Origin and evolution of the powdery mildews (Ascomycota, Erysiphales)
Molecular phylogeny suggests a close relationship of Asteraceae to the early evolution of Golovinomyces. The family Asteraceae, with a geographic origin in South America, expanded into the Northern Hemisphere, where it may have been infected by an ancestor of Golovinomyces, thus starting a close hosteparasite relationship. Using this event as a calibration point, we designed molecular clocks fo...
متن کاملManaging Cucurbit Mildews: New Challenges and New Opportunities
There are two mildew diseases affecting cucurbit crops: powdery mildew and downy mildew. Both fungal pathogens produce wind-dispersed spores that can be moved long distances, thus they cannot be avoided. Fungicides and resistant varieties have been important for managing these diseases. Unfortunately, both pathogens have demonstrated ability to evolve new strains that are not controlled as effe...

متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Inhibition Effects of Silver Nanoparticles against Powdery Mildews on Cucumber and Pumpkin
Powdery mildew is one of the most devastating diseases in cucurbits. Crop yield can decline as the disease severity increases. In this study, we evaluated the effect of silver nanoparticles against powdery mildew under different cultivation conditions in vitro and in vivo . Silver nanoparticles (WA-CV-WA13B) at various concentrations were applied before and after disease outbreak in plants to d...
