Association of geminivirus infection with yellow green mosaic disease of Cucumis sativus: diagnosis by nucleic acid probes.

Geminivirus association with yellow mosaic disease of C. sativus has been investigated by dot/slot blot hybridization tests using nucleic acid probe derived from DNA-B of Indian Tomato Leaf Curl geminivirus. The disease was transmitted experimentally on C. sativus by whitefly, Bemisia tabaci. Some weeds were also found to harbour geminivirus infection in dot/slot blot hybridization tests.
