Foveaviruses

Foveaviruses are a genus of plant-infecting viruses belonging to the family Geminiviridae. These viruses are characterized by their single-stranded DNA genomes, which are typically circular and bipartite, meaning they are divided into two separate DNA molecules. Foveaviruses are transmitted by insect vectors, primarily leafhoppers, which acquire the virus by feeding on infected plants and then transmit it to healthy plants during subsequent feeding.

The name "foveavirus" derives from the Latin word "fovea," meaning pit or depression, referring to the characteristic symptoms observed in infected plants. These symptoms can include stunting, leaf curling, yellowing, and the development of necrotic lesions or pit-like formations on the leaves and stems. The specific symptoms vary depending on the virus species and the host plant. Foveaviruses can infect a wide range of plant species, including important agricultural crops, potentially causing significant economic losses.

Research into foveaviruses is ongoing, focusing on understanding their replication cycle, transmission mechanisms, and host interactions. Developing effective control strategies is also a key area of research, often involving integrated pest management approaches that target the insect vectors and the use of resistant plant varieties. Early detection and diagnosis are crucial for managing foveavirus outbreaks in agricultural settings.
