AI Article Synopsis
- Mungbean (Vigna radiata) is a fast-growing legume mostly cultivated in developing Asian countries, and researchers have created a draft genome sequence for it to advance genetic studies in related legumes.
- The study indicates that the domesticated mungbean diverged from its wild relatives before domestication, indicating a complex evolutionary history.
- Additionally, the discovery of genomic evidence from a tetraploid Vigna species reveals recent allopolyploid events, and the construction of a species tree helps improve understanding of the genetic relationships among various Vigna species.
Article Abstract
Mungbean (Vigna radiata) is a fast-growing, warm-season legume crop that is primarily cultivated in developing countries of Asia. Here we construct a draft genome sequence of mungbean to facilitate genome research into the subgenus Ceratotropis, which includes several important dietary legumes in Asia, and to enable a better understanding of the evolution of leguminous species. Based on the de novo assembly of additional wild mungbean species, the divergence of what was eventually domesticated and the sampled wild mungbean species appears to have predated domestication. Moreover, the de novo assembly of a tetraploid Vigna species (V. reflexo-pilosa var. glabra) provides genomic evidence of a recent allopolyploid event. The species tree is constructed using de novo RNA-seq assemblies of 22 accessions of 18 Vigna species and protein sets of Glycine max. The present assembly of V. radiata var. radiata will facilitate genome research and accelerate molecular breeding of the subgenus Ceratotropis.
