Mieslerová B., Lebeda A., Petrželová I., Korbelová P. (2013): Incidence of lettuce downy mildew (Bremia lactucae) and powdery mildew (Golovinomyces cichoracearum) in natural populations of prickly lettuce (Lactuca serriola). Plant Protect. Sci., 39 (Special Issue): S24–S32. The study was focused on the wild pathosystem Lactuca serriola–lettuce downy mildew (Bremia lactucae) and lettuce powdery ...

first report of powdery mildew of rosa persica caused by leveillula taurica from iran

during the study of powdery mildew related to erysiphaceae family from abardeh region in mashhad (khorasan-e-razavi province), one species of rose (rosa persica michx.ex juss, summer 2006) with symptoms of powdery mildew was collected. the symptoms observed with the naked eye including the dense cottony shape mycelia infected the leaf surfaces as well as some parts of the stem. mycelia were den...

Tragopogon dubius, Considerations on a Possible Biomimetic Transfer

Tragopogon dubious is a small herbaceous plant that uses the wind as dispersal vector for its seeds. The seeds are attached to stalked parachutes which increase the aerodynamic drag force on the seeds. This decreases their rate of descent, and hence increases the total distance traveled. The relatively large natural parachute of Tragopogon dubious is an ideal model in a biomimetic structure owi...

Identification and utilization of a sow thistle powdery mildew as a poorly adapted pathogen to dissect post-invasion non-host resistance mechanisms in Arabidopsis

To better dissect non-host resistance against haustorium-forming powdery mildew pathogens, a sow thistle powdery mildew isolate designated Golovinomyces cichoracearum UMSG1 that has largely overcome penetration resistance but is invariably stopped by post-invasion non-host resistance of Arabidopsis thaliana was identified. The post-invasion non-host resistance is mainly manifested as the format...
