Puccinia striiformis f. sp. tritici （PsO causes stripe rust, one of the most important diseases of wheat worldwide, cDNA libraries had been constructed from urediniospores, germinated urediniospores and haustoria. However, little is known about the expression patterns of the genes related to the infection process and sporulation of the pathogen. In this study, a custom oligonucleotide microarray was constructed using sequences of 442 gene transcripts selected from Pst cDNA libraries. The expression patterns of the genes were determined by hybridizing the microarray with cDNA from Pst in vitro and Pst-infected wheat leaves. The time course study identified 55 transcripts that were differentially expressed during the infection process in a compatible interaction. They were identified to have functions related to the following biological processes, including carbohydrate and lipid metabolism, energy, cell signaling, protein synthesis, cell structure and division. In an incompatible interaction, 17 transcripts of the pathogen were differentially expressed in resistant wheat leaves inoculated with an avirulent Pst race, ten of which had similar expression patterns to those in the compatible interaction. Several candidates for pathogenicity and virulence/avirulence related genes were also identified. The results of quantitative real-time PCR validated the expression patterns of some selected genes. The study demonstrates that the custom oligonucleotide microarray technology is useful to determine the expression patterns of the pathogen genes involved in different types of the host--pathogen interactions and stages of development.

干旱作为限制作物产量和品质的主要非生物胁迫之一,对全球社会、经济和生态造成巨大损失。在全球气候变化背景下,提高植物抗旱性的重要性日益突显。硅能够提高植物的抗旱性:外源硅的施用可以影响气孔导度,改变蒸腾速率,改善植物水分状况;通过调节气孔动力学、合成光合色素,促进光化学反应,从而改善光合作用;此外硅可通过渗透调节以平衡植物对矿质元素的吸收,以及调节抗氧化防御系统,减轻植物在干旱胁迫中的氧化损伤。总结了硅对干旱胁迫下植物水分利用、光合作用、矿质元素吸收、抗氧化系统、植物激素代谢等方面的作用及相关生理机制。建议未来从复合逆境胁迫、低硅积累植物等方面进一步揭示硅提高植物抗旱性的作用机制,从而为农林生态系统合理利用硅素来提高生产效率提供科学依据和理论基础。
