Journal ArticleDOI

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
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

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.
Journal ArticleDOI
Differential response of diverse solanaceous hosts to tomato leaf curl New Delhi virus infection indicates coordinated action of NBS-LRR and RNAi-mediated host defense.
TL;DR: It is suggested that the expression of host defense responses determines the level of ToLCNDV accumulation and degree of symptom development, and the viral DNA level was concurrent with symptom severity.
Journal ArticleDOI
Tobacco RNA-dependent RNA polymerase 1 affects the expression of defence-related genes in Nicotiana benthamiana upon Tomato leaf curl Gujarat virus infection.

TL;DR: This study suggests that reduced expression of subunit-7 of CSN complex and WRKY6, and increased expression of USPA-like protein might be linked with the reduced susceptibility of NtRDR1-transgenic N. benthamiana plants to ToLCGV.
