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 ...

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

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 ...

Identification of Tomato Proteins That Interact With Replication Initiator Protein (Rep) of the Geminivirus TYLCV

Frontiers in Plant Science, 2020
Geminiviruses are plant-infecting DNA viruses that reshape the intracellular environment of their host in order to create favorable conditions for viral replication and propagation.

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.

RepA Enhances Plant Resistance to Citrus Chlorotic Dwarf-Associated Virus by Transcriptionally Activating ClAOS. [PDF]

Mol Plant Pathol
We revealed a novel role for CCDaV‐RepA as a nuclear transcriptional regulator and citrus utilise this function of RepA to activate ClAOS, which is a key gene that limits the rate of jasmonic acid (JA) synthesis. This enhances JA‐mediated defence response to CCDaV in lemon.

Geminivirus-Derived Vectors as Tools for Functional Genomics

Frontiers in Microbiology, 2022
A persistent issue in the agricultural sector worldwide is the intensive damage caused to crops by the geminivirus family of viruses. The diverse types of viruses, rapid virus evolution rate, and broad host range make this group of viruses one of the ...

Small but mighty: Functional landscape of the versatile geminivirus-encoded C4 protein

PLoS Pathogens, 2021
The fast-paced evolution of viruses enables them to quickly adapt to the organisms they infect by constantly exploring the potential functional landscape of the proteins encoded in their genomes.
