Abstract

Abstract: Cycas bifida (Dyer) K.D.Hill (2004) is an extremely small population-protected species of China. In this study, we reported the first chloroplast genome sequence of C. bifida . The chloroplast genome of C. bifida included two single-copy regions (large single-copy (LSC) and small single-copy (SSC)) and a pair of inverted repeats (IRs) regions comprising 88, 946 bp, 23, 107 bp, and 25, 053 bp, respectively. The complete chloroplast genome of C. bifida contains 131 genes, including 86 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes. The overall GC content of the C. bifida chloroplast genome is 39.41%, and the LSC, SSC, and IR regions occupy 38.70%, 36.52%, and 42.02%, respectively. A phylogenetic analysis was performed based on complete chloroplast genomes from 15 species and found that C. bifida was closely related to Cycas szechuanensis W.C.Cheng & L.K.Fu.
