Cycling of extracellular DNA in the soil environment
A schematic of DNA cycling coupled with genetic transformation is presented to understand its behavior in soil to elucidating the fate of extracellular DNA in the soil environment. Expand
Harvest losses of canola (Brassica napus) cause large seedbank inputs
Abstract The occurrence of volunteer canola has been increasing in western Canada. The objective of this study was to determine the canola seedbank additions incurred during crop harvest onExpand
Modulation of embryo-forming capacity in culture through the expression of Brassica genes involved in the regulation of the shoot apical meristem
Microarray studies showed that Arabidopsis somatic embryogenesis is encouraged by a global hypomethylation of the DNA during the induction phase and by a switch of the glutathione pool towards an oxidized state during the subsequent development phase. Expand
Crop yield and soil nutrient status on 14 organic farms in the eastern portion of the northern Great Plains
Cropping records from 13 organic farms in the eastern Canadian prairies and one in North Dakota (1991 to 1996) were surveyed to determine crop rotation pattern, yields and soil nutrient status. MajorExpand
Secondary seed dormancy prolongs persistence of volunteer canola in western Canada
Long-term seedbank persistence of canola can be reduced by growing genotypes with low inherent potential for the development of secondary seed dormancy under contrasting tillage systems. Expand
Integrated Weed Management: Knowledge-Based Weed Management Systems
Abstract The fundamental role of integrated weed management (IWM) is to provide a source of scientifically based knowledge from which growers can make informed weed-management decisions. TheExpand
Quantitation of transgenic plant DNA in leachate water: real-time polymerase chain reaction analysis.
The results suggest that rainfall events may distribute plant DNA throughout the soil and into leachate water more widely than previously thought. Expand
Separating the effect of crop from herbicide on soil microbial communities in glyphosate-resistant corn
It is shown that seasonality was a significant determinant of denitrifier and fungal abundance as well as their diversity in this study, suggesting in the short term, some microbial communities are robust to changes in their environment by GR crops. Expand
Genetic diversity of feral alfalfa (Medicago sativa L.) populations occurring in Manitoba, Canada and comparison with alfalfa cultivars: an analysis using SSR markers and phenotypic traits
The results suggest that feral alfalfa populations need to be considered in the risk assessment of al falfa containing novel genetically modified (GM) traits and may be regarded as a source of new germplasm for plant improvement. Expand
The Biology of Canadian Weeds. 137. Brassica napus L. and B. rapa L
A concern in agricultural fields where their combined relative abundance has increased over the past few decades, herbicide-resistance and the stacking of genes in volunteer populations conferring resistance to multiple herbicides have contributed to this. Expand
