ALT Diagram illustrating key components of an ideal Plant/Forest Pathogen Model System, arranged in four quadrants around a central circle containing illustrations of various crops and forest trees. Each quadrant highlights essential criteria: Community and Resources (top left, blue background); Standardized Methods (top right, light green background); Experimental Feasibility (bottom left, pale yellow background); and Pathosystem Context (bottom right, light brown background). At the center, the title reads ‘Plant/Forest Pathogen Model System’, surrounded by illustrations of plants including herbaceous crops and trees, representing diverse host types.
