Legacies of consecutive summer droughts on soil-borne plant parasitic protists (Oomycota: Stramenopila and Phytomyxea: Rhizaria) and protistan consumers (Cercozoa: Rhizaria) along an experimental plant diversity gradient. [PDF]

New Phytol
Summary Increasing frequencies of severe summer droughts and plant diversity loss disrupt ecosystem functioning and stability of European grasslands. Understanding how these factors interact with pathogens is crucial. We investigated the effects of plant diversity and repeated summer drought on soil‐borne parasites within a grassland biodiversity ...

Comparative Nutritional Studies of Pythium spp. [PDF]

Journal of General Microbiology, 1962
SUMMARY: Nutritional experiments were carried out dealing with (1) the utilization of sulphur compounds; (2) the action of different mineral salts and their interaction. The results showed that the species of Phyhium used grew well at 28° buffered with Sorensen's salt to give an initial pH of 6.5 and incubated for 13 days for Pythium afertile and 10 ...
