Begomoviruses in India

Chapter

Abstract

Begomoviruses, a group of whitefly-transmitted single-stranded DNA viruses that are widely spread, cause significant economic losses in several important crops in tropical and subtropical regions of India. Begomoviruses have been known to be associated with and cause many diseases in cucurbitaceous, solanaceous, malvaceous vegetable and legume crops in most parts of the country. However, these viruses have emerged as a major threat to vegetable and legume production in India. Tomato, chillies, cucurbits, cotton, okra, legumes, papaya, and cassava are the most seriously affected crops. In recent decades, the most dramatic emergence of begomoviruses has been observed in tomato, chilli, and cucurbits throughout the country specially in tropical areas. The major factors responsible for the emergence of new viruses and their spread in the ecosystem are introduction of viruses, introduction of susceptible crops or genotypes, change in vector population, recombination in viruses, weather factors, and new intensive agricultural practices. This article presents the current understanding of begomovirus diseases in India and the driving forces for their emergence.
