plant-pathology
Plant pathology is the scientific study of plant diseases caused by pathogens and environmental conditions, encompassing disease identification, epidemiology, and management strategies. Understanding and controlling plant diseases is essential for maintaining food security and crop productivity, as pathogens can cause significant agricultural losses. By investigating disease mechanisms, resistance traits, and pathogen biology, plant pathologists develop evidence-based approaches to protect plants and support sustainable agriculture.

Researchers discovered 22 previously unknown plant viruses by mining public genetic databases. These viruses, found across 22 plant species, expand our understanding of viral diversity and may help develop better crop protection strategies against viral infections.
Identified 22 novel closteroviral viruses with 19 complete genomes and 3 partial genomes across 22 plant genera
Classified viruses into 5 known genera (Ampelovirus, Bluvavirus, Closterovirus, Olivavirus, Velarivirus) plus 4 potentially novel genera
Discovered unique viral features including the largest known closterovirid genome and ampeloviruses with RNA polymerase structures lacking ribosomal frameshifts
