Globally, yellow mosaic disease (YMD) remains a major constraint of mungbean
production, and management of this deadly disease is still the biggest challenge. Thus,
finding ways to manage YMD including development of varieties possessing resistance
against mungbean yellow mosaic virus (MYMV) and mungbean yellow mosaic India virus
(MYMIV) is a research priority for mungbean crop. Characterization of YMD resistance
using various advanced molecular and biochemical approaches during plant–virus
interactions has unfolded a comprehensive network of pathogen survival, disease
severity, and the response of plants to pathogen attack, including mechanisms of YMD
resistance in mungbean. The biggest challenge in YMD management is the effective
utilization of an array of information gained so far, in an integrated manner for the
development of genotypes having durable resistance against yellow mosaic virus (YMV)
infection. In this backdrop, this review summarizes the role of various begomoviruses, its
genomic components, and vector whiteflies, including cryptic species in the YMD
expression. Also, information about the genetics of YMD in both mungbean and
blackgram crops is comprehensively presented, as both the species are crossable, and
same viral strains are also found affecting these crops. Also, implications of various
management strategies including the use of resistance sources, the primary source of
inoculums and vector management, wide-hybridization, mutation breeding, markerassisted
selection (MAS), and pathogen-derived resistance (PDR) are thoroughly
discussed. Finally, the prospects of employing various powerful emerging tools like
translational genomics, and gene editing using CRISPR/Cas9 are also highlighted to
complete the YMD management perspective in mungbean.
