Toxin and elicitor: a comparative analysis of functions and pathological roles of cell death inducers from plant pathogenic fungi

植物病原菌的毒素和激发子似乎分别作为毒力因子和无毒因子发挥作用。然而，这两个因子作为植物细胞程序性死亡的诱导剂具有共同的作用。在该项目中，我们证明了寄主植物中由寄主特有的毒素和激发子诱导的细胞死亡导致了坏死型植物病原体侵染过程中的亲和反应。毒素和激发子都可能在寄主-坏死性病原菌相互作用中起致病因子的作用。此外，这些结果表明，这些因素引发的细胞死亡级联可能是由每个因素诱导的不同信号通路介导的。

Toxins and elicitors from plant pathogens appear to be functional as virulence and avirulence factors, respectively. While, both factors have a common role as an inducer for programmed cell death in plant cells. In the project, we showed evidence that cell death in a host plant induced by both host-specific toxins and elicitors leads to the compatible reaction in the infection process of necrotrophic plant pathogen. Both the toxin and the elicitor might act as pathogenicity factors in host-necrotrophic pathogen interactions. In addition, the results indicate that cell death cascades triggered by those factors might be mediated by different signaling pathways induced by each factor.
