First report of Tomato leaf curl New Delhi virus infecting Eclipta prostrata in Pakistan

Molecular Evidence for Occurrence of Tomato leaf curl New Delhi virus in Ash Gourd (Benincasa hispida) Germplasm Showing a Severe Yellow Stunt Disease in India

“…ToLCNDV is known to infect tomato in India since nearly two decades, but during the last one decade, its host range has increased enormously to various crops such as potato [21], papaya [12], eggplant [11] okra [23] and several cucurbitaceous vegetables like bottle gourd, bitter gourd, cucumber, ivy gourd, long melon, pumpkin, ridge gourd and watermelon in northern India and chayote in north-western India [7,16,17,20]. In Pakistan, besides tomato, ToLCNDV was also reported on crops like chilli [5], bitter gourd [18], and on weed Eclipta prostrata [3]. In Thailand, ToLCNDV has been reported to infect bottle gourd, cucumber and muskmelon [6].…”

Begomoviruses and Their Emerging Threats in South Korea: A Review

“…Tomato leaf curl New Delhi virus (ToLCNDV), a devastating species in Indian sub-continent has been reported on two commonly growing weeds viz. Croton bonplandianum and Eclipta prostrata in India and Pakistan, respectively (Haider et al, 2006;Reddy et al, 2005). Hang and Zhou (2006) surveyed weeds to identify the alternate host of Papaya leaf curl China virus (PaLcuCNV) recently causing a severe leaf curl disease on papaya in southern China, and found that Corchoropsis timentosa is the alternate host of the PaLCuCNV and play an important role in papaya leaf curl disease epidemiology.…”

“…Similarly, Tomato leaf curl New Delhi virus (ToLCNDV) was first time recorded in north India in 1995 (Srivastava et al, 1995) and subsequently reported across the country (Khan et al, 2006;Padidam et al, 1995;Raj et al, 2005;Sohrab et al, 2003;Usharani et al, 2004). Later on, the virus has been reported from other neighboring countries like Pakistan (Haider et al, 2006;Hussain et al, 2004;Hussain et al, 2005;Mansoor et al, 1997;Mansoor et al, 2000b;Tahir and Haider, 2005), Bangladesh (Maruthi et al, 2005), Thailand (Ito et al, 2008) and Indonesia (Mizutani et al, 2011) where it has great concern in the association of various commercial crop diseases.…”

Analysis of coat protein gene sequences of begomoviruses associated with different weed species in India

“…Interestingly, it showed only 68% and 45% nsi, respectively, with the CP gene (AM259382) and betasatellite (AJ967003) of the begomovirus complex associated with Sida yellow vein disease originated from southern India (unpublished). The CP gene of the begomovirus associated with Eclipta yellow vein disease in eastern India (EU188920) showed its close relationship (95% nsi) with Alternanthera yellow vein virus which infects Eclipta plants in China (EU286797) (unpublished) and a distant relationship (only 63% nsi) with Tomato leaf curl New Delhi virus (AJ889185) which infects Eclipta plants in Pakistan(Haider et al 2006). Therefore, the present begomovirus isolate which clustered with New World begomoviruses in the phylogenetic tree is probably an isolate of Alternanthera yellow vein virus although full genome sequence is required to confirm its identity.…”
