Stepwise Arms Race Between AvrPik and PikAlleles in the Rice Blast Pathosystem
A stepwise mutation that occurred in both pathogens and their respective hosts has played a seminal role in the co-evolutionary arms race evolution in diverse pathosystems. The process driven by rice blastAvrPik and Pik alleles was investigated through population genetic and evolutionary approaches. The genetic diversity of the non-signal domain of AvrPik was higher than that in its signal peptide domain. Positive selection for particular AvrPik alleles in the northeastern region of China was stronger than in the south. The perfect relationship between the functional lineages and AvrPik allele-specific pathotypes was established by ruling out the nonfunctional lineages derived from additional copies. Only four alleles conditioning stepwise pathotypes were detected in natural populations, which were likely created by only one evolutionary pathway with three recognizable mutation steps. Two non-stepwise pathotypes were determined by two blocks in a network constructed by all 16 possible alleles, indicating that a natural evolution process can be artificially changed by a combination of specific single-nucleotide polymorphisms. Assuming that AvrPik evolution has been largely driven by host selection, the co-evolutionary stepwise relationships betweenAvrPik and Pik was established. The experimental validation of stepwise mutation is required for the development of sustainable management strategies against plant disease.

2、Stepwise Arms Race Between AvrPik and PikAlleles in the Rice Blast Pathosystem
稻瘟病病害系统中AvrPik 和PikAlleles基因之间的阶段性军备竞赛。
3、A stepwise mutation that occurred in both pathogens and their respective hosts has played a seminal role in the co-evolutionary arms race evolution in diverse pathosystems.
在不同的病害系统中，发生在病原体以及它们各自的宿主的阶段性突变在协同进化的军备竞赛中起重要作用。
4、The process driven by rice blastAvrPik and Pik alleles was investigated through population genetic and evolutionary approaches.
通过群体遗传和进化的方法，我们对稻瘟病AvrPik 和PikAlleles的等位基因所驱动的这一过程进行研究。
5、The genetic diversity of the non-signal domain of AvrPik was higher than that in its signal peptide domain.
AvrPik非信号域的遗传差异性比它的信号肽域的更高。
6、Positive selection for particular AvrPik alleles in the northeastern region of China was stronger than in the south.
中国东北地区特定的AvrPik基因的阳性选择比南方的更强烈。
7、The perfect relationship between the functional lineages and AvrPik allele-specific pathotypes was established by ruling out the nonfunctional lineages derived from additional copies.
在功能性血统和AvrPik特异的致病型等位基因之间的完美关系通过排除来源于其它同族物的非功能性血统（区别）而确立。
8、Only four alleles conditioning stepwise pathotypes were detected in natural populations, which were likely created by only one evolutionary pathway with three recognizable mutation steps.
只有4个调节逐步致病型的等位基因在自然群体中被检测到，这些自然群体可能只通过一种有3个我们认识到的突变步骤的进化途径产生。
9、Two non-stepwise pathotypes were determined by two blocks in a network constructed by all 16 possible alleles, indicating that a natural evolution process can be artificially changed by a combination of specific single-nucleotide polymorphisms.
两个非阶段性的致病型通过由所有16种可能的等位基因构成的网络中的2个模序得以确定，这表明自然进化过程能通过结合特异的单核苷酸的多态性而被人工改变。
10、Assuming that AvrPik evolution has been largely driven by host selection, the co-evolutionary stepwise relationships between AvrPik and Pik was established.
假设AvrPik的进化大部分由宿主选择所驱动，那么AvrPik和Pik的协同进化的阶段性关系就可以被确立。
11、The experimental validation of stepwise mutation is required for the development of sustainable management strategies against plant disease.
我们需要进行实验验证阶段性突变来开发可持续发展的管理策略来防备植物疾病。
