Environmental Toxicology, EarlyView.ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Journal of Integrative Plant Biology, EarlyView.The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

The Sporangia of Thismia americana
Botanical Gazette, 1918 1. In the microsporangia the sporogenous cells develop from hypodermal masses, 4 in number, in the usual fashion. 2. At maturity the innermost parietal layer appears crushed by the large tapetal cells. 3. There is marked abortion of sporogenous cells in the microsporangia. 4.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, EarlyView.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Differentiation in Species of Allomyces: The Production of Sporangia [PDF]
Australian Journal of Biological Sciences, 1971 Conditions have been defined for the production of sporangia by vegetative plants of Allomyces species. Diploid plants produced zoosporangia and released spores in 3-4 hr at 32°C. Haploid plants produced sexual spores in a similar period. The chief factor controlling differentiation to produce sporangia was the supply of amino acids.
