Identification and characterization of a new geminivirus from soybean plants and determination of V2 as a pathogenicity factor and silencing suppressor

BMC Plant Biology, 2022
Background Soybean is one of the four major crops in China. The occurrence of viruses in soybean causes significant economic losses. Results In this study, the soybean leaves from stay-green plants showing crinkle were collected for metatranscriptomic ...

Geminiviruses and Plant Hosts: A Closer Examination of the Molecular Arms Race

Viruses, 2017
Geminiviruses are plant-infecting viruses characterized by a single-stranded DNA (ssDNA) genome. Geminivirus-derived proteins are multifunctional and effective regulators in modulating the host cellular processes resulting in successful infection.

Regulated nuclear trafficking of rpL10A mediated by NIK1 represents a defense strategy of plant cells against virus. [PDF]

PLoS Pathogens, 2008
The NSP-interacting kinase (NIK) receptor-mediated defense pathway has been identified recently as a virulence target of the geminivirus nuclear shuttle protein (NSP).

Silencing of a Germin-Like Protein Gene (CchGLP) in Geminivirus-Resistant Pepper (Capsicum chinense Jacq.) BG-3821 Increases Susceptibility to Single and Mixed Infections by Geminiviruses PHYVV and PepGMV

Viruses, 2015
Germin-like proteins (GLPs) are encoded by a family of genes found in all plants, and in terms of function, the GLPs are implicated in the response of plants to biotic and abiotic stresses.

ty-5 Confers Broad-Spectrum Resistance to Geminiviruses

Viruses, 2022
The selection of resistant crops is an effective method for controlling geminivirus diseases. ty-5 encodes a messenger RNA surveillance factor Pelota with a single amino acid mutation (PelotaV16G), which confers effective resistance to tomato yellow leaf

A Bipartite Geminivirus Infecting Tomatoes in Cuba [PDF]

Plant Disease, 1997
Whitefly-transmitted geminiviruses have increased in their distribution and importance during the last decade, apparently due to a wider distribution of their vector Bemisia tabaci (Gennadius). In Cuba, symptoms of geminivirus disease have been observed since the early 1990s.

gb4gv: A genome browser for geminivirus

PeerJ, 2017
Background: Geminivirus (family Geminiviridae ) is a prevalent plant virus that imperils agriculture globally, causing serious damage to the livelihood of farmers, particularly in developing countries. The virus evolves rapidly, attributing to its single-stranded genome propensity,

Functional Domains of a Geminivirus Replication Protein [PDF]

Journal of Biological Chemistry, 1997
Tomato golden mosaic virus, a member of the geminivirus family, has a single-stranded DNA genome that is replicated and transcribed in infected plant cells through the concerted action of viral and host factors. One viral protein, AL1, contributes to both processes by binding to a directly repeated, double-stranded DNA sequence located in the ...

Geminivirus Resistance in Transgenic Tobacco Expressing Mutated BC1 Protein

Molecular Plant-Microbe Interactions, 1997
Tobacco explants were transformed by Agrobacterium-mediated transformation with sense and antisense constructs of the movement protein genes (BC1 and BV1) of tomato mottle geminivirus (TMoV).
