Quantifying Gene Flow from Oilseed Rape to Its Wild Relatives
EXTENDED ABSTRACT Gene flow is defined as the movement of genes between populations and is a naturally occurring phenomenon among sexually compatible individuals. Crops have exchanged genes with their wild and weedy relatives for centuries, however this process has recently caused concern. The rapid advances in genetic engineering have hit an immense wall of opposition and gene flow is now seen...
متن کاملBt-transgenic oilseed rape hybridization with its weedy relative, Brassica rapa.
The movement of transgenes from crops to weeds and the resulting consequences are concerns of modern agriculture. The possible generation of "superweeds" from the escape of fitness-enhancing transgenes into wild populations is a risk that is often discussed, but rarely studied. Oilseed rape, Brassica napus (L.), is a crop with sexually compatible weedy relatives, such as birdseed rape (Brassica...
متن کاملIdentification of Drought Tolerant Oilseed Rape Genotypes using Multivariate Analysis
Extended Abstract Introduction and Objective: Drought stress as one of the most important abiotic stress is the main limiting factor of oilseed rape cultivation in arid and semi-arid climates. Therefore, the identification of drought tolerant genotypes is the essential programs in these regions. One of the appropriate methods to identify drought tolerant genotypes is the use of stress toleranc...
متن کاملMonitoring the escape of transgenic oilseed rape around Japanese ports and roadsides.
An investigation was carried out to monitor the escape and spread of oilseed rape (Brassica napus) transgenic plants and the introgression of transgenes to its closely related feral species in Japan. We screened a total of about 7500 feral B. napus, 300 B. rapa, and 5800 B. juncea seedlings from maternal plants in 143 locations at several ports, roadsides, and riverbanks. The presence of glufos...
متن کاملSources and sinks of ammonia within an oilseed rape canopy
Within-canopy profiles of ammonia (NH3) and measurements of the canopy turbulence characteristics were used to calculate the vertical source/sink density profile of NH3 and sensible heat in a mature oilseed rape (Brassica napus) canopy. For the analysis, the inverse Lagrangian technique (ILT) based on localized near-field theory was used. Turbulence was measured with a standard ultrasonic anemo...
