The complete chloroplast genome sequence of limestone endemic, Zabelia tyaihyoni (Caprifoliaceae), in Korea

Abstract

The first complete chloroplast genome sequence of Korean limestone endemic, Zabelia tyaihyoni, was reported in this study. The plastome size was 156,449 bp in total length, with one large single copy (LSC; 89,242 bp), one small single copy (SSC; 17,331 bp), and two inverted repeat (IR) regions (IR a and IR b , each with 24,938 bp). The overall GC content was 38.3% and the genome contained 128 genes, including 83 protein-coding with 3 pseudogenes (two ycf2 and accD), 37 transfer RNA and 8 ribosomal RNA genes. Phylogenetic analysis of 21 representative plastomes within the Caprifoliaceae suggests that Zabelia formed a monophyletic clade with 100% bootstrap value and Z. tyaihyoni was closely related to Z. biflora and Z. corymbosa.

Population Genomics Study and Implications for the Conservation of Zabelia tyaihyonii Based on Genotyping-By-Sequencing

“…It is important to establish a conservation strategy based on ecological conditions and the genetic diversity suitable for each species to prevent extinction and maintain continuous natural populations [ 13 , 14 , 15 ]. Previous studies on Z. tyaihyonii were mainly focused on systematics [ 16 , 17 , 18 , 19 , 20 , 21 ], and only four studies have been performed on its conservation biology [ 4 , 10 , 22 , 23 ]. The ecological characteristics of Z. tyaihyonii habitats were very thoroughly described in three studies conducted on all native habitats [ 4 , 10 , 23 ].…”
