Webinar Summary

Acidovorax citrulli is the causal agent of bacterial fruit blotch (BFB), a serious disease of cucurbits, and mainly of watermelon and melon. Despite the agricultural importance of BFB, still little is known about basic aspects of the disease. As many Gram-negative pathogenic bacteria, A. citrulli utilizes a type III secretion system (T3SS) to deliver virulence, type III effectors (T3Es) into the host cell. A. citrulli possess at least ~60 known T3E genes, placing this species among the richest pathogenic bacteria in terms of T3E arsenal’s size. One of the goals of my lab is to identify T3Es that significantly contribute to virulence and adaptation of this pathogen to different cucurbit crops. While the large amount of T3Es and the subtle phenotype of most of them challenge this goal, I believe we are making progress in optimization of the molecular tools that will enable breakthroughs in the field.

Speaker

Saul Burdman is a Professor of Plant Pathology at the Faculty of Agriculture, Food and Environment of the Hebrew University, Israel. His career has focused primarily on basic and applied aspects of bacterial plant diseases and the use of beneficial bacteria for plant growth promotion. Burdman is an internationally recognized scientist in investigation of bacterial fruit blotch disease of cucurbits, caused by Acidovorax citrulli. Together with Ron Walcott (University of Georgia) he edited the book "Plant-Pathogenic Acidovorax Species”, published by APS Press.

Burdman teaches several undergraduate and graduate courses in Plant Pathology and Phytobacteriology at the Hebrew University. He has served as Coordinator of Program Studies in Agroecology and Plant Health and as Head of the Department of Plant Pathology and Microbiology at the Hebrew University. He served as President of the Israeli Phytopathological Society from 2019 to 2022, and is the current Dean of the Faculty of Agriculture, Food and Environment.




About the Advances in Phytobacteriology​ Series
