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

Tomato Leaf Curl New Delhi Virus: An Emerging Virus Complex Threatening Vegetable and Fiber Crops

“…Between 2000 and 2010, ToLCNDV has been reported to be associated to infections of various hosts such as Abelmoschus esculentus , Ageratum spp., Capsicum annuum , Carica papaya , Citrullus lanatus , C. pepo , Cyamopsis tetragonoloba , Daucus carota , Hibiscus cannabinus , Jatropha spp., L. siceraria , Momordica charantia , Solanum melongena , and Solanum tuberosum [ 11 , 12 , 13 , 14 , 15 ]. Further, ToLCNDV was detected infecting Benincasa hispida , Catharanthus roseus , Chenopodium album , Coccinia grandis , Jasminum multiflorum , Papaver somniferum , Sauropus androgynus and Trichosanthes cucumerina , mainly from India and Pakistan [ 16 , 17 ]. Importantly, the occurrence of ToLCNDV associated with cotton leaf curl disease was reported from Pakistan over the period 2013–2015 [ 18 ], which suggests that ToLCNDV, along with several other known cotton-infecting monopartite begomoviruses, could pose a serious threat to cotton cultivation in Pakistan.…”

Molecular evidence for the occurrence of tomato leaf curl New Delhi virus on chayote (Sechium edule) in southern India

“…ToLCNDV is causing serious threats to various horticultural crops in the countries of the Asian continent viz., India, Pakistan, Bangladesh, Philippines and Thailand [5,6,17]. ToLCNDV was originally reported to infect solanaceous vegetables since 1980s, however in recent days it has extended its host range towards the cucurbitaceous vegetables viz., pumpkin, bottle gourd, bitter gourd, ash gourd, cucumber, ridge gourd, watermelon, long melon and ivy gourd throughout the globe [4,9,12,13,15]. Predominantly, squash leaf curl China virus (SLCCNV) and ToLCNDV are the two major begomoviruses reported on the cucurbits from India.…”

“…Previously [7] reported the occurrence of ToLCNDV on chayote from North Western India only based on the partial coat protein gene and the present study further confirms the occurrence of ToLCNDV on chayote leading to major threat for the cultivation of chayote in Southern India. Roy et al [13] reported that the natural occurrence of ToLCNDV on ash gourd in North India. It found to have its perpetuation even in the absence of main host and its subsequent spread to tomato.…”

A Major QTL Located in Chromosome 8 of Cucurbita moschata Is Responsible for Resistance to Tomato Leaf Curl New Delhi Virus

“…], cucumber (Cucumis sativus L.), watermelon (Citrullus lanatus L), melon (C. melo L.), and different types of squashes (Cucurbita spp.) (Sohrab et al, 2003;Ito et al, 2008;Singh et al, 2009;Chang et al, 2010;Roy et al, 2013). Recently, it has been reported to be affecting species of other plant families, such as opium poppy (Papaver somniferum L., Papaveraceae) (Srivastava et al, 2016), cotton (Gossypium hirsutum L., Malvaceae) (Zaidi et al, 2016), soybean (Glycine max, Fabaceae L.…”
