Transgene insertions might have unintended side effects on the transgenic host, both crop and hybrids with wild relatives that harbor transgenes. We employed proteomic approaches to assess protein abundance changes in seeds from Bt-transgenic oilseed rape (Brassica napus) and its hybrids with wild mustard (B. juncea). A total of 24, 15 and 34 protein spots matching to 23, 13 and 31 unique genes...

When growing different transgenic herbicide-resistant oilseed rape cultivars side by side, seeds with multiple herbicide resistance can arise, possibly causing problems for the management of volunteer plants. Large-scale field experiments were performed in the years 1999/2000 and 2000/2001 in order to investigate the frequencies and the consequences of the transfer of herbicide resistance genes...

This study developed an approach for remote estimation of Vegetation Fraction (VF) and Flower Fraction (FF) in oilseed rape, which is a crop species with conspicuous flowers during reproduction. Canopy reflectance in green, red, red edge and NIR bands was obtained by a camera system mounted on an unmanned aerial vehicle (UAV) when oilseed rape was in the vegetative growth and flowering stage. T...

The use of efficient rates of nitrogen (N) fertilizer application is important with regard to increasing crop productivity and maintaining environmental sustainability. Rice-oilseed rape rotations are a mainstay of the economy and food security of China. Therefore, a field experiment was carried out during 2011-2013 in Honghu to identify the most appropriate N application rates for enhancing cr...

Calmodulin-binding transcription activators (CAMTAs) play important roles in various plant biological processes including disease resistance and abiotic stress tolerance. Oilseed rape (Brassica napus L.) is one of the most important oil-producing crops worldwide. To date, compositon of CAMTAs in genomes of Brassica species and role of CAMTAs in resistance to the devastating necrotrophic fungal ...

management of nitrogen fertilization in crops is one of the most important components of integrated weed management. a two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and n content of wild mustard on oilseed rape yield. a set of factorial treatments was arranged in a randomized complete block design with four replications. treatments w...

now a day winter cover crops planting has been attended to reduce herbicide application. an experiment was carried out at the research farm of agriculture faculty, bu- ali sina, university, in 2009. the experiment was a randomized complete block design with three replications. the trial included of five treatments consists of no cover crop, rye, winter oilseed rape, barley and triticale. the re...

The objective of this study was to compare an introduced warm-season perennial grass (plains bluestem, Bothriochloa ischaemum) to native tallgrass prairie for cow-calf production. Three systems were used, two based on tallgrass prairie with two different forms of protein supplementation and one based on plains bluestem as the primary forage. The systems were as follows: 1) native tallgrass prai...

blackleg disease of oilseed rape, caused by leptosphaeria maculans, is one of the three most important diseases of the plant in iran. it is also considered as one of the most important diseases of oilseed rape worldwide which causes serious yield losses. during 2010 the oilseed rape fields were surveyed at province golestan and plant samples demonstrating suspected symptoms of the disease were ...
