“…Survival of oilseed rape outside cultivation areas is possible. Demographic studies and surveys have shown the ability of oilseed rape (B. napus) to establish self-perpetuating populations outside agricultural areas, mainly in seminatural and ruderal habitats in different countries (reviewed by Devos et al, 2012;Bauer-Panskus et al, 2013;COGEM, 2013;Hecht et al, 2014;Schulze et al, 2014;Katsuta et al, 2015;Busi and Powles, 2016;Nishizawa et al, 2016). oilseed rape is generally regarded as an opportunistic species, which can take advantage of disturbed sites (e.g.…”

The EFSA Panel on Genetically Modified Organisms (GMO) previously assessed the three single events that are combined to produce the three‐event stack oilseed rape (OSR) MS8 × RF3 × GT73. In this Scientific Opinion, the GMO Panel assessed the three‐event stack OSR and subcombinations that have not been authorised previously (i.e. MS8 × GT73 and RF3 × GT73), independently of their origin, for food and feed uses, import and processing, with the exception of isolated seed protein for food. The combination of OSR events, MS8, RF3 and GT73, in the three‐event stack OSR does not raise issues relating to molecular, agronomic/phenotypic or compositional characteristics requiring further investigations. In line with previous assessments and considering the scope of this application, the GMO Panel did not find indications of safety concern for food and feed with trace levels of glyphosate oxidoreductase (GOX)v247 protein derived from the three‐event stack OSR; whereas, the GMO Panel cannot assess the safety of three‐event stack OSR products rich in protein, such as rapeseed protein isolates in feed. As the risk assessment of the three‐event stack OSR could not be completed for products rich in protein, such as rapeseed protein isolates, the GMO Panel is not in a position to complete the food and feed safety assessment of subcombinations within the scope of this application (i.e. MS8 × GT73 and RF3 × GT73). The two‐event stack OSR MS8 × RF3 is outside the scope of this application. Considering the scope of this application, the mode of action of the introduced traits and the data available for the three‐event and two‐event stack OSR MS8 × RF3, the GMO Panel considered that different combinations of the events, MS8, RF3 and GT73, would not raise environmental concerns.

“…Other studies on gene flow from GM B. napus to non-GM B. rapa have been conducted in the United Kingdom and Japan (Warwick et al 2008;Aono et al 2011;Luijten et al 2015). Moreover, the seeds of GM B. napus with herbicide-resistant traits were found along the roadside and railway lines in Japan and Canada, and these spilled seeds survived and crossed with B. rapa relatives (Yoshimura et al 2006;Nishizawa et al 2016). Furthermore, the escapes of GM B. napus event GT73 were reported around the port area and railway in Switzerland, where no cultivation and importation of GM B. napus were allowed (Hecht et al 2014).…”

Background: Unintentional introgression from genetically modified (GM) oilseed rape (Brassica napus) to a relative is inevitable in the open field. A feasible and practical strategy for restricting the spread of GM offspring is to set a reasonable isolated distance between GM B. napus and the relatives. To define the isolated distance, a pollen donor/ recipient pair is a prerequisite to conducting the field trial of pollen flow. However, because the cultivation of GM B. napus is prohibited in Taiwan, it is difficult to obtain relevant information. Thus, this study explored the morphological and genetic characteristics of five varieties of B. napus (donor), three varieties of B. rapa (recipient), and the 15 corresponding F 1 hybrids, aiming to construct phenotypic data and genetic variation data and to select the most appropriate pollen donor/recipient for future field trials of pollen flow. Results: The genome size of all F 1 hybrids estimated using flow cytometry showed intermediate DNA content between B. napus and B. rapa varieties. Most of the F 1 hybrids had intermediate plant height and blooming period, and the rosette leaves type and colors resembled those of B. napus varieties. The results of sequence-related amplified polymorphism (SRAP) showed an average of 9.52 bands per primer combination and 67.87 polymorphic bands among the F 1 hybrid population. Similarity and cluster analyses revealed higher similarity between F 1 hybrids and B. napus varieties than between F 1 hybrids and B. rapa varieties. Furthermore, we identified a specific 1100-bp band (LOC106302894) in F 1 hybrids and B. napus varieties but not in B. rapa varieties. Conclusions: The rosette leaves and the DNA marker LOC106302894 observed in F 1 hybrids are consistent phenotypic and genetic characteristics that can be used to identify the presence of unintentional hybridization from B. napus to B. rapa in Taiwan. Due to the prohibition of GM crop cultivation, the hybridization system of non-GM Brassica species in this study can be utilized as a mimic scheme to conduct pollen flow trials, thus facilitating the determination of the proper isolated distance.

“…The number of publications related to contamination by GM seeds and plant propagating material identified by the literature search was relatively small reflecting general lack of information on these issues. Most of the publications were related to GM grains imported for food and feed purposes, which may escape in the environment (Aono et al., 2011; Cowan, 2014; Devos et al., 2012; Gamarra et al., 2011; Goto et al., 2017; Han et al., 2015; Hanzer et al., 2012; Hecht et al., 2014; Yamaguchi et al., 2003; Kawata et al., 2009; Kim et al., 2006; Lamb and Booker, 2011; Macias-De Ia Cerda et al., 2012; Milcamps et al., 2009; Nikolic et al., 2010; Nishizawa et al., 2009; Nishizawa et al., 2016; Nishizawa et al., 2010; Park et al., 2010; Santa-Maria et al., 2014; Schoenenberger and D'Andrea, 2012; Schulze et al., 2015; Schulze et al., 2014; Serratos-Hernandez et al., 2007; Turkec et al., 2016a,b; Zdjelar et al., 2014). Majority of the cases of occurrence of GM seeds have been detected outside European Union, e.g., in Japan, Korea, Mexico or Argentina, and those have been linked to sites of seed import and transport routes.…”

Genetically modified organisms (GMO), mainly crop plants, are increasingly grown worldwide leading to large trade volumes of living seeds and other plant material both for cultivation and for food and animal feed. Even though all the traded GMOs have been assessed for their safety with regards to human and animal health and the environment, there still are some concerns regarding the potential uncontrolled release in the environment of authorized or unauthorized GM plants. In this review, we identify the possible entrance routes of GM seeds and other propagating plant material in the EU which could be linked to unauthorized release of GMOs in the environment. In addition, we discuss the situation with GM plant cultivation in some non-EU countries in terms of potential risks for GM seed imports. The available body of information suggests that GM seeds and plant propagating material can enter the EU due to problems with labeling/traceability of GM seed lots, contamination of conventional seed lots and accidental release into the environment of grains imported for food and animal feed. Even though cases of uncontrolled release of authorized GMOs, as well as, release of unauthorized GMOs have been reported, they can be generally attributed to adventitious and technically unavoidable presence with little environmental impact. In conclusion, the probability of GM seeds and plant propagating material illegally entering the cultivation in EU is unlikely. However, specific monitoring programs need to be established and maintained to facilitate the compliance of European farmers with the current GMO legislation.
