Abstract

Lindera angustifolia is mainly distributed in the temperate climate zone of China but shows an extraordinary distribution, disjunctively isolated on the western coastal islands of Korea. We therefore present the complete chloroplast genome of Korean L. angustifolia. The complete plastome was 152,836 bp in length, with an overall GC content of 39.2%. A large single copy (93,726 bp) and a small single copy (18,946 bp) of the genome were separated by a pair of inverted repeats (20,082 bp). The genome consists of 125 genes, including 81 protein-coding, eight ribosomal RNA, and 36 transfer RNA genes. While five RNA editing genes (psbL, rpl2, ndhB×2, and ndhD) were identified in L. angustifolia from China, the "ndhD" gene was not recognized as an RNA editing site in the corresponding Korean individual. A phylogenetic analysis revealed that Korean L. angustifolia is most closely related to the Chinese L. angustifolia with strong bootstrap support, forming a sister group of L. glauca.
