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.

Attaining the Promise of Geminivirus-Based Vectors in Plant Genome Editing [PDF]

Viruses
Over the last 40 years, several studies have provided evidence demonstrating that viral vectors can result in effective gene targeting/insertions in a host’s genome.

SGS3 Cooperates with RDR6 in Triggering Geminivirus-Induced Gene Silencing and in Suppressing Geminivirus Infection in Nicotiana Benthamiana

Viruses, 2017
RNA silencing has an important role in defending against virus infection in plants. Plants with the deficiency of RNA silencing components often show enhanced susceptibility to viral infections.

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 ...

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.

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.

Efficient production of functional cholera toxin B subunit using geminiviral replicons in Nicotiana benthamiana [PDF]

Frontiers in Bioengineering and Biotechnology
The cholera toxin B subunit (CTB) has the potential to be a carrier molecule and an effective adjuvant for mucosal vaccines because of its ability to enhance immune responses to antigens. CTB proteins have been expressed in plant-based expression systems.

Stabilisation of Tomato Yellow Leaf Curl China Virus Infectious Clones Through Micro-Homology Mediated End Joining. [PDF]

Plant Biotechnol J
ABSTRACT Tomato yellow leaf curl China virus (TYLCCNV) is a major agricultural pathogen and primary model for circular single‐stranded DNA (cssDNA) virus studies. The infectious clones of TYLCCNV and other cssDNA viruses are usually constructed as two tandem copies of the small viral genomes in Agrobacterium‐mediated T‐DNA vectors.

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.
