Plant viruses are infectious agents that specifically target and infect plants, causing a variety of diseases and symptoms such as stunted growth, discoloration, and reduced yield. These viruses are typically transmitted through vectors such as insects, fungi, nematodes, and through mechanical means like pruning tools or contaminated seeds. Research in the area of plant viruses focuses on understanding the molecular mechanisms of virus-plant interactions, developing methods for virus detection and diagnosis, and exploring strategies for controlling virus spread and infection in crops. This research is crucial for maintaining plant health and ensuring sustainable agriculture practices.
