The complete chloroplast genome of a Cladrastis yunchunii X.W.Li et G.S

Abstract

Cladrastis yunchunii X.W.Li et G.S is a plant species belonged to the family Papilionaceae. Cladrastis yunchunii is currently found in broad-leaved forests in the limestone area of Luxi County, Yunnan Province. It is suitable for afforestation and urban greening in limestone areas. In this study, for the first time, we report the complete chloroplast genome sequence of C. yunchunii. We sequenced and assembled the entire chloroplast genome of C. yunchuniii. The chloroplast genome was determined to be 158,250 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 84,930 bp and 12,664 bp, respectively, which were separated by a pair of inverted repeats (IR) regions of 30,328 bp. The genome contained 132 genes, including 87 protein-coding genes, 8 rRNA genes, and 37 tRNA genes. The overall GC content of the whole genome is 38.1%, and the corresponding values of the LSC, SSC, and IR regions were 36.4%, 33.6%, and 41.3%, respectively. Phylogenetic analysis suggested that C. yunchunii is closely related to the genus Ormosia in the Papilionaceae.
