Abstract

Lithocarpus longinux (Hu) Chun ex Y.C.Hsu & H.Wei Jen is a Critically Endangered tree distributed in Ma-li-po county in the Southeastern Yunnan Province China. Less than ten individuals have been found since the species was established 70 years ago. In this study, we assembled and annotated the complete chloroplast genome of L. longinux. The complete chloroplast genome of the species is 161,420 bp in length and has a GC content of 36.8%, including one large single-copy region (LSC, 90,409 bp), one small single-copy region (SSC, 19,255 bp), and two copies of inverted repeat regions (IRs, 25,878 bp). A total of 112 unique genes were detected, including 81 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. Phylogenetic analysis of 31 representative chloroplast genomes of the Fagales suggests Lithocarpus is monophyletic with strong bootstrap support and that L. longinux is closely related to L. balansae.
