spread Recent research has primarily focused on viral movement proteins and their interactions with the cellular host transport machinery which has significantly BegomovirusHost Interactions Viral Proteins Orchestrating Aug 30 2016 A review of the molecular diversity epidemiology and management of Begomovirus a family of DNA viruses transmitted by whiteflies to dicotyledonous plants The chapter covers the genome organization vector host and environmental factors affecting the disease outbreak and spread Feb 16 2021 Since the early 1990s squash production in Costa Rica has been affected by a whiteflytransmitted disease characterized by stunting and yellow mottling of leaves The squash yellow mottle disease SYMoD was shown to be associated with a bipartite begomovirus originally named squash yellow mild mottle virus SYMMoV It was subsequently established that SYMMoV is a strain of melon chlorotic Nov 18 2019 The genus Begomovirus is one of the nine genera in the family Geminiviridae Zerbini et al 2017 and its members as with the rest of geminivirids have a unique particle morphology consisting of twinned geminate quasiicosahedra Begomoviruses have monopartite or bipartite genomes of circular singlestranded DNA The search for putative begomovirus receptors and for proteins regulating the translocation of begomoviruses in B tabaci has witnessed new developments Researchers have been able to select for poor begomovirus transmitters within whitefly populations In these insects WmCSV and TYLCV were unable to cross the gut barrier into the haemolymph 56525 Begomovirus geminiviridae The Begomovirus is the genus with the largest number of species that infect okra To date 25 species of the genus Begomovirus were reported see Section 6251 and Table 561 all

six different genera including Begomovirus Becurtovirus Turncurtovirus Potyvirus Cucumovirus and Alphaendornavirus were detected in the main Begomovirus An Introduction Springer Jun 1 2023 Begomoviruses are emerging plant viruses that cause devastating diseases in crops worldwide They are transmitted by whiteflies of the B tabaci complex and have high recombination and host range Begomovirus is a genus of plant viruses with a bipartite genome and a wide host range They are transmitted by whiteflies and cause severe diseases in many crops especially tomatoes peppers and cassava
