Target-site and non-target-site herbicide tolerance are caused by the prevention of herbicide binding to the target enzyme and the reduction to a nonlethal dose of herbicide reaching the target enzyme, respectively. There is little information on the molecular mechanisms involved in non-target-site herbicide tolerance, although it poses the greater threat in the evolution of herbicide-resistant...
The interaction between environment and genetic traits under selection is the basis of evolution. In this study, we have investigated the genetic basis of herbicide resistance in a highly characterized initially herbicide-susceptible Lolium rigidum population recurrently selected with low (below recommended label) doses of the herbicide diclofop-methyl. We report the variability in herbicide re...
Garlic mustard, an invasive exotic biennial herb, has been identified in the Upper Peninsula of Michigan, but is not yet widely distributed. We tested the effectiveness and impact of management tools for garlic mustard in northern hardwood forests. Six treatment types (no treatment control, hand-pull, herbicide, hand-pull/herbicide, scorch, and hand-pull/scorch) were applied within a northern h...
Herbicide resistant crops are commercially advantageous for efficient field productivity by enabling use of nonselective herbicides for weed management. Herbicide resistant trees could be used to improve productivity and reduce the costs of forest management through to the first and second years post tree establishment. We describe the introduction of the phosphinothricin acetyltransferase (bar...
Methods for woody plant herbicide screening were assayed with the goal of reducing resources and time required to conduct preliminary screenings for new products. Rapid screening methods tested included greenhouse seedling screening, germinal screening, and seed screening. Triclopyr and eight experimental herbicides from Dow AgroSciences (DAS 313, 402, 534, 548, 602, 729, 779, and 896) were tes...
We will extend the topological Gromov-Hausdorff stability [ 2 ] from homeomorphisms to finitely generated actions. prove that if an action is expansive and has shadowing property, then it topologically GH-stable. From this we derive examples of GH-stable actions discrete Heisenberg group on tori. Finally, GH-stability invariant under isometric conjugacy.
Background: b-Thalassemia major is a serious medical problem.Growth retardation is commonly seen in poly-transfused b-thalassemia patients. The exact mechanism of short stature in childrenwith thalassemia major is not well understood, however, it isbelieved to be multi-factorial.Objective: To study the growth state and its relationship to growthhormone (GH) deficiency in b-thalassemia patients....
