsemiaceae and Loganiaceae form a single cluster with high support value.

Keywords: Complete chloroplast genome; Gentianales; Mitreola yangchunensis.
