Reaction in Geminivirus protein structure and function Fondong 2013 Geminivirus genomes are replicated through the interaction between virus Rep and several host proteins The Rep also interacts with itself and the virus replication enhancer protein REn which is another essential component of the geminivirus replicase complex that interacts with host DNA polymerases α and δ Jan 26 2023 Geminiviruses are emerging plant viruses that cause serious diseases in several crops worldwide This review summarizes the pathological and economic impacts the infection cycle and the molecular techniques for controlling geminiviruses Family Geminiviridae ICTV Molecular study of geminiviruses Complex biology host The rising threat of geminiviruses molecular insights into Jan 4 2023 Geminivirus satellite βC1 can exploit NbbZIP60 and the chaperons such as BiP and CRT to increase protein accumulations in the early stage of infection However accumulating aggregated viral Oct 8 2013 Some geminivirus proteins can interact with or modify components of the host ubiquitylation and sumoylation machinery resulting in global or targeted changes in host protein modifications Plant responses to geminivirus infection guardians of the This genus includes three species Apple geminivirus 1 Liang et al 2015 Grapevine geminivirus A Al Rwahnih et al 2017 and Juncus maritimus geminivirus 1 Claverie et al 2018 Members of the mentioned species have been described from asymptomatic plants and infect dicot apple grapevine and monocot Juncus maritimus plants All Geminivirusinfected plants exhibit many symptoms including distortion leaf curling thickening vein yellowing stunted growth and mosaic patterns Geminiviruses are rapidly diversifying owing to the transportation of plant materials viral evolution new agricultural practices climate change and global trade NavasCastillo et al 2011 The geminivirus CP is a late gene and is the only structural protein of geminivirus particles Stanley and Gay 1983 It is encoded by the AV1 also AR1 ORF in bipartite geminiviruses and by the V1 ORF in monopartite geminiviruses Zhang W et al 2001 Jul 13 2021 Geminiviruses are plant viruses with limited coding capacity Geminivirusencoded proteins are traditionally identified by applying a 10kDa arbitrary threshold however it is increasingly clear May 21 2009 The ATPase activity of the geminivirus Rep protein was proven to be essential for replication Koonin and Ilyina 1992 observed a limited sequence similarity between the three conserved motifs of the RCR Reps of geminiviruses and plasmids of Grampositive bacteria and suggested that geminiviruses descend from bacterial replicons 17 Researchers reveal how geminiviruses cause devastating Geminivirus protein structure and function PMC The tomato gene Ty6 encoding DNA polymerase delta subunit Jun 1 2022 The new proposed guideline is that if fulllength nucleotide sequence identity of freshly recognized geminivirus is 89 using clustral V algorithm excluding Mastreviruses which has 75 cutoff parameter then it could be recognized as fresh specie while the klasemen sea games 2022 sepak bola sequence identity is 89 so it could be recognized as a member of same species The geminivirus Rep protein is a site and strandspecific endonuclease that nicks and ligates strand viral DNA at the same position in vitro Laufs et al 1995 Orozco and HanleyBowdoin 1996 The nick leaves a 3OH end that is used as a primer for leadingstrand synthesis by the host DNA polymerase Geminivirusencoded proteins have so far been identified taking into consideration an arbitrary threshold of 10 kDa below which potential proteins were discarded However it is increasingly clear that small proteins and peptides play relevant roles in biological systems hence calling for the reconsideration of this criterion Geminiviruses a tale of a plasmid becoming a virus PMC Jul 9 2021 This article summarizes the current knowledge of plants antiviral defence mechanisms against geminiviruses a group of circular singlestranded DNA viruses that cause crop loss worldwide It covers the molecular aspects of geminivirus replication transmission and pathogenesis as well as the host factors and signalling pathways involved in resistance Métodos de data mining para extração de

ScienceDirect Topics 3 days ago Key message The tomato Ty6 gene conferring resistance against begomoviruses has been cloned and shown to be a variant of DNA polymerase delta subunit 1 Abstract Ty6 is a major resistance gene of tomato that provides resistance against monopartite and bipartite begomoviruses The locus was previously mapped on chromosome 10 and in this study we finemapped Ty6 to a region of 47 kb Schematic overview of plant immune strategies against geminiviruses Geminivirus infection initiates with the release of viral ssDNA into the nucleus subsequently leads to the replication transcription and translation of viral genome A Plants counteract geminivirus genetic life cycle via multiple host factors GRAB interacts with RepA and REPercussions how geminiviruses recruit host factors for Geminiviruses encode additional small proteins with specific Geminivirus infection induces hypersensitive response HR and senescencerelated genes without developing a visible cell death phenotype More specifically the geminivirus proteins Rep NSP and V2 have been shown to induce HR 515253 In contrast some geminiviral proteins possess the capacity of suppressing HRlike cell death Geminiviridae Wikipedia Geminiviridae is a family of plant viruses with circular ssDNA genomes and geminate capsids They cause various diseases and are transmitted by different insect vectors
