Transmission, characterization and occurrence of recombination in Indian strain of squash leaf curl China virus associated with yellow mosaic and leaf curl disease of Summer squash.

ABSTRACT: Summer squash is one of the important vegetable crops and its production is hampered by various abiotic and biotic stresses. Of the different biotic stresses, viral infections are responsible for causing great losses to this crop. Diseases caused by begomoviruses are becoming a major constraint in the cultivation of summer squash. Samples from summer squash plants exhibiting severe yellow mosaic and leaf curl symptoms were collected from the Varanasi district of Uttar Pradesh (India) and begomovirus associated with these plants was transmitted through whiteflies (Bemisia tabaci) to healthy squash plants. The relationship between causal virus and whitefly vector was determined. The minimum acquisition access period (AAP) and inoculation feeding period (IFP) required by B. tabaci</
