Complete chloroplast genome of Ulleung Island endemic basswood, Tilia insularis (Malvaceae), in Korea

The first complete chloroplast genome sequences of Korean endemic basswood in Ulleung Island, Tilia insularis, were reported in this study. The T. insularis plastome was 162,565 bp long, with the large single-copy (LSC) region of 91,100 bp, the small single-copy (SSC) region of 20,381 bp, and two inverted repeat (IR) regions of 25,542 bp. The plastome contained 131 genes, including 86 protein-coding, eight ribosomal RNA, and 37 transfer RNA genes. The overall GC content was 36.5%. Phylogenetic analysis of 14 representative plastomes within the family Malvaceae suggests that T. insularis is closely related to other congeneric species in subfamily Tilioideae.
