The infection process of plant pathogenic fungi
Um Pflanzen zu infizieren, differenzieren Pilze besonders gestaltete Infektionsstrukturen aus. Dies sind Modifikationen vonHyphen, mit denen die Pilze die Blattoberfläche erkennen, sich z.B. über der Spaltöffnung festsetzen oder in das Blatteindringen. Im Blatt werden Saugorgane ausgebildet um die Nährstoffe aus den Zellen der Pflanze aufzunehmen. Wiruntersuchen wie die Pilze dies bewerkstelligen und wie die Pflanze den Pilz abwehrt.Plant pathogenic fungi differentiate highly specialized infection structures in order to penetrate the host plant. Theyhelp the fungus to recognize the leaf surface, to penetrate into the leaf and to take up nutrients from host cells. Westudy the differentiation of these fungal structures and characterize the defense reactions a plant produces to wall offthe fungus.

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. Origin (projects) |
