Complete chloroplast genome sequence of Chrysosplenium ramosum and Chrysosplenium alternifolium (Saxifragaceae).

The complete chloroplast genome of Chrysosplenium ramosum Maxim. and Chrysosplenium alternifolium L. were reported in this study. The chloroplast genomes were 153,460 bp for C. ramosum and 152,619 bp for C. alternifolium. LSC and SSC of 83,670 bp and 17,342 bp were separated by two IRs of 26,224 bp each in C. ramosum. While C. alternifolium contained IRs of 25,992 bp, LSC of 83,524 bp and SSC of 17,111 bp. The chloroplast genome of C. ramosum contains 112 unique genes, including 79 protein-coding genes, four ribosomal RNA genes, and 30 transfer RNA genes. And the chloroplast genome of C. alternifolium contains 112 unique genes, including 79 protein-coding genes, four ribosomal RNA genes, and 30 transfer RNA genes. In addition, the rps12 gene was recognized as a trans-spliced gene and 17 intron-containing genes were also detected.
