Fungal pathogens cause many of the most serious crop diseases. One of the principal reasons for the success of this group is their ability to locate and perceive appropriate host surfaces and then to elaborate specialized infection structures. Here we review the processes implicated in surface attachment, germ tube elongation, and development of appressoria. The involvement of surface-acting proteins such as fungal hydrophobins and integrins in these processes is evaluated, along with a description of studies that have revealed the existence of conserved signaling pathways that regulate appressorium formation. Finally, we anticipate the prospect of genome-level analysis of fungal pathogens and the key research questions that will need to be addressed.
真菌病原体引发了许多最为严重的作物病害。该类病原体成功的主要原因之一在于它们能够定位并感知合适的宿主表面,进而形成专门的感染结构。在此,我们综述了与表面附着、芽管伸长及附着胞形成相关的过程。评估了诸如真菌疏水蛋白和整合素等表面作用蛋白在这些过程中的作用,同时描述了揭示调控附着胞形成的保守信号通路存在的研究。最后,我们展望了真菌病原体基因组水平分析的前景以及有待解决的关键研究问题。
