Geminivirus Resistance: A Minireview [PDF]

Frontiers in Plant Science, 2020
A continuing challenge to crop production worldwide is the spectrum of diseases caused by geminiviruses, a large family of small circular single-stranded DNA viruses.

Haplotype-resolved genomes of geminivirus-resistant and geminivirus-susceptible African cassava cultivars [PDF]

BMC Biology, 2019
Background Cassava is an important food crop in tropical and sub-tropical regions worldwide. In Africa, cassava production is widely affected by cassava mosaic disease (CMD), which is caused by the African cassava mosaic geminivirus that is transmitted ...

Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection. [PDF]

New Phytol
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

A TIR-NLR gene from Arabidopsis Pla-1 confers resistance to geminivirus infection. [PDF]

Plant J
SUMMARY Geminiviruses are single‐stranded DNA viruses that infect many plant species and cause serious losses in agronomically important crops. An earlier study showed that the Arabidopsis thaliana ecotype Pla‐1 is resistant to infection by diverse geminivirus species and mapped the major resistance locus Geminivirus Resistance of Pla‐1 1 (GRP1) to ...

Development of Modular Geminivirus-Based Vectors for High Cargo Expression and Gene Targeting in Plants. [PDF]

Plant Biotechnol J
ABSTRACT Viral vectors can be useful tools for expressing recombinant proteins as well as delivering gene‐editing machinery. Despite their utility, the development and subsequent optimisation of these tools is often a difficult and tedious process.

Virus-Inducible Activation of Hypersensitive Response Confers Broad-Spectrum Resistance to Diverse Viruses in Plants. [PDF]

Mol Plant Pathol
Using a virus‐inducible promoter to drive the expression of the Avr4/Cf‐4 gene pair can trigger a hypersensitive response upon viral infection, which confers plants broad‐spectrum resistance to geminiviruses. ABSTRACT The hypersensitive response (HR) is a powerful plant defence mechanism that restricts pathogen spread through localised cell death ...

Engineering Conditional Transgene Expression in Nicotiana benthamiana. [PDF]

Plant Biotechnol J
ABSTRACT Nicotiana benthamiana has emerged as a premier plant biofactory for recombinant protein and metabolite production due to its high metabolic versatility, ease of cultivation and permissiveness to transient expression vectors. However, challenges such as transgene silencing, low yields and metabolic toxicity limit its scalability. Synthetic gene

Interactions between geminivirus replication proteins [PDF]

Journal of Virology, 1996
Geminiviruses are small DNA viruses that replicate in the nuclei of infected plant cells. The closely related geminiviruses tomato golden mosaic virus and bean golden mosaic virus each encode a protein, AL1, that catalyzes the initiation of rolling-circle replication.

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).
