Genetic Dissection of Phosphorous Uptake and Utilization Efficiency Traits Using GWAS in Mungbean

Mungbean (Vignaradiata L. Wilczek) is an early maturing legume grown predominantly in Asia for its protein-rich seeds. P deficiency can lead to several physiological disorders which ultimately result a low grain yield mungbean. The genetic dissection of PUpE (Puptake efficiency) and PUtE (P utilization traits are essential breeding mungbean varieties with high uptake efficiency. study involves association mapping panel consisting 120 genotypes were phenotyped total dry weight, concentration, uptake, efficiency under (LP) normal (NP) conditions hydroponic system. A genotyping-by-sequencing (GBS) based genome-wide (GWAS) approach was employed dissect the complexity at level This has identified 116 SNPs 61 protein-coding genes these, 16 have been found enhance phosphorous mungbeans. We six expression (VRADI01G04370, VRADI05G20860, VRADI06G12490, VRADI08G20910, VRADI08G00070 VRADI09G09030) root, shoot apical meristem leaf, indicating their role regulation present three also validated using Sanger sequencing approach.
