Recent advances in geminivirus detection and future perspectives
...ng the last two decades, whitefly-transmitted geminiviruses have emerged as serious pathogens of several agricultural and horticultural crops (like tomato, chillies, cotton, pulses, papaya, cucurbits, okra etc.) causing enormous losses in the tropics, which provide ideal conditions for the perpetuation of viruses and the insect-vector. Despite concerted efforts to contain begomoviruses and their vectors, menacing disease epidemics caused by newly emerging or r...
