Infection structures of phytopathogenic fungi are modified hyphae specialized for the invasion of plant tissues. Initial events are adhesion to the cuticle and directed growth of the germ tube on the plant surface. At the site of penetration, appressoria are often formed that may have melanized walls and develop high turgor pressure to support the penetration process. The penetration hypha accumulates components of the cytoskeleton in the tip and secretes a variety of cell wall-degrading enzymes in a highly regulated fashion in order to penetrate the cuticle and the plant cell wall. This article reviews recent papers on the cytology, physiology, and molecular biology of the penetration process.

植物病原性真菌的形态发生和渗透机制。

植物病原性真菌的感染结构是专门为入侵植物组织而修饰的菌丝。最初的事件是对表皮的粘附和胚芽管在植物表面的定向生长。在穿透部位，经常形成附生器官，其壁可能是黑色的，并产生较高的膨胀压力以支持穿透过程。穿透菌丝在尖端积累细胞骨架的成分，并以高度调节的方式分泌多种细胞壁降解酶，以穿透表皮和植物细胞壁。本文回顾了有关渗透过程的细胞学，生理学和分子生物学的最新论文。
