Journal ArticleDOI
A geminivirus betasatellite damages the structural and functional integrity of chloroplasts leading to symptom formation and inhibition of photosynthesis
Dhriti Bhattacharyya,Prabu Gnanasekaran,Reddy Kishore Kumar,Nirbhay Kumar Kushwaha,Veerendra Kumar Sharma,Mohd Aslam Yusuf,Supriya Chakraborty +6 more
TL;DR: A satellite DNA-encoded protein (βC1) is localized in the chloroplast and the intercellular events associated with βC1-induced photosynthetic inhibition and vein clearing symptom formation are discussed.
Journal ArticleDOI
Complexity of begomovirus and betasatellite populations associated with chilli leaf curl disease in India.
R. Vinoth Kumar,Achuit K. Singh,Ashish Kumar Singh,Tribhuwan Yadav,Tribhuwan Yadav,Saumik Basu,Saumik Basu,Nirbhay Kumar Kushwaha,Brotati Chattopadhyay,Supriya Chakraborty +9 more
TL;DR: Analysis of samples collected in the survey indicates that ChiLCD-infected plants are associated with a complex of begomoviruses (including one previously unreported species) with a diverse group of betasatellites found in crops and weeds, and demonstrates the crucial role of betAsatellites in severe disease development in Capsicum spp.
Journal ArticleDOI
The replication initiator protein of a geminivirus interacts with host monoubiquitination machinery and stimulates transcription of the viral genome
TL;DR: The current study reveals that the ChiLCV Rep protein binds the viral genome and interacts with NbUBC2 and NbHUB1 for the monoubiquitination of hist one 2B that subsequently promotes trimethylation of histone 3 at lysine 4 on Chi LCV mini-chromosomes and enhances transcription of the viral genes.
Journal ArticleDOI
Synergistic interaction among begomoviruses leads to the suppression of host defense-related gene expression and breakdown of resistance in chilli
TL;DR: It is suggested that synergistic interaction among begomoviruses created permissive cellular environment in the resistant chilli plants which leads to breakdown of natural resistance, a phenomenon observed for the first time in chilli.
Journal ArticleDOI
Dynamics of a geminivirus-encoded pre-coat protein and host RNA-dependent RNA polymerase 1 in regulating symptom recovery in tobacco
Saumik Basu,Nirbhay Kumar Kushwaha,Ashish Kumar Singh,Pranav Pankaj Sahu,R. Vinoth Kumar,Supriya Chakraborty +5 more
TL;DR: ToLCNDV-AV2 is essential for repression of - antiviral silencing mediated by RNA-dependent RNA polymerase 1 and is responsible for contrasting symptom development in Nicotiana species infected with different geminiviruses.
