Researchers discovered over 47,000 endogenous viral elements in plant genomes, revealing the wide range of hosts infected by Caulimoviridae viruses. The study also found 35 previously undescribed taxonomic clusters, including a new clade in conifers.
A plant virus, cowpea mosaic virus (CPMV), has shown promise as a low-cost and potent cancer immunotherapy. CPMV stimulates type I, II, and III interferons, which have well-known anti-cancer properties, and activates toll-like receptor 7 to prime antiviral and anti-tumor immune responses.
The Phytovirome Focus Issue addresses fundamental and translational aspects of phytovirome science, highlighting the transformative role of high-throughput sequencing technologies. Researchers discovered a remarkable diversity of viruses in plants, with complex communities interacting with hosts in both pathogenic and beneficial ways.
Researchers are tackling the problem from multiple perspectives, bringing in interdisciplinary expertise to understand the virus on a fundamental level. The project aims to inform the general public of the challenges that plant viruses and vectors present to global food and nutritional security.
Yiliang Ding's pioneering work on RNA structure and function has led to breakthroughs in plant virus treatment, increasing structural understanding of this crucial molecule. Her award-winning research has the potential to drive scientific innovation in agriculture and human health.
Researchers at the University of California San Diego have developed nanoparticles that can deliver pesticide molecules to soil depths previously unreachable, targeting root-damaging nematodes. The technology holds promise for enhancing treatment effectiveness while minimizing costs and environmental toxicity.
A new combination therapy using a plant virus and an antibody activates natural killer cells to target and destroy cancer cells. The therapy eliminates all tumors and prevents their recurrence, resulting in 100% survival in mouse models of colon cancer.
A team of researchers has discovered that cowpea mosaic virus, when injected into a tumor, triggers a powerful immune response, preventing cancer recurrence. The unique protein shell and RNA structure of the virus activate toll-like receptors, leading to increased cytokine production and a prolonged anti-cancer response.
Researchers found that half of Pseudomonas syringae strains benefited from the presence of aphids, but only the honeydew itself boosted bacterial populations. The study suggests using this phenomenon to develop alternative pest control methods.
A new viral disease caused by Tomato brown rugose fruit virus (ToBRFV) has emerged, threatening global tomato production. ToBRFV overcomes the durable Tm-2² resistance gene, which had remained unbroken for over half a century.
Researchers developed a treatment using cowpea mosaic virus nanoparticles that target lung tumors, slowing tumor growth and preventing cancer spread. The treatment showed efficacy against aggressive cancer cell lines and may offer protection to patients at high risk of metastatic disease.
Researchers at the University of California - San Diego have developed COVID-19 vaccine candidates made from plant viruses and bacteriophages, which can be stored and shipped without refrigeration. These vaccines trigger high production of neutralizing antibodies in mice, offering a potential solution for global distribution efforts.
The new database covers 219 pathogens that infect plants in Brazil, including many agriculturally important species. It presents information on diseases caused by the viruses and their occurrence in native, cultivated, and ornamental plants.
The Fundamental Aspects of Plant Viruses focus issue in New Phytopathology emphasizes recent breakthroughs in understanding plant viruses and their impact on agriculture. The issue features studies on virus-host and vector interactions, replication, and pathogenicity, shedding light on disease development and horizontal transmission.
Recent advances suggest that plant viruses are not just disease-causing entities, but can also play a significant role in the functioning of diverse ecosystems. Viruses have been found to be present in humans, with around 100,000 pieces of viral DNA elements making up 8% of our genome.
Aphids and insect-infecting viruses like PLRV and MpDNV transmit crop damage worth billions annually. Researchers found a cooperative relationship between the two, increasing the likelihood of viral spread.
A study by international scientists found that viruses cluster in genetically similar organisms and agricultural land, leading to a higher prevalence of viral infections. The research also reveals a vast number of viruses in the natural compartment, which can inform the emergence of plant diseases.
The domestication of wild plants for biofuel use can increase virus pressure in crop areas unless mitigated. Perennial plants in nature grow slower but are better equipped to fight off viruses, whereas annual plants can serve as 'amplifiers' producing lots of viruses and insects.
Researchers at Vanderbilt University have obtained detailed information about the structure of flexible filamentous viruses, responsible for over half of all virus damage. The findings could lead to new ways to protect crops from these viruses and potentially use them as agents of biotechnology.
