小麦条锈菌（Puccinia striiformis f.）引起的小麦条锈病。小麦黑胫病菌（Pst）对世界小麦生产构成严重威胁。Pst毒力的迅速变化导致现有抗Pst小麦品种的抗性丧失，从而导致病害频繁流行。因此，目前的主要焦点是研究致病性快速变异和小麦抗性协同进化的分子机制。由于缺乏一个稳定的Pst转化体系和小麦转化的困难，利用现有的遗传方法对小麦-Pst互作进行深入研究并不容易。尽管如此，已经做出了相当大的努力来解开小麦-Pst相互作用，并正在取得重大进展。组织学和细胞学揭示了小麦-Pst相互作用过程中感染策略和防御反应的基本细节，鉴定了参与小麦-Pst相互作用的细胞组分，并有助于阐明它们在感染过程或植物防御反应中的作用。转录组和基因组测序揭示了小麦-Pst致病系统的分子特征和动态。广泛的分子分析导致鉴定小麦抗性反应和Pst毒力的主要成分。小麦与Pst相互作用的研究已进入细胞和分子水平研究的新阶段。本文综述了小麦-Pst相互作用的细胞生物学，并将分子分析的新数据与组织细胞学观察相结合。
Wheat stripe rust caused by Puccinia striifor- mis f. sp. tritici (Pst) poses a great threat to wheat production worldwide. The rapid change in virulence of Pst leads to a loss of resistance in currently resistant wheat cultivars, which results in frequent disease epidemics. Therefore, a major focus is currently placed on investigating the molecular mechanisms underlying this rapid variation of pathogenicity and coevolving wheat resistance. Limited by the lack of a system for stable transformation of Pst and the difficulties in wheat transformation, it is not easy to generate deeper insights into the wheat-Pst interaction using established genetic methods. Nevertheless, considerable effort has been made to unravel the wheat-Pst interaction and significant progress is being made. Histology and cytology have revealed basic details of infection strategies and defense responses during wheat-Pst interactions, identified cellular components involved in wheat-Pst interactions, and have helped to elucidate their role in the infection process or in plant defense responses. Transcriptome and genome sequencing has revealed the molecular features and dynamics of the wheat-Pst pathosystem. Extensive molecular analyses have led to the identification of major components in the wheat resistance response and in Pst virulence. Studies of wheat-Pst interactions have now entered a new phase in which cellular and molecular approaches are being used. This review focuses on the cellular biology of wheat-Pst interactions and integrates the emerging data from molecular analyses with the histocytological observations.
