The family Luteoviridae consists of three genera: Luteovirus, Enamovirus, and Polerovirus. The genus Polerovirus contains 32 virus species. All are transmitted by aphids and can infect a wide variety of crops from cereals and wheat to cucurbits and peppers. However, little is known about how this wide range of hosts and vectors developed. In poleroviruses, aphid transmission and virion formation is mediated by the coat protein read-through domain (CPRT) while silencing suppression and phloem limitation is mediated by Protein 0 (P0)—a protein unique to poleroviruses. P0 gives poleroviruses a great advantage amongst plant viruses and diversifies polerovirus species, but the …

The CDC has classified antibiotic resistance as the biggest health challenge of our era; every year 2 million lives are impacted and even lost due to resistant bacteria. Bacteriophages provide an alternative route to fighting infections that does not further the development of antibiotic resistance among bacterial species. A bacteriophage replicates inside a bacterial cell and then causes that cell to lyse, an event that kills the bacterial host. However, some phage can integrate their genomes into the host chromosome without causing lysis. The HHMI SEA-PHAGES program has generated a collection of bacteriophage that infect Actinobacteria species. Over 13,000 phages …

Maize lethal necrosis is an intense viral disease spreading across sub-Saharan Africa. Maize is the staple crop grown in sub-Saharan Africa, but most crops infected with maize lethal necrosis will not survive to harvest. This causes immense economic hardship and starvation within the population. Maize lethal necrosis consists of a combination of two viruses, Maize chlorotic mottle virus (MCMV) and a virus from the genus potyvirus. In a recent study, a Maize yellow dwarf virus-RMV (MYDV-RMV)-like polerovirus, was repeatedly detected in plants with maize lethal necrosis. Poleroviruses have a silencing suppressor, P0 protein, and the mechanism of suppression is poorly …
