The strobilurins, oudemansins and related synthetic mimics constitute a new class of respiration inhibitors which inhibit the electron transfer in the bcx complex. These compounds, both natural and synthetic, contain an (£)-/?-methoxyacrylate (MOA) moiety which is responsible for the antifungal and respiration inhibiting properties2). Strobilurin E was detected and isolated in the course of a s...

Information on the tiller development of hybrid bromegrass (Bromus inermis × Bromus riparius Rehm) is limited. The objective this study was to evaluate effect clipping frequency at vegetative and reproductive stages concentrations sugars ‘AC Knowles’ compared ‘Kirk’ crested wheatgrass (Agropyron cristatum L.). This experiment conducted in greenhouse using tillers vernalized plants dug from fiel...

Elevated CO2 and warming may alter terrestrial ecosystems by promoting invasive plants with strong community and ecosystem impacts. Invasive plant responses to elevated CO2 and warming are difficult to predict, however, because of the many mechanisms involved, including modification of phenology, physiology, and cycling of nitrogen and water. Understanding the relative and interactive importanc...

Managers reduce piñon (Pinus spp.) and juniper (Juniperus spp.) trees that are encroaching on sagebrush (Artemisia spp.) communities to lower fuel loads and increase cover of desirable understory species. All plant species in these communities depend on soil water held at . 1.5 MPa matric potential in the upper 0.3 m of soil for nutrient diffusion to roots and major growth in spring (resource g...

Cheatgrass (Bromus tectorum) is an invasive weed in western North America found primarily growing at elevations less than 2200 m. We asked whether cheatgrass is capable of becoming adapted to a marginal habitat, by investigating a population at a high elevation invasion edge. We used a combination of methods, including reciprocal field transplants, controlled environment studies and molecular a...
