Geminivirus infection often causes severe vein clearing symptoms in hosts. Recently a betasatellite has emerged as key regulator of symptom induction. To understand the host–betasatellite interactions process development, systematic study was carried out involving induced by associated with radish leaf curl disease (RaLCB) Nicotiana benthamiana. It been found that βC1 protein localized to chloroplasts host cells, and RaLCB lacking βC1, which failed produce symptoms, had no effect on...
Chilli, which encompasses several species in the genus Capsicum, is widely consumed throughout world. In Indian subcontinent, production of chilli constrained due to leaf curl disease (ChiLCD) caused by begomoviruses. Despite considerable economic consequences ChiLCD on cultivation India, there have been scant studies genetic diversity and structure begomoviruses that cause this disease. Here we report a comprehensive survey across major chilli-growing regions India. Analysis samples...
Isolates of two distinct begomovirus species, the severe strain species Tomato leaf curl New Delhi virus (tomato virus-[India:New Delhi:Severe:1992]; ToLCNDV-[IN:ND:Svr:92], bipartite) and Varanasi Gujarat virus-[India:Varanasi:2001]; ToLCGV-[IN:Var:01], mono/bipartite) infect tomato (Lycopersicon esculentum) cause yield losses in northern India. This study investigated infectivity properties genomic components these species. Both pseudorecombinants were infectious Nicotiana benthamiana,...
Geminiviruses constitute a group of plant viruses, with ssDNA genome, whose replication in the nucleus an infected cell requires function geminivirus-encoded initiator protein (Rep). Our results suggest that monoubiquitinated histone 2B (H2B-ub) promotes tri-methylation 3 at lysine 4 (H3-K4me3) on promoter Chilli leaf curl virus (ChiLCV). We isolated homologues two major components monoubiquitination machinery: UBIQUITIN-CONJUGATING ENZYME2 (NbUBC2) and HISTONE MONOUBIQUITINATION1 (NbHUB1)...
Significance Tomato leaf curl New Delhi virus (ToLCNDV) infection causes severe losses in tomato yield worldwide. Lack of information on resistance ( R ) genes against ToLCNDV has considerably retarded the pace crop improvement this rapidly spreading pathogen. Here, we report an effective defense strategy deployed by a resistant cultivar ToLCNDV. It employs Sw5a (R gene) that recognizes AC4 protein (viral effector) to restrict spread. At transcriptional level, sly-miR159-SlMyb33 module been...
The biological and molecular properties of Tomato leaf curl Gujarat virus from Varanasi, India (ToLCGV-[Var]) were characterized. ToLCGV-[Var] could be transmitted by grafting through whitefly transmission in a persistent manner. full-length genome DNA-A DNA-B was cloned pUC18. Sequence analysis revealed that (AY190290) is 2,757 bp (AY190291) 2,688 length. infect cause symptoms tomato, pepper, Nicotiana benthamiana, N. tabacum when partial tandem dimeric constructs co-inoculated particle...
Tomato leaf curl New Delhi virus (ToLCNDV) infection causes significant yield loss in tomato. The availability of a conventional tolerance source against this is limited To understand the molecular mechanism tomato, abundance viral genomic replicative intermediate molecules and virus-directed short interfering RNAs (siRNAs) by host plant naturally tolerant cultivar H-88-78-1 susceptible Punjab Chhuhara at different time points after agroinfection was studied. We report that less may have...
Abstract Background Emerging whitefly transmitted begomoviruses are major pathogens of vegetable and fibre crops throughout the world, particularly in tropical sub-tropical regions. Mutation, pseudorecombination recombination driving forces for emergence evolution new crop-infecting begomoviruses. Leaf curl disease field grown radish plants was noticed Varanasi Pataudi region northern India. We have identified characterized two distinct monopartite associated beta satellite DNA causing leaf...
Geminivirus disease complexes potentially interfere with plants physiology and cause disastrous effects on a wide range of economically important crops throughout the world. Diverse geminivirus betasatellite associations exacerbate epidemic threat for global food security. Our previous study showed that βC1, pathogenicity determinant betasatellites induce symptom development by disrupting ultrastructure function chloroplasts. Here we explored betasatellite-virus-chloroplast interaction in...
RNA silencing is an integral part of the cellular defense mechanisms in plants that act against virus infection. However, specific role and interplay between host components during recovery from geminivirus infection remains unknown. Hence, this study we aimed to examine mechanism behind host-specific Nicotiana tabacum infected with Tomato leaf curl Gujarat (ToLCGV). Unlike New Delhi (ToLCNDV), ToLCGV resulted symptom remission N. tabacum, found was mainly due cross-talk pre-coat protein...
Dysregulation of the immune system is a contributing factor in progression Alzheimer’s Disease (AD), likely by increased vascular inflammation triggered brain or peripheral inflammation. Our research has demonstrated that neutrophils play role causing hypoperfusion adhering to and obstructing blood vessels, as seen both mouse models for patients with AD. Notably, protein glycosylation membrane proteins essential regulating adhesion properties cells vasculature. Here, we utilize lectin blots...
