Abstract Nonnative plant invasions can have devastating effects on native communities; conversely, management efforts nontarget and deleterious impacts desirable plants. In the arid sagebrush steppe rangelands of western United States, nonnative winter annual species affect forage production biodiversity. One method proposed to control these is suppress soil seedbank using preemergent herbicide...
Metal contaminants in soil environments derived from industrial pollution have clearly established the need for research on bioavailability and potential health risks. Much research has been conducted on metal sorption in soils. However, there is still a need to better understand the availability of metal contaminants to plants and microbes. Such information will enhance both human health and d...
To assess the role of auxin flows in plant vascular patterning, the development of vascular systems under conditions of inhibited auxin transport was analyzed. In Arabidopsis, nearly identical responses evoked by three auxin transport inhibitor substances revealed an enormous plasticity of the vascular pattern and suggest an involvement of auxin flows in determining the sites of vascular differ...
Title of Thesis: EVALUATION OF CONSERVATION STRIPS AS A CONSERVATION BIOLOGICAL CONTROL TECHNIQUE ON GOLF COURSES Steven D. Frank, Master of Science, 2003 Thesis directed by: Assistant Professor Paula M. Shrewsbury Department of Entomology Conservation strips combine the conservation biological control tactics of beetle banks and flowering insectary strips. Conservation strips were established ...
A requirement for understanding morphogenesis is being able to quantify expansion at the cellular scale. Here, we present new software (RootflowRT) for measuring the expansion profile of a growing root at high spatial and temporal resolution. The software implements an image processing algorithm using a novel combination of optical flow methods for deformable motion. The algorithm operates on a...
The Brassicaceae is a large plant family (338 genera and 3,700 species) of major scientific and economic importance. The taxonomy of this group has been plagued by convergent evolution in nearly every morphological feature used to define tribes and genera. Phylogenetic analysis of 746 nrDNA internal transcribed spacer (ITS) sequences, representing 24 of the 25 currently recognized tribes, 146 g...
the effect of dry material, glycerol and ratio of water to seed in alyssum homalocarpum films on their thickness, transparency, moisture content, tensile strength, elongation and water vapor permeability was investigated using mixture response surface methods. dry material and glycerol were important factors influencing tensile strength, elongation and water vapor permeability. ratio of water t...
