The fungus Cladosporium fulvum infects tomato and secretes various proteins that are recognized by resistant plants that respond with a hypersensitive response. Strains of the fungus that escape recognition by tomato are virulent. Resistance genes in tomato, either directly or indirectly involved in recognition of the fungal proteins, encode extracellular membrane-anchored, leucine-rich repeat proteins, which occur in gene clusters. Much progress has been made in our understanding of the evolution of recognitional specificities in the host plant.
番茄叶霉病菌会感染番茄，并分泌多种蛋白质，这些蛋白质会被抗性植物识别，引发过敏反应。无法被番茄识别的病菌菌株具有毒性。番茄中的抗性基因，直接或间接参与对真菌蛋白质的识别，编码细胞外膜锚定的富含亮氨酸重复序列的蛋白质，这些基因成簇存在。我们对寄主植物识别特异性的进化有了很多了解。
