Characteristics of plastomes
The plastome of L. columnaris is circular and quadripartite by having a large single copy (LSC), a small single copy (SSC), and two inverted repeated (IR) regions. The complete plastome size of varied from 164,609 bp to 165,368 bp, with LSC from 82,421 bp to 82,904 bp, SSC from 7,950 bp to 8025 bp, and IRs from 37,028 bp to 37636 bp (Figure 2). The GC content of the whole plastome was 39.2 %. The plastome contained 117 unique genes, including 80 recognized and three predicted protein-coding regions (CDS), 30 tRNA, and 4 ribosomal RNA (rRNA) genes. The IR regions had 14 CDS, seven tRNA, and four rRNA genes.
