In plant pathology, a lesion refers to a localized area of damage or abnormality on a plant's tissue, often resulting from disease, insect infestation, or environmental stress. Lesions can manifest as spots, blights, or cankers, and they often indicate the presence of pathogens such as fungi, bacteria, or viruses. The appearance and severity of lesions can significantly impact a plant's health, growth, and overall yield. Monitoring and managing lesions is crucial for effective plant disease management.

What do you mean by local lesion host in case of a plant?

A local lesion host in plants refers to a plant species that exhibits localized symptoms, such as lesions or spots, when infected by a pathogen, typically a virus or fungus. Unlike systemic hosts, where the pathogen spreads throughout the plant, local lesion hosts confine the infection to specific areas, allowing for the observation of distinct symptoms. This characteristic is often utilized in plant pathology for studying pathogen behavior and host responses, as it provides a clear indication of infection without widespread damage to the entire plant.

Pathology reports are not prepared when lesions?

Pathology reports are not prepared when lesions are deemed benign and do not require further investigation or when they are too small to warrant analysis. Additionally, if a lesion is excised but not sent for pathological evaluation, or if the sample is insufficient for diagnosis, a pathology report will not be generated. In some cases, clinical judgment may lead to the decision that further testing is unnecessary.
