Mungbean (Vigna radiata L. Wilczek) an important legume crop with valuable nutritional and health benefits is severely affected by drought conditions. Desiccation tolerance is a capacity of seeds to survive and maintain physiological activities during storage and stress conditions. LEA proteins are group of stress associated proteins that help the plants survive water deficit stress. Here we have performed genome-wide analysis of mungbean LEA (VrLEA) genes, and also insilico physical/functional characterization. Gene-positioning showed that 307 VrLEAs are present in all the eleven chromosomes, but are unevenly distributed.Upstream promoter sequence analysis of LEA genes revealed the occurrence of MYB transcription factor (TF)in higher number compared to other TFs i.e., bZIP, AP2, WRKY, NAC and bHLH.Further, we downstreamed our analysis to fewer VrLEAs, based on drought responsive data. The VrLEAs obtained from the earlier experimental data were examined for its organelle localization and found that they are intracellular functional proteins.
