Canker Stain of Plane Trees: An Increasing Threat to Urban and Natural Forests in the Mediterranean Basin (and Beyond)

This lecture addresses the growing threat posed by canker stain of plane trees, caused by the fungus Ceratocystis platani. Once introduced, the pathogen spreads rapidly through wounds, contaminated tools, root grafts, and water flows, causing severe decline and death of infected trees. The talk examines the disease’s expanding distribution across the Mediterranean Basin and its emergence in new regions, highlighting its significant impact on both urban avenues lined with plane trees and natural riparian forests. Emphasis is placed on early detection, strict sanitation measures, and coordinated biosecurity strategies to slow its spread and protect valuable plane tree populations.

High-Technology Methods in Forest Pathology: DNA Sequencing and Phenomics

This lecture introduces advanced technological methods used in modern forest pathology, focusing on DNA sequencing and phenomics. It explains how molecular tools enable precise identification of pathogens and improve understanding of their genetic diversity, evolution, and spread. The talk also highlights phenomics approaches—high-throughput imaging and data analysis techniques that assess disease symptoms, host responses, and pathogen interactions at scale. Together, these technologies enhance diagnostic accuracy, support early detection, and strengthen forest health monitoring and research.
