Abstract
Tomato Leaf Curl New Delhi Virus (ToLCNDV) is an important begomovirus constraint to the production of cucurbitaceous and other crops in India and its subcontinent. In this study first time, symptomatic samples of different cucurbits were collected from Telangana, Uttar Pradesh (Varanasi) and Madhya Pradesh location in India. The symptomatic samples were associated with begomovirus infection was confirmed by PCR amplification using specific universal primers Deng 540/541. Thirteen out of fifteen samples were amplified with newly designed bipartite specific primers JKR 58 F and JKR 59 R. In eleven out of thirteen bipartite samples contain betasatellite, confirmed by PCR amplification using specific primer CLB36F and CLB37R. The amplified PCR product with JKR58F and 59R of bitter gourd sample collected from Telangana was sequenced. The sequence was share 97.53% similarity with ToLCNDV infecting bottle gourd in Haryana in India (FN645905). Phylogenic analysis revealed that ToLCNDV infecting cucurbits are different, from ToLCNDV infecting tomato.
