Exogenous delivery of dsRNA for management of mungbean yellow mosaic virus on blackgram.

Exogenous application of dsRNA molecules targeting MYMV genes offers a promising approach to effectively mitigate yellow mosaic disease in blackgram, demonstrating potential for sustainable plant viral disease management. The exogenous application of double-stranded RNA (dsRNA) molecules to control plant viral diseases is gaining traction due to its advantages over conventional methods, such as target specificity, non-polluting nature, and absence of residue formation. Furthermore, this approach does not involve genome modification.

Seed Transmission of Begomoviruses: A Potential Threat for Bitter Gourd Cultivation.

Bitter gourd ( L.), one of the valued vegetable crops in India, is severely affected by yellow mosaic disease caused by two begomoviruses, tomato leaf curl New Delhi virus (ToLCNDV) and bitter gourd yellow mosaic virus (BgYMV). The symptoms are yellowing, distortion of leaf, puckering, and malformed fruits.

Molecular studies on tobacco streak virus (TSV) infecting cotton in Tamil Nadu, India.

Unlabelled: Tobacco streak virus (TSV), the causal agent of cotton necrosis, is of emerging importance in the recent years. Unfortunately, all the cotton varieties and hybrids are susceptible to this virus. Cotton plants cultivated in different districts of Tamil Nadu were surveyed during 2014-2016.
