| characterization of begomovirus components from a weed suggests that begomoviruses may associate with multiple distinct dna satellites. | a begomovirus disease complex associated with sonchus arvensis, a common weed in pakistan was studied using cloning, nucleic acid sequencing and phylogenetic analysis. the complex associated with this weed consists of a monopartite begomovirus and several distinct betasatellites and alphasatellites. the monopartite begomovirus associated with yellow vein disease of sonchus arvensis showed 95-99% nucleotide sequence identity with alternanthera yellow vein virus (alyvv) reported from china, vietna ... | 2010 | 20306125 |
