Differential Shape of Geminivirus Mutant Spectra Across Cultivated and Wild Hosts With Invariant Viral Consensus Sequences

Frontiers in Plant Science, 2018
Geminiviruses (family Geminiviridae) possess single-stranded circular DNA genomes that are replicated by cellular polymerases in plant host cell nuclei. In their hosts, geminivirus populations behave as ensembles of mutant and recombinant genomes, known ...

Geminiviruses employ host DNA glycosylases to subvert DNA methylation-mediated defense

Nature Communications, 2022
Plants tightly regulate DNA methylation to regulate gene expression. Here, the authors show that the tomato yellow leaf curl China virus βC1 protein interacts with plant DNA glycosylases to promote demethylation of viral DNA and promote virulence.

Emerging evidence of seed transmission of begomoviruses: implications in global circulation and disease outbreak

Frontiers in Plant Science
Begomoviruses (family Geminiviridae) are known for causing devastating diseases in fruit, fibre, pulse, and vegetable crops throughout the world. Begomoviruses are transmitted in the field exclusively through insect vector whitefly (Bemisia tabaci), and ...

Functional Analysis of Gene-Silencing Suppressors from Tomato Yellow Leaf Curl Disease Viruses

Molecular Plant-Microbe Interactions, 2012
Tomato yellow leaf curl disease (TYLCD) is caused by a complex of phylogenetically related Begomovirus spp. that produce similar symptoms when they infect tomato plants but have different host ranges.

The epigenetic landscape of plant defense: Unlocking nature's toolkit for new plant protection

New Plant Protection, EarlyView.
This review examines how epigenetic mechanisms regulate plant immune gene activation, repression, and priming, then links these natural regulatory layers to emerging epigenetic editing, discussing their potential for precise, heritable crop protection and the challenges.
