Preface
Begomoviruses of family Geminiviridae are fast-evolving plant viral pathogens with small circular single-stranded DNA as genome. They cause diseases in various crops in the tropical and subtropical regions, and with change in climatic conditions due to global warming, now temperate regions are also under the threat of these viruses. They are transmitted by the whitefly (B. tabaci) and enjoy a wide host range. Begomoviruses are geminate particles and can be either monopartite or bipartite based on the number of genomic components present as one (DNA-A) and two (DNA-A and DNA-B), respectively. The two genomic components (bipartite) designated as DNA-A and DNA-B are of ~2,600–2,800 nucleotides each. A number of serious diseases of commercially cultivated crops of the Fabaceae, Malvaceae, Solanaceae, and Cucurbitaceae families are caused by begomoviruses which are considered as a threat to their cultivation in India and abroad. Accurate and reliable diagnosis is important for s
