Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....
Optimum growth temperatures were determined for nine strains of Streptococcus thermophilus and ten strains of Lactobacillus bulgaricus, all commercial yogurt or yogurt
starter isolates. Optimum growth temperatures ranged from 35 C to 42 C for S.thermophilus strains, averaging 38.6. Optimum growth temperatures for L.bulgaricus strains ranged from 43 C to...
The Clarno Formation is a series of volcanic, volcaniclastic, and related intrusive rocks located in central Oregon. It is the westernmost extent of a broader Eocene magmatic belt that covers much the western United States. The magmatic belt stretches eastward from Oregon to western South Dakota, and from the Canadian...
Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled
signaling pathways. Prior research suggested that some isoforms of PLC-β may exist
and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation
assays of differentially-tagged PLC-β constructs and sizeexclusion
chromatography of native PLC-β support homodimerization...
Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'.
The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...
Two forest management objectives being debated in the context of federally managed landscapes in the US Pacific Northwest involve a perceived trade-off between fire restoration and C sequestration. The former strategy would reduce fuel (and therefore C) that has accumulated through a century of fire suppression and exclusion that has...
The anaerobic and highly reductive conditions found in the ovine rumen are considered favorable for the degradation of the nitroaromatic explosives such as hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). In this study, we used stable-isotope-probing to determine the bacteria responsible for the degradation of RDX in the rumen. Results indicate 10 μg mL⁻¹ (45...
The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...
