Mungbean Yellow Mosaic Disease

Résumé du livre

Mungbean yellow mosaic virus (MYMV), a whitefly-transmitted germinivirus, cayses diseases in a number of leguminous crops in India, but mungbean, blackgram and soubean are most seriously affected. Isolates of the virus differ in host range in their reaction to monoclonal antibodies to other germiniviruses such as the African and Indian cassava mosaic viruses (AACMV, ICMV) and in spot hubridization with nucleic acid probes to ACMV, ICMV and a Thai isolate of MYMV. These differences, however, are not sufficient to clearly define strains (or even viruses themselves) within the MYMV complex. Yltrasstructural changes in the hosts are similar to those in other whitefly-transmitted germiniviruses that have been reported. The virus also causes biochemical changes in the host, some of which differentiate resistant and susceptible varieties. The disease can also be managed by biological control and cultural practices. The virus has also become serious for crops like cowpea in India following the introduction of susceptible germplasm.
