Abstract

Jatropha curcas mosaic disease is a newly emerging disease that challenges the productivity of a prospective biofuel crop, J. curcas . The aetiology of this disease has not been resolved. Here, we report the complete nucleotide sequences of a Jatropha virus isolated from Dharwad, Southern India. Phylogenetic analysis of the virus genome suggests it is a new strain of Indian cassava mosaic virus . Agroinfiltration of the two cloned viral DNA components produced systemic infection and typical mosaic symptoms in J. curcas , thereby fulfilling Koch’s postulates. The availability of infectious clones will provide a valuable tool to screen J. curcas cultivars for disease resistance and facilitate the generation of virus-resistant J. curcas plants by transgenic technology.
