宿主选择性毒素及其在植物病害中的作用

植物的某些破坏性病害与一些具有特殊性质的毒素有关。某些寄生真菌产生低分子量的毒素，选择性地影响寄主植物;非寄主植物是耐受的。这些毒素具有不同的结构，包括环状肽和线性聚酮醇。遗传和其他数据表明，对每种真菌的抗性都是基于对其毒素的耐受性。同样的真菌基因控制毒素的产生和致病能力。尽管有一种毒素选择性地影响线粒体，但对毒性作用知之甚少。植物细胞膜受到影响;这可能使真菌在组织中定居。抗性细胞可能缺乏毒素受体位点。
Toxins with unusual characteristics are involved in some destructive diseases of plants. Certain parasitic fungi produce toxins of low molecular weight that selectively affect the host plant; nonhosts are tolerant. These toxins have diverse structures, including cyclic peptides and linear polyketols. Genetic and other data show that resistance to each fungus is based on tolerance to its toxin. The same fungal genes control toxin production and ability to cause disease. Little is known about toxic action, although one toxin selectively affects mitochondria. Plant cell membranes are affected; this may allow the fungus to colonize tissues. Resistant cells may lack toxin receptor sites.
