Genetic diversity and phylogeography of cassava mosaic geminiviruses in Madagascar. [S02-12] [PDF]

, 2012
Cassava mosaic disease (CMD) caused by cassava mosaic geminiviruses (CMGs, Geminiviridae) is a major threat on cassava production throughout Africa. In Madagascar, severe symptoms with high prevalence of CMD were observed.

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 ...

First Report of Cabbage leaf curl virus (Family Geminiviridae) in Georgia

Plant Disease, 2001
Cabbage and collard greens were inflicted with a previously undescribed virus-like disease during the fall 2000. Symptoms on leaves were yellow spots, vein clearing, mosaic, curling, and puckering. Symptomatic plants were widespread in Brooks, Colquitt, Grady, and Pierce counties in Georgia.

Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]

PLoS ONE, 2018
When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...

Geminivirus–Host Interactions: Action and Reaction in Receptor-Mediated Antiviral Immunity

Viruses, 2021
In plant−virus interactions, the plant immune system and virulence strategies are under constant pressure for dominance, and the balance of these opposing selection pressures can result in disease or resistance.

The viral content ratio between abdomen and head is informative of the relative efficiency with which Bemisia tabaci populations transmit begomoviruses. [P.12] [PDF]

, 2015
Begomoviruses (family Geminiviridae) are transmitted by the whitefly Bemisia tabaci in a circulative non propagative manner. B. tabaci is a species complex composed of at least 24 morphocryptic species which differ in host range, insecticide resistance ...

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 ...
