Weeds are widely distributed throughout the world and have high environmental adaptability. Weeds are considered as a source of new viruses and reservoirs of unidentified economically important viruses but are often neglected during diversity studies. Many scientific reports have demonstrated that weeds serve as reservoir or alternative hosts for begomovirus (family Geminiviridae) survival and spread in the absence of the main crops. Thus, there is a pressing need for additional information on the diversity and distribution of begomoviruses associated weeds, which likely serve as virus reservoirs. This review thus presents a tip of the iceberg of the diversity of begomoviruses associated weeds in India and other parts of the world.

“…There are reports on occurrence of Jatropha mosaic virus on J. gossypifolia, a weed plant from Puerto Rico and Jamaica (Bird 1957; Roye et al 2006) and natural infection of Jatropha mosaic virus on J. curcas has been reported in south India. However, the Jatropha mosaic virus infected J. curcas plants exhibited mosaic, leaf distortions and blistering (Narayana et al 2006).…”

Abstract. The association of a begomovirus with Jatropha mosaic disease has been found in north India. The begomovirus possessed highest identities and closest relationships with Indian and Sri Lankan cassava mosaic virus isolates.Jatropha curcas L. (of family Euphorbiaceae) is grown in India as a major commercial fuel (bio-diesel) crop. The natural occurrence of a mosaic disease was noticed on J. curcas growing in experimental plots of the National Botanical Research Institute (NBRI), Lucknow, India in the years 2006 and 2007. The disease incidence was significant (~25%). The symptoms of the disease were severe with leaf mosaic and reduced size (Fig. 1a), and stunting of whole plants (Fig. 2). With an acquisition and inoculation period of 24 h, the disease could be transmitted by whitefly (Bemisia tabaci) in a persistent manner but could not be transmitted through mechanical inoculations using leaf sap of an infected plant onto J. curcas seedlings. The whitefly-inoculated J. curcas seedlings developed systemic mosaic and chlorosis at 25--30 days post-inoculation (Fig. 1b). Therefore, infection of a whitefly-transmitted begomovirus was suspected.To confirm the association of a begomovirus, polymerase chain reaction (PCR) was carried out using as template total DNA extracted from naturally infected J. curcas leaf tissues. Three sets of begomovirus genus specific primers were employed: Deng A and Deng B (Deng et al. 1994), PALIv 1978 and PARIc 496 (Rojas et al. 1993, and those designed to amplify the coat protein (CP) gene of Tomato leaf curl virus (TLCV, Singh 2005). PCRs were set up in a 50 mL reaction mixture containing: template DNA (100 ng), dNTPs (10 mM each), primers (each 25 pmol), Pfu DNA polymerase (1.5 U), assay buffer (5 mL 10Â Banglore Genei Pvt. Ltd) and were cycled 30 times (denaturation: 94 C for 5 min; specific annealing temperatures for 1 min according to the primers used; and extension: 72 C for 1.5 min). The annealing temperatures for Deng, Rojas and TLCV-CP primers were 52 C, 50 C and 47 C, respectively. The final extension cycle was 5 min

“…across the world: Jatropha mosaic virus on J. gossypifolia in Jamaica [16,17]; African cassava mosaic virus on Jatropha multifida in India and East and West Africa [18] and a begomovirus closely related to Indian cassava mosaic virus and Sri Lankan cassava mosaic virus on Jatropha curcas in India [19][20][21][22][23]. We report here complete nucleotide sequence of Croton yellow vein mosaic virus and DNA-b associated with yellow vein mosaic disease of J. gossypifolia for the first time in India.…”

A severe yellow vein mosaic disease was noticed on several Jatropha gossypifolia plants growing nearby agriculture fields at Lucknow, India. Diseased plants exhibited yellow vein mosaic, leaf deformation, vein swelling and stunting. A population of whiteflies (Bemisia tabaci) was also noticed in the vicinities; therefore, begomovirus infection was suspected. To confirm begomovirus association, total DNA was isolated from symptomatic leaf samples and subjected to PCR using DNA-A, DNA-B and DNA-β-specific primers. DNA-A and DNA-β was successfully amplified but several attempts failed to amplify DNA-B indicating monopartite nature of the begomovirus. The sequence analysis of amplicons revealed the presence of 2757 nucleotides of DNA-A genome (EU727086) and 1315 nt of DNA-β molecule (EU604296). The sequence analysis of DNA-A (EU727086) revealed the highest 96% identities and closest relationship with Croton yellow vein mosaic virus (CYVMV, AJ507777) infecting Croton bonplandianum in India. The DNA-β (EU604296) showed the highest 96% sequence identity and closest phylogenetic relationship with CYVMV-associated DNA-β (AM410551) isolated from Croton sp. in Pakistan. Based on the highest sequence identities and closest phylogenetic relationships of the DNA-A genome and DNA-β molecule with respective sequences of various isolates of Croton yellow vein mosaic virus, the begomovirus associated with yellow vein mosaic disease of J. gossypifolia was identified as an isolate of Croton yellow vein mosaic virus.
