ABSTRACT

Since the discovery of Berberis and Mahonia species. as aecial hosts of the wheat stripe rust pathogen, Puccinia striiformis Westend. f. sp. tritici Eriks. (Pst), their possible role in generating new races of Pst through sexual reproduction, has become a hot issue in the agricultural scientific community. To date, all the investigations about the role of alternate hosts in the occurrence of the wheat stripe rust disease epidemics reveal that it depends on the pathogen species, environmental conditions, and specific climatic situations. In this review, we summarize the current status of alternate hosts of Pst, and their impact on genetic diversity and disease epidemics. Most importantly, an overview of the recent research progress in understanding the role of alternate hosts of Pst is provided.

摘要

自发现小ber和大红花树种以来。作为小麦条锈病病原体Puccinia striiformis Westend的重要寄主。F。sp。Tritici Eriks。（Pst）在通过性繁殖产生新的Pst种族中可能发挥的作用，已经成为农业科学界的热点问题。迄今为止，所有关于候补寄主在小麦条锈病流行中的作用的调查都表明，这取决于病原体种类，环境条件和特定的气候情况。在这篇评测中，我们总结了Pst备用主机的当前状态。，以及它们对遗传多样性和疾病流行的影响。最重要的是，提供了对了解Pst替代宿主的作用的最新研究进展的概述。
