Geminivirus Strain Demarcation and Nomenclature
Geminivirus taxonomy and nomenclature is growing in complexity with the number of genomic sequences deposited in sequence databases. Taxonomic and nomenclatural updates are published at regular intervals (Fauquet et al. in Arch Virol 145:1743–1761, 2000, Arch Virol 148:405–421, 2003).

Silencing suppression by geminivirus proteins
RNA silencing is an RNA-directed gene regulatory system that is present in a wide range of eukaryotes, and which functions as an antiviral defense in plants. Silencing pathways are complex and partially overlapping, but at least three basic classes can be distinguished: cytoplasmic RNA silencing (or post-transcriptional gene silencing; PTGS) mediated ...

ToLCNDV is typically transmitted by the whitefly Bemisia tabaci, but the efficiency of transmission varies among different cryptic species. The retention and circulation of viruses in insect vectors are crucial determinants of successful transmission to new plants.

A Population Genetics Perspective on Geminivirus Infection [PDF]
ABSTRACT The selective accumulation of both DNA components of a bipartite geminivirus, Abutilon mosaic virus, was recorded during early systemic infection of Nicotiana benthamiana plants. Purified nuclei were diagnosed for viral DNA using hybridization specific for DNA A or DNA B to

ABSTRACT Cassava is a crucial staple crop in Africa, but its productivity is increasingly threatened by the worsening impacts of drought caused by climate change. To address this challenge, an integration of “omics” and genome editing technologies has emerged as indispensable tools for understanding the complex mechanisms that govern cassava's response

Begomoviruses infecting common beans (Phaseolus vulgaris L.) in production areas in Cuba
Viral diseases caused by begomoviruses are economically important for their depressing impact on common bean production in Cuba. Mayabeque is a Cuban province where this crop is significantly grown and affectations by Bean golden yellow mosaic virus ...
