The draft and characterization of the complete chloroplast genome of Vicia sativa cv. Lanjian No.3

The common vetch (Vicia sativa) is a self-pollinating and diploid annual legume, which provides high-quality protein roughage for ruminants of high altitude areas in China. In this study, we evaluated the V. sativa cv. Lanjian No.3 using Illumina Hiseq 2000 to analyze the chloroplast genome sequence. The results showed that this cultivar chloroplast genome is 121 883 bp in length with only one copy of the IR region. It encodes 109 genes, including 4 ribosomal RNA (rRNA) genes, 29 transfer RNA (tRNA) genes, 75 protein-coding genes, and 1 pseudogene. Compared with other legume species, V. sativa chloroplast genes have few differences in size, order, and structure. This genome sequence has been registered in GenBank under accession number KU053796. The successful sequencing of this genome contributes to chloroplast molecular biology and will be useful in studying genetic breeding and molecular evolution of the common vetch.
