Peppers, a worldwide crop, are threatened by different pathogens. Powdery mildew, biotroph fungal infection, can cause several damages directly on vegetative parts and indirectly fruits. Despite some sources of resistance have been described, commercial genotypes only with partial developed due to the complex nature such variable genetic expression, which depends stage plants. In this paper 49 ...

Two different media were tested: (i) artificial soil “enarenado” (ii) coconut fiber substrate. Each these irrigated with water three saline concentrations: T1 an electrical conducti...

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...
