Hop downy mildew (Pseudoperonospora humuli) and hop powdery mildew (Sphaerotheca humuli) are the most important fungal plant diseases of hop (Humulus lupulus). The early detection and diagnosis of pathogens are often aggravated with symptomless before mass infection or commutation with another pathogens. Molecular analysis of internal transcribed spacer (ITS) regions of rDNA is a novel and very...

Podosphaera is a genus of the powdery mildew fungi belonging to the tribe Cystotheceae of the Erysiphaceae. Among the host plants of Podosphaera, 86 % of hosts of the section Podosphaera and 57 % hosts of the subsection Sphaerotheca belong to the Rosaceae. In order to reconstruct the phylogeny of Podosphaera and to determine evolutionary relationships between Podosphaera and its host plants, we...

Mid-twentieth century malaria eradication campaigns largely eliminated malaria from Paraguay and Sri Lanka. Using these interventions as quasi-experiments, I estimate malaria's effect on lifetime female educational attainment through the combination of pre-existing geographic variation in malarial intensity and cohort exposure based on the timing of the national anti-malaria campaigns. The esti...
