Toxin vs. elicitor : a comparative analysis of function and evolution 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致病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。在这里，我们提供了由寄主特异的AAL-毒素和INF1激发子诱导的寄主植物细胞死亡导致了坏死型植物病原菌Alternaria Alternate侵染过程中的亲和反应的证据。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。

Toxins and elicitors from plant pathogens appear to function as virulence and avirulence factors, respectively. While, both factors have a common role as an inducer for programmed cell death in plant cells. Here we provide evidence that cell death in a host plant induced by both host-specific AAL-toxin and INF1 elicitor leads to the compatible reaction in the infection process of necrotrophic plant pathogen Alternaria alternate. Both the toxin and the elicitor might act as pathogenicity factors in host-necrotrophic pathogen interactions.
