Genome wide identification of mungbean (Vigna radiata [L.] R. Wilczek) Late Embryogenesis Abundant (LEA) protein gene family

<p>Mungbean (<i>Vigna radiata </i>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. <i>LEA </i>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 (<i>VrLEA</i>) genes, and also <i>insilico</i> physical/functional characterization. Gene-positioning showed that 307 <i>VrLEAs </i>are present in all the eleven chromosomes, but are unevenly distributed.Upstream promoter sequence analysis of <i>LEA</i> genes revealed the occurrence of MYB transcription factor (TF)in higher number compared to other TFs <i>i.e</i>., bZIP, AP2, WRKY, NAC and bHLH.Further, we downstreamed our analysis to fewer <i>VrLEAs,</i> based on drought responsive data. The <i>VrLEAs </i>obtained from the earlier experimental data were examined for its organelle localization and found that they are intracellular functional proteins.</p>
