Geminiviridae - an overview ScienceDirect Topics
Geminiviridae is a family of plant viruses that encode their genetic information on a circular genome of single-stranded (ss) DNA. There are 520 species in this family, assigned to 14 genera. Diseases associated with this family include: bright yellow mosaic, yellow mosaic, yellow mottle, leaf curling, stunting, streaks, reduced yields. They have single-stranded circular DNA genomes enc… WebMay 15, 2007 · The present taxonomic division of the Geminiviridae into four genera is in part attributable to recombination between progenitor viruses; for example, viruses of the genus Curtovirus, geminiviruses that are leafhopper-transmitted but with the replication genes more similar to the whitefly-transmitted geminiviruses, most likely result from a … WebJun 26, 2024 · Several factors such as recombination, pseudo-recombination, microsatellites, mutations, nucleotide substitutions, synergism, and vector-mediated transmission drive the rapid emergence … iphone death screen
