Metagenomics reveals the structure of Mastrevirus-host interaction network within an agro-ecosystem. [PDF]
Abstract As highly pervasive parasites that sometimes cause disease, viruses are likely major components of all natural ecosystems. An important step towards both understanding the precise ecological roles of viruses and determining how natural communities of viral species are assembled and evolve is obtaining full descriptions of viral ...

Emerging Viral Threats in Rice: A Decade of Discovery and Implications for Crop Protection. [PDF]
ABSTRACT Rice viral diseases pose severe threats to global food security, with over 20 viruses identified in China alone. The advent of high‐throughput sequencing has accelerated the discovery of novel viruses in cultivated and wild rice, unveiling previously undetected threats.

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

Mastrevirus Rep and RepA Proteins Suppress de novo Transcriptional Gene Silencing. [PDF]
Transcriptional gene silencing (TGS) in plants is a defense mechanism against DNA virus infection. The genomes of viruses in the Geminiviridae family encode several TGS suppressors. In this study, we induced de novo TGS against the transgenic GFP gene encoding green fluorescent protein by expressing a hairpin-shaped self-complementary RNA corresponding

Viromes of Ten Alfalfa Plants in Australia Reveal Diverse Known Viruses and a Novel RNA Virus
Alfalfa plants in the field can display a range of virus-like symptoms, especially when grown over many years for seed production. Most known alfalfa viruses have RNA genomes, some of which can be detected using diagnostic assays, but many viruses of ...

A novel maize-infecting mastrevirus from La Réunion Island [PDF]
Despite extensive sampling, only one virus belonging to the genus Mastrevirus of the family Geminiviridae, maize streak virus (MSV), has until now been detected in maize with maize streak disease (MSD) symptoms. Here, we report for the first time a second, highly divergent, mastrevirus isolated from two maize plants displaying characteristic MSD-like ...

Abstract Rice yellow mottle virus (RYMV) is widespread in mainland Africa and adjoining islands but to date its occurrence in Zambia is unknown. In March 2022, field surveys were conducted in Luapula, Northern, Western and Eastern provinces of Zambia to determine the occurrence of RYMV and its genetic relationship with global isolates of the virus ...

Tools and targets: The dual role of plant viruses in CRISPR–Cas genome editing
Abstract The recent emergence of tools based on the clustered, regularly interspaced, short palindromic repeats (CRISPR) and CRISPR‐associated (Cas) proteins have revolutionized targeted genome editing, thus holding great promise to both basic plant science and precision crop breeding. Conventional approaches for the delivery of editing components rely

As the past is the key to the future, to understand community transformations and ecological interactions, we reconstructed ecosystem‐wide biotic composition (from viruses to megaherbivores) between glacials and interglacials from the Middle and Late Pleistocene at the Batagay megaslump, east Siberia.

CRISPR/Cas‐based tools for the targeted control of plant viruses
Plant viruses pose a major threat to global food security. In this review we provide an overview of the use and limitations of CRISPR/Cas‐based technology for resistance against DNA and RNA viruses in plants. Abstract Plant viruses are known to infect most economically important crops and pose a major threat to global food security.
