Insights into Emerging Begomovirus–Deltasatellite Complex Diversity: The First Deltasatellite Infecting Legumes

Biology, 2021
Begomoviruses and associated DNA satellites are involved in pathosystems that include many cultivated and wild dicot plants and the whitefly vector Bemisia tabaci. A survey of leguminous plants, both crops and wild species, was conducted in Venezuela, an

Endogenous caulimovirid sequences are widespread in plant genomes [PDF]

, 2010
Endogenous sequences from members of the Caulimoviridae and Geminiviridae families have been identified in the genome of several plant species. They are thought to result from illegitimate recombination events and are generally replication-defective ...

A Shift in Begomovirus coheni Populations Associated With Tomato Yellow Leaf Curl Disease Infecting Tomato Cultivars in the Southeastern United States

Plant Pathology, Volume 74, Issue 5, Page 1277-1289, June 2025.
A shift in Begomovirus coheni populations associated with tomato yellow leaf curl disease (TYLCD) in tomato cultivars might facilitate the emergence of tomato yellow leaf curl virus‐Georgia (TYLCV‐GA) in natural conditions. ABSTRACT Tomato yellow leaf curl virus (TYLCV) is a major pathogen causing tomato yellow leaf curl disease (TYLCD), significantly ...

Attempts to identify Cassava Brown Streak Virus in western Democratic Republic of Congo [PDF]

, 2020
Open Access ArticleRoot necrosis similar to those of the cassava brown streak disease (CBSD) were observed on cassava in western provinces of the Democratic Republic of Congo (DR.Congo) in the early 2000’s. However molecular laboratory diagnosis were not

Plant viruses convergently target NPR1 with various strategies to suppress salicylic acid‐mediated antiviral immunity

Journal of Integrative Plant Biology, Volume 67, Issue 5, Page 1395-1412, May 2025.
Viral infection triggers monomerization and nuclear translocation of the salicylic acid receptor NONEXPRESSOR OF PATHOGENESIS‐RELATED GENES1 (NPR1) to activate pathogenesis‐related gene expression. Nevertheless, viruses have developed one or more proteins to target NPR1 and impair its functionality through mechanisms such as inducing its degradation ...
