| Abstract: | In October 2009, vein yellowing disease was observed on the weeds Crassocephalum crepidioides and Ageratum conyzoides in a subtemperate region in northern India. Ageratum enation virus (AEV), along with a nanovirus like satellite DNA 1, was found to be associated with both weeds. The isolates had 99% identity with each other and with an isolate of AEV reported from Zinnia elegans from this region. To the best of our knowledge, this report is the first of any begomovirus infection in C. crepidioides in India and the first on AEV infecting C. crepidioides worldwide and A. conyzoides in India. |
