Genetically modified maize DP41149 x MON 890349 x MON 874119 x DAS-40278-9 was developed by crossing to combine four single events: DP4114, MON 89034, MON 87411 and DAS-40278-9. DP4114 express the Cry1F protein to confer protection against certain lepidopteran pests, the Cry34Ab1 and Cry35Ab1 proteins to confer protection against certain coleopteran pests and PAT protein to confer tolerance to glufosinate-ammonium-containing herbicides. MON 89034 express the Cry1A.105 and Cry2Ab2 proteins to confer protection against certain lepidopteran pests. MON 87411 express the Cry3Bb1 protein to confer protection against certain coleopteran larvae and the DvSnf7 dsRNA confer protection against western corn rootworm, and the CP4 EPSPS protein for tolerance to glyphosate containing herbicides. DAS-40278-9 express the AAD-1 protein to catalyse the degradation of the general class ofherbicides known as aryloxyphenoxypropionates (AOPP) and to confer tolerance to 2,4- dichlorophenoxyacetic acid (2,4-D) herbicides.

Event MON 87429 is a genetically modified maize developed via Agrobacterium tumefaciens transformation. MON 87429 plants contain the transgenes pat, dmo, ft_t and cp4 epsps. Maize MON 87429 encodes the DMO, PAT and FT_T proteins. In addition, maize MON 87429 encodes the CP4 EPSPS protein and utilises an endogenous maize RNAi regulatory element to suppress its expression in pollen. This results in a lack of viable pollen and thus male sterility when MON 87429 plants are exposed to glyphosate-containing herbicides at growth stages ranging from V8 to V13. This is part of a hybridisation system to be used in inbred lines to facilitate the hybrid seeds production. This is not considered an agronomic trait since the application of glyphosate outside the specific growth stages does not lead to male sterile plants but reduces plant yield compared to plants not expressing the same trait. The scientific documentation provided in the application for genetically modified maize MON 87429 is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in event MON 87429 to imply potential specific health or environmental risks in Norway, compared to EU-countries. The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of event MON87429 was not performed by the VKM GMO Panel
Abstract
Stacked event MON 89034 × 1507 × MIR162 × NK603 × DAS‐40278‐9 (EFSA‐GMO‐NL‐2018‐151) is a genetically modified maize developed via conventional breeding. MON 89034× 1507 × MIR162 × NK603 × DAS‐40278‐9 plants contain the transgenes cry1A.105, cry2Ab2, cry1F, Vip3Aa20, cp4 epsps, pat, aad-1 and the phosphomannose isomerase (PMI) used as a selectable marker in the production of MIR162. MON89034 x 1507 x MIR162 x NK603 x DAS-40278-9 maize provides distinct sources for insect resistance combined with three distinct modes of herbicide tolerance: 2,4-D, glufosinate, and glyphosate. The scientific documentation provided in the application for genetically modified maize is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in event maize to imply potential specific health or environmental risks in Norway, compared to EU-countries. The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of event MON 89034 × 1507 × MIR162 × NK603 × DAS‐40278‐9 was not performed by the VKM GMO Panel.

Event MIR162 is a genetically modified maize developed via Agrobacterium tumefaciens mediated transformation of maize embryos. MIR162 plants contain the transgenes vip3Aa20, a modified version of the native vip3Aa1 from Bacillus thuringiensis, and the pmi gene from Escherichia coli. Vip3Aa20 encodes the insecticidal Vip3Aa20-protein, conferring MIR162 with resistance to several species of lepidopteran (order of butterflies and moths) insect pests. Pmi encodes the enzyme phosphomannose isomerase (PMI) which catalyses the isomerization of mannose-6-phosphate to fructose-6-phosphate. PMI was used as a selectable marker during development of MIR162. The scientific documentation provided in the renewal application (EFSA-GMO-RX-025) for maize MIR162 is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in event MIR162 to imply potential specific health or environmental risks in Norway, compared to EU-countries. The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of maize event MIR162 was not performed by the VKM GMO Panel.

The Norwegian Scientific Committee for food an Environment (VKM) has assessed an application for authorisation of refined oilseed rape oil (Aquaterra®) derived from genetically modified oilseed rape line NS-B50027-4 for exclusive use as an ingredient in fish feed in Norway. NS-B50027-4 is also named DHA-canola. This report uses the term oilseed rape. NS-B50027-4 produces omega-3 long-chain (≥C20) polyunsaturated fatty acids (omega-3 LC-PUFAs) in its seeds, with a high level of docosahexaenoic acid (DHA) and a small amount of eicosapentaenoic acid (EPA) and docosapentaenoic acid (DPA). Aquaterra® also contains a significant level of alpha-Linolenic acid (ALA). Whereas ALA can be derived from plants, the primary producers of EPA and DHA are mainly marine microalgae. EPA and DHA are concentrated in the food chain to fish in the oceans and are often referred to as marine omega-3 fatty acids. NS-B50027-4 was developed as an alternative land-based source ofmarine fatty acids, mainly DHA.

Grey mold caused by the necrotrophic fungal pathogen Botrytis cinerea can affect leaves, flowers, and berries of strawberry, causing severe pre- and postharvest damage. The defense elicitor β-aminobutyric acid (BABA) is reported to induce resistance against B. cinerea and many other pathogens in several crop plants. Surprisingly, BABA soil drench of woodland strawberry (Fragaria vesca) plants two days before B. cinerea inoculation caused increased infection in leaf tissues, suggesting that BABA induce systemic susceptibility in F. vesca. To understand the molecular mechanisms involved in B. cinerea susceptibility in leaves of F. vesca plants soil drenched with BABA, we used RNA sequencing to characterize the transcriptional reprogramming 24 h post-inoculation. The number of differentially expressed genes (DEGs) in infected vs. uninfected leaf tissue in BABA-treated plants was 5205 (2237 upregulated and 2968 downregulated). Upregulated genes were involved in pathogen recognition, defense response signaling, and biosynthesis of secondary metabolites (terpenoid and phenylpropanoid pathways), while downregulated genes were involved in photosynthesis and response to auxin. In control plants not treated with BABA, we found a total of 5300 DEGs (2461 upregulated and 2839 downregulated) after infection. Most of these corresponded to those in infected leaves of BABA-treated plants but a small subset of DEGs, including genes involved in ‘response to biologic stimulus‘, ‘photosynthesis‘ and ‘chlorophyll biosynthesis and metabolism’, differed significantly between treatments and could play a role in the induced susceptibility of BABA-treated plants.
