“…Although GR/HR crop weed management offered significant environmental and other benefits GR challenged them (Duke and Powles, 2008). Herbicide-tolerant crops need to be introduced in CA systems and oil seed rape is an excellent example for HT crop in CA (Senior and Dale, 2002;Graer et al, 2007). Glufosinate-and glyphosate-resistant (GR) crops promoted the adoption on NT agriculture (Duke and Cerdeira, 2005).…”

“…Transgenic herbicideresistant plants are in commercial use with tolerance against Glyphosate (N-(phosphonomethyl) glycine) and Glufosinate, best known under the trade names Roundup ® and Basta ® (among others), respectively. High durability of the transgenic herbicide tolerance approach has been anticipated, since the main herbicide involved, glyphosate, has proven efficient for more than two decades before being incorporated into the GMO strategy (see Cerdeira and Duke 2006;Senior and Bavage 2003;Senior and Dale 2002 for further discussion of herbicide tolerance).…”

What are the prospects for genetically engineered, disease resistant plants?

2008

Insect and herbicide-resistant plants are the most widely grown transgenics in agricultural production. No strategy using genetically engineered plants for disease resistance has had a comparable impact. Why is this? What are the prospects for introducing transgenic disease resistant plants to agriculture? We review the biological background for strategies used to make disease resistant GM crops, illustrate examples of these different strategies and discuss future prospects.

“…Allainguillaume, et al (2006) show that the fitness of F 1 hybrids is low, and when added to data from multiple sampling surveys in the UK there is the likelihood of a decline in "transgene abundance" within the F 1 population (p. 1182). Still, the ability of transgenic oilseed rape to remain viable over time is unknown (Senior andDale, 2002), though D'Hertefeldt, et al (2008) recorded GMHT traits in a small number of volunteers in a field that held a GMHT crop ten years previously. However, this study did not account for any nearby GMHT oilseed rape crops that were grown in the meantime and thus it is unclear if the volunteers in question relate to the original GMHT crop.…”

Potential for longevity of novel genetically modified herbicide-tolerant traits in the Irish landscape

With the renewed interest in GM crop technology in Ireland, some concern has been raised in relation to the potential impact on biodiversity in the Irish agri-environment. This concern can focus on the potential for a transgenic trait to cross to wild relatives. A novel trait will be judged to have persisted in a wild population via the successful production of seeds, such that these seeds are viable and result in the establishment of a self-sustaining population. In the case of a herbicide tolerant (HT) trait, feral and volunteer populations can only remain viable if managed with applications of the herbicide that the trait is designed to resist. This surviving population of HT plants would then need to compete successfully with other wild plants in order to prevail in the landscape and persist over time. There are few agricultural crops that can manage this combination, but as oilseed rape plants are often noted along roadsides and hedgerows in Ireland, it is correct to assume that this crop has the ability to be a successful feral survivor. This paper presents the results of a thought experiment, derived exclusively using the academic literature, on the issue of longevity. This is done by taking four hypothetical case scenarios and examining the potential for a combination of events to take place for oilseed rape (Brassica napus); this is selected here because it has a high potential for 'escaping' via pollen-and/or seed-mediated gene flow. A lack of quantitative data on Irish farmland biodiversity hinders solid conclusions, but when management pressure is eased biodiversity stress is lessened.

Herbicide‐tolerant crops in agriculture: oilseed rape as a case study

Abstract: Oilseed rape has been modi®ed extensively by conventional breeding for the production of varieties useful for human consumption (blended vegetable oil and margarine) and industrial processes (rubber additives and high-temperature lubricants).
