India virus (MYMIV) is one of the important biotic constraints to mungbean
and urdbean production. Information on the weed hosts of MYMIV is meager. Ageratum
conyzoides, a common weed in and around the agricultural fields throughout
the year is often seen with yellow vein symptoms. This prompted us to look into
the possibility of A. conyzoides acting as an alternate host of MYMIV.
The present study deals with the characterization of MYMIV in A. conyzoides
from four different locations in and around Kanpur. Of the forty plants of A.
conyzoides showing yellow vein symptoms subjected to the PCR based detection
of viruses causing yellow mosaic disease in pulse crops, 52.5% were found positive
with primers specific to MYMIV. None of the samples gave any amplification with
primers specific to Mungbean yellow mosaic virus and Horsegram yellow
mosaic virus. Presence of DNA A and DNA B of MYMIV was also confirmed by
using specific restriction enzymes to release ~2.7kb DNA fragments from the
product of rolling circle amplification. It is evident from the above two detection
methods that A. conyzoides is a new host of MYMIV. The virus was successfully
transmitted by whiteflies from weed to cultivated hosts (mungbean and urdbean)
and induced typical yellow mosaic symptoms. Since this is a common weed growing
throughout the year, it might be serving as an important source of primary inoculum
of this virus for recurrence of yellow mosaic disease in grain legumes in northern
India.]]>Fauquet, C.M., R.W. Briddon, J.K. Brown, E. Moriones, J. Stanley, M. Zerbini and X. Zhou,2008Geminivirus strain demarcation and nomenclature.]]>153783821Gilbertson, R.L., S.H. Hidayat, R.T.
