Cre-mediated autoexcision of selectable marker genes in soybean, cotton, canola and maize transgenic plants.

Efficient selectable marker gene autoexcision in transgenic plants of soybean, cotton, canola, and maize is achieved by effective Cre recombinase expression. Selectable marker genes are often required for efficient generation of transgenic plants in plant transformation but are not desired once the transgenic events are obtained. We have developed Cre/loxP autoexcision systems to remove selectable marker genes in soybean, cotton, canola and maize.

A Novel Approach to ICU Survivor Care: A Population Health Quality Improvement Project.

Objectives: Deliver a novel interdisciplinary care process for ICU survivor care and their primary family caregivers, and assess mortality, readmission rates, and economic impact compared with usual care.

Design: Population health quality improvement comparative study with retrospective data analysis.

Setting: A single tertiary care rural hospital with medical/surgical, neuroscience, trauma, and cardiac ICUs.

Vacuolar glyphosate-sequestration correlates with glyphosate resistance in ryegrass (Lolium spp.) from Australia, South America, and Europe: a 31P NMR investigation.

Lolium spp., ryegrass, variants from Australia, Brazil, Chile, and Italy showing differing levels of glyphosate resistance were examined by (31)P NMR. Extents of glyphosate (i) resistance (LD(50)), (ii) inhibition of 5-enopyruvyl-shikimate-3-phosphate synthase (EPSPS) activity (IC(50)), and (iii) translocation were quantified for glyphosate-resistant (GR) and glyphosate-sensitive (GS) Lolium multiflorum Lam.
