The entire mitogenome of wild mung bean (Vigna radiata var. sublobata TC1966) was identified as a circular molecule of 402,981 bp length. The wild mung bean mitogenome encoded 3 rRNAs, 16 tRNAs, and 33 proteins. A phylogenetic tree was reconstructed using the 18 protein-coding genes of 14 legumes and one close species, Ricinus communis. Our phylogenetic analysis suggests that the wild mung bean clustered with the Vigna radiata var. radiata, as well as, the species of Vigna and Glycine appeared as a monophyletic group. This complete mitogenome sequence provides a genomic resource for further studies in mung bean breeding and domestication.
