Abstract

The first complete chloroplast genome sequence of Jeju Island endemic diploid dandelion, Taraxacum hallaisanense, is reported in this study. The plastome size is 151,554 bp in total length, with one large single copy (LSC; 84,066 bp), one small single copy (SSC; 18,524 bp), and two inverted repeat (IR) regions (IR_a and IR_b, each with 24,482 bp). The overall GC content is 37.7% and the genome contained 129 genes, including 84 protein-coding with 2 pseudogenes (ycf1 and accD), 37 transfer RNA, and 8 ribosomal RNA genes. Phylogenetic analysis of 19 representative plastomes of the Asteraceae suggests that Taraxacum is monophyletic with strong bootstrap support and also that T. hallaisanense is closely related to T. mongolicum.
