Deciphering Temporal Metabolome Dynamics in Response to MYMV: Contrasting Patterns in Resistant and Susceptible Blackgram ( L. Hepper) Cultivars.

Blackgram ( L. Hepper) production is hindered by mungbean yellow mosaic virus (MYMV) with disease incidence up to 85% in hot spot locations of Tamil Nadu, India. Field screening of 50 genotypes identified Mash 114 as resistant and CO 5 as susceptible cultivars.

Seed-borne nature of a begomovirus, Mung bean yellow mosaic virus in black gram.

The yellow mosaic viruses (YMV) infecting legumes are considered to be the most devastating begomoviruses as they incite considerable yield loss. The yellow discoloration of pods and seeds of infected plants and symptom emergence in the very first trifoliate leaf of the plants in the field were suggestive that the virus may be seed borne, which was investigated in the present study. The distribution of the virus in various parts of the seeds of black gram (Vigna mungo L.
