植物生理免疫不同于常规的通过杂交或生物技术导入抗性基因,或者如Kuc等报道的诱导抗病性。它是对植物生长发育的多种生态因子进行调控,进而启动或活化了植物体内尚未被认识的抗性基因,俾使那些原来表现高度感病的作物品种,经过生理免疫处理后,表达为免疫或高度抗病的现象。这在国内外文献上尚不多见,我们在进行小麦秆锈菌的毒力基因与小麦品种抗病基因的互作研究中,观察到这一植物生理免疫现象,简要报道如下; 供试小麦品种为对国内秆锈菌小种,不含任何已知抗性基因的小密穗(Little Club)和浙麦一号,以及
Physiological immunity differs from conventional introduction of resistance genes by crossing or biotechnology, or induction of disease resistance as reported by Kuc et al. It is a variety of ecological factors that regulate plant growth and development, and then start or activate the plant has not yet been recognized in the resistance genes, so that those originally highly susceptible crop varieties, after physiological immunization, expressed as immune Or highly disease-resistant. This literature is rare at home and abroad, we carry out wheat virulence genes and wheat disease resistance gene interaction study observed this plant physiological immune phenomenon, a brief report as follows; test wheat Varieties for the domestic races of Scutellaria stoloparis, Little Club, which contains no known resistance genes, and No 1 Zhemai, and
