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.

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.

REPercussions: how geminiviruses recruit host factors for replication

Frontiers in Microbiology, 2023
Circular single-stranded DNA viruses of the family Geminiviridae encode replication-associated protein (Rep), which is a multifunctional protein involved in virus DNA replication, transcription of virus genes, and suppression of host defense responses ...

Construction and Biological Characterization of Papaya Leaf Curl Guangdong Virus Infectious cDNA Clone. [PDF]

Microb Biotechnol
Viral diseases are important diseases on cash crops such as passion fruit, among which PaLCuGDV is one of the more severe in recent years. We constructed an infectious clone of PaLCuGDV for the first time and confirmed its infectivity through biological assays.

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.

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 ...

Requirements for the Packaging of Geminivirus Circular Single-Stranded DNA: Effect of DNA Length and Coat Protein Sequence

Viruses, 2020
Geminivirus particles, consisting of a pair of twinned isometric structures, have one of the most distinctive capsids in the virological world. Until recently, there was little information as to how these structures are generated.

Geminiviruses Associated with the Weed Species Ageratum conyzoides, Centipeda minima, Porophyllum ruderale, and Spilanthes iabadicensis from Java, Indonesia

Microbiology Indonesia, 2012
Geminivirus has a wide host range including cultivated plants and weeds. Infected weeds may play an important role in disease epidemic. Unfortunately, little is known about weeds species that may serve as alternative host for Geminivirus.

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 ...
