Whole‐plant microbiome profiling reveals a novel geminivirus associated with soybean stay‐green disease

Plant Biotechnology Journal, 2022
Summary Microbiota colonize every accessible plant tissue and play fundamental roles in plant growth and health. Soybean stay‐green syndrome (SGS), a condition that causes delayed leaf senescence (stay‐green), flat pods and abnormal seeds of soybean, has

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 ...

Highly Efficient Genome Editing Using Geminivirus-Based CRISPR/Cas9 System in Cotton Plant

Cells, 2022
Upland cotton (Gossypium hirsutum), an allotetraploid, contains At- and Dt- subgenome and most genes have multiple homologous copies, which pose a huge challenge to investigate genes’ function due to the functional redundancy.

CRISPR/Cas9 Targeted Editing of Genes Associated With Fungal Susceptibility in Vitis vinifera L. cv. Thompson Seedless Using Geminivirus-Derived Replicons

Frontiers in Plant Science, 2021
The woody nature of grapevine (Vitis vinifera L.) has hindered the development of efficient gene editing strategies to improve this species. The lack of highly efficient gene transfer techniques, which, furthermore, are applied in multicellular explants ...

Olea Europaea Geminivirus: A Novel Bipartite Geminivirid Infecting Olive Trees

Viruses, 2021
In 2014, high-throughput sequencing of libraries of total DNA from olive trees allowed the identification of two geminivirus-like contigs. After conventional resequencing of the two genomic DNAs, their analysis revealed they belonged to the same viral ...

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

Selective autophagic receptor NbNBR1 prevents NbRFP1-mediated UPS-dependent degradation of βC1 to promote geminivirus infection

PLoS Pathogens, 2021
Autophagy is an evolutionarily conserved, lysosomal/vacuolar degradation mechanism that targets cell organelles and macromolecules. Autophagy and autophagy-related genes have been studied for their antiviral and pro-viral roles in virus-infected plants ...

Positive selection and intrinsic disorder are associated with multifunctional C4(AC4) proteins and geminivirus diversification

Scientific Reports, 2021
Viruses within the Geminiviridae family cause extensive agricultural losses. Members of four genera of geminiviruses contain a C4 gene (AC4 in geminiviruses with bipartite genomes).

Geminivirus Betasatellite-Encoded βC1 Protein Exhibits Novel ATP Hydrolysis Activity That Influences Its DNA-Binding Activity and Viral Pathogenesis

Journal of Virology, 2021
Most satellites influence the pathogenesis of their helper viruses. Here, we characterized the novel molecular function of βC1, a nonstructural pathogenicity determinant protein encoded by a betasatellite.

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.
