Identification and functional characterization of effector proteins from the fungal soil-borne pathogens Verticillium dahliae and Rosellinia necatrix

Summary

Crop production is constantly threatened by plant diseases caused by pathogens and pests. To understand such plant diseases, the molecular basis of plant-pathogen interactions has received much attention. To establish disease, during host ingress plant pathogenic microbes secrete effector molecules that promote host colonization. Effectors target various crucial components of host physiology, including immune responses. However, more recently it has been shown that some effectors can modulate root microbiota compositions to facilitate host colonization. The research focus on the molecular interactions between plants and soil-borne pathogens Verticillium dahliae and Rosellinia necatrix. These fungi secrete proteins called effectors, which help them colonize the host plant. This research show how certain effectors contribute to disease development. Additionally, how some of these effectors can influence the composition of root microbiota, aiding in the pathogen's colonization process. Understanding these mechanisms is crucial for developing strategies to protect crops from diseases, ultimately enhancing agricultural productivity.
