Abstract

Keteleeria evelyniana Mast var. pendula Hsüeh, a typical plant species of extremely small population, is faced to be endangered. The complete chloroplast (cp) genome of K. evelyniana var. pendula has been assembled and annotated for the first time in this study. The complete genome in length was found to be 117,139 bp. The genome annotation revealed a total of 118 genes, including 34 transfer RNA (tRNA) genes, 4 ribosomal RNA (rRNA) genes, and 80 protein-coding genes. The maximum-likelihood phylogenetic tree supported that K. evelyniana var. pendula, K. fortune, K. evelyniana, and K. davidiana are clustered in one branch. This complete chloroplast genome helped us to understand the evolution of K. evelyniana var. pendula. These results laid the foundation for future studies on the conservation of this species.
