Abstract

Monopustule isolates of wheat, oats and barley rust pathogens reproduced under different environmental conditions were used to infect experimental samples of these crops. Differences in the types of reactions after infection of one plant genotype with one pathogen genotype reproduced at different temperatures, as well as in the presence of potassium chloride, ammonium nitrate and maleic acid hydrazide indicate the impossibility of explaining the phenomena of plant–pathogen interaction within the framework of Flor’s classical gene-for-gene theory. Each gene of the host resistance corresponds to several complementary virulence genes, or to several different alleles of one same gene for virulence.

Flor关于谷物幼苗与锈病病原体相互作用现象的基因对基因理论的修订

摘要

在不同环境条件下繁殖的小麦、燕麦和大麦锈病病原体的单脓疱分离物被用来感染这些作物的实验样品。一种植物基因型与在不同温度下繁殖的一种病原体基因型感染后反应类型的差异，以及在氯化钾、硝酸铵和马来酰肼的存在下，表明不可能解释植物-病原体相互作用的现象。弗洛尔经典基因对基因理论的框架。宿主抗性的每个基因对应于几个互补的毒力基因，或对应于同一个毒力基因的几个不同等位基因。
