novel begomoviruses recovered from pavonia sp. in brazil.begomoviruses are whitefly-transmitted, single-stranded dna viruses that cause serious infections in crop plants and are often also associated with non-cultivated plants. here, we report the detection of two new begomoviruses in pavonia sp. (malvaceae). sequence comparisons and phylogenetic analysis showed that these novel viruses are related to new world begomoviruses. the nucleotide sequences of the dna-a of both viruses had the highest similarity to abutilon mosaic bolivia virus (abmbov). bas ...201626660167
the genomes of four novel begomoviruses and a new sida micrantha mosaic virus strain from bolivian weeds.begomovirus is the largest genus within the family geminiviridae and includes economically important plant dna viruses infecting a broad range of plant species and causing devastating crop diseases, mainly in subtropical and tropical countries. besides cultivated plants, many weeds act as virus reservoirs. eight begomovirus isolates from bolivian weeds were examined using rolling-circle amplification (rca) and restriction fragment length polymorphism (rflp). an efficient, novel cloning strategy ...201121170729
