“…Soybean is an annual almost completely self-pollinating crop in the field, which has a percentage of cross-pollination usually lower than 1 % (Weber and Hanson, 1961;Caviness, 1966;Ray et al, 2003;Lu, 2005;Yoshimura et al, 2006;Abud et al, 2007). Soybean pollen dispersal is limited because the anthers mature in the bud and directly pollinate the stigma of the same flower (OECD, 2000).…”

Soybean MON 87769 was developed using Agrobacterium tumefaciens transformation and was intended to modify the lipid profile of the extracted oil. Soybean MON 87769 contains a single insert consisting of the Pj.D6D gene encoding the Δ6 desaturase protein from Primula juliae and the Nc.Fad3 gene encoding the Δ15 desaturase protein from Neurospora crassa, both involved in the desaturation of endogenous fatty acids into stearidonic acid. The molecular characterisation of soybean MON 87769 does not raise safety issues. Soybean MON 87769 differs from the conventional counterpart in its fatty acid profile. The safety assessment of the newly expressed desaturases identified no concerns regarding potential toxicity and allergenicity. Nutritional assessment of soybean MON 87769 and derived food products did not identify concerns about human health and nutrition. Consumption of MON 87769 soybean oil replacing other oils in food is not expected to result in adverse effects from increased SDA intake as shown in different exposure scenarios. There are no indications of an increased likelihood of establishment and spread of feral soybean plants. Considering the scope of the application, potential interactions of soybean MON 87769 with the biotic and abiotic environment were not considered a relevant issue. Environmental risks associated with a theoretically possible horizontal gene transfer from soybean MON 87769 to bacteria have not been identified. The post-market environmental monitoring plan and reporting intervals are in line with the intended uses of soybean MON 87769. Since the use of oil derived from the soybean MON 87769 will result in a higher intake of SDA, a post-market monitoring plan is recommended to confirm the exposure assessment using realistic consumption data for the European population. Since the use of oil derived from the soybean MON 87769 will result in a higher intake of SDA, a post-market monitoring plan is recommended to confirm the exposure assessment using realistic consumption data for the European population. A comparative analysis of soybean MON 87769 identified no phenotypic or agronomic differences with respect to its conventional counterpart (soybean A3525) and to non-GM soybean reference varieties. However, it confirmed that the composition of soybean MON 87769 differs from that of the conventional counterpart and non-GM soybean reference varieties. The newly expressed desaturases in soybean MON 87769 seeds resulted in an alteration of the fatty acid profile, leading to the appearance of four new fatty acids (stearidonic acid (SDA), -linolenic acid and two trans-fatty acids) and a reduction in linoleic acid (LA). The safety assessment identified no concerns regarding the potential toxicity and allergenicity of the newly introduced desaturase proteins. There are no indications that the genetic modification might change the overall allergenicity of soybean MON 87769 when compared with that of its conventional counterpart. The EFSA GMO Panel concludes that the estimated changes in fat...

“…Caso ocorra uma planta híbrida na progênie da cultivar CD217, esta deverá apresentar a condição de tolerância ao glifosato, considerando-se a sua herança monogênica de dominância completa (F 2 : 3:1). Como esperado, as maiores taxas de fecundação cruzada ocorreram às menores distâncias entre cultivares (Abud et al, 2003;Ray et al, 2003;Yoshimura et al, 2006;Pereira et al, 2007;Schuster et al, 2007).…”

“…Isto pressupõe que a mesma quantidade de pólen transportado em uma direção no campo, o seria na direção oposta. Entretanto, isto é questionável, pois, sabe-se que a taxa de fecundação cruzada é influenciada por diversos fatores, entre eles: cultivar, local (Pereira et al, 2007), ano (Yoshimura et al, 2006), distância entre plantas e manejo de pragas (Abud et al, 2003).…”

Resumo -O objetivo deste trabalho foi determinar o fluxo gênico recíproco entre duas cultivares de soja, uma tolerante e outra sensível ao glifosato, além de aplicar estimadores para determinar a taxa de fecundação cruzada na população e o número de sementes híbridas na progênie. O experimento compôs-se de quatro blocos com 40 fileiras de soja, com 20 fileiras de cada cultivar (CD217 e CD219RR). No estádio R8, cinco fileiras, distantes 0,5, 1, 2, 4 e 8 m da cultivar adjacente, foram colhidas, trilhadas e analisadas quanto à ocorrência de fluxo gênico. Como características marcadoras, foram utilizadas as cores da flor, hipocótilo e pubescência, e a tolerância ao glifosato. As cultivares contrastam quanto às características analisadas, cada uma condicionada por um gene com dois alelos, em interação de dominância completa. Na progênie da cultivar tolerante, a maior taxa de híbridos encontrada foi 0,27% e, na progênie da cultivar sensível, identificou-se 0,83%; pela hipótese do efeito diluição, as taxas de hibridação natural populacional seriam 0,104 e 0,388%, respectivamente. O fluxo gênico recíproco entre as cultivares CD217 e CD219RR não é o mesmo em ambas as direções. Os estimadores propostos são úteis para determinar a taxa de híbridos em amostras de sementes.Termos para indexação: Glycine max, fecundação cruzada, tolerância ao glifosato, OGM. Reciprocal gene flow between conventional and genetically modified soybean cultivarsAbstract -The objective of this work was to determine the reciprocal gene flow between two soybean cultivars, one tolerant and the other sensitive to glyphosate, as well as to use estimators to determine the outcrossing rate in the population and the number of hybrid seeds in the progeny. The experiment was composed of four blocks of 40 soybean rows, of which 20 rows of each cultivar (CD217 and CD219RR). At the R8 stage, five rows, distant 0.5, 1, 2, 4 and 8 m from the adjacent cultivar, were harvested, threshed and analyzed as for the occurrence of gene flow. As phenotypical markers, the trait color of flowers, hypocotil and pubescence, as well as the tolerance to glyphosate were used. The cultivars contrast for all the analyzed traits, each one conditioned by a single gene with two alleles, in a complete dominance interaction. In the tolerant cultivar progeny, the largest outcross rate was 0.27%, and in the sensitive cultivar progeny, 0.83% was identified; by the dilution effect hypothesis, the outcross rates in natural populations would be 0.104 and 0.388%, respectively. The reciprocal gene flow between CD217 and CD219RR cultivars is not the same in both directions. The proposed estimators are useful for determining the hybrid rates in seed samples.

Single events MON 87708 and MON 89788 were combined to produce the stack two-event soybean MON 87708 × MON 89788. The EFSA GMO Panel previously assessed the two single events and did not identify safety concerns in the context of their scope. No new data on single soybean events leading to a modification of the original conclusions on their safety were identified. Agronomic and phenotypic characteristics, as well as compositional data of soybean MON 87708 × MON 89788, did not give rise to food/feed and environmental safety concerns. The EFSA GMO Panel considers that there is no reason to expect interactions between the single events that could impact on the food and feed safety and the nutritional properties of soybean MON 87708 × MON 89788. There are no indications of an increased likelihood of establishment and spread of feral soybean plants. Considering the scope of application EFSA-GMO-NL-2012-108, potential interactions with the biotic and abiotic environment were not considered to be a relevant issue. The unlikely but theoretically possible transfer of the recombinant genes from soybean MON 87708 × MON 89788 to environmental bacteria does not give rise to any safety concern. The post-market environmental monitoring plan and reporting intervals are in line with the scope. In conclusion, the EFSA GMO Panel considers that the information available for soybean MON 87708 × MON 89788 addresses the scientific comments raised by Member States and that the soybean MON 87708 × MON 89788, as described in this application, is as safe as its non-GM comparator and non-GM soybean reference varieties with respect to potential effects on human and animal health and the environment in the context of its scope. Soybean containing the single events MON 87708 (expressing DMO) and MON 89788 (expressing CP4 EPSPS) were assessed previously and no concerns were identified for human and animal health or environmental safety. No safety issue was identified by updated bioinformatic analyses, nor reported by the applicant concerning the two single soybean events, since the publication of the respective scientific opinions. Consequently, the EFSA GMO Panel considers that its previous conclusions on the safety of the single soybean events remain valid.The two-event stack soybean MON 87708 × MON 89788 was produced by conventional crossing to produce soybean tolerant to dicamba and glyphosate-based herbicides. The EFSA GMO Panel evaluated soybean MON 87708 × MON 89788 with reference to the scope and appropriate principles described in its guidelines for the risk assessment of GM plants and derived food and feed, the environmental risk assessment of GM plants and the post-market environmental monitoring of GM plants. The scientific evaluation of the risk assessment included molecular characterisation of the inserted DNA and analysis of the expression of the corresponding proteins. An evaluation of the comparative analyses of the compositional, agronomic and phenotypic characteristics was undertaken, and the safety of the newly expr...
