作为信号介导植保素合成等而直接介入或启动植物过敏性反应。 现初步认为“氧化突发”可能是细胞水平上植物对付病原菌侵染的第一步。

It has been assumed that "oxidative burst" may serve as a first line of plant defense against the invading pathogen at cell level.

因此，不论用病原菌直接侵染还是用生物诱导子外源处理植物生体，都能有效诱导植保素的生成。

Therefore, infected by pathogen directly and treated with biotic elicitors both can induce the phytoalexins effectively.
