Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

The oilseed rape Ms8xRf3, developed by BASF Agricultural Solutions Seed US LLC, is a fertile hybrid tolerant to glufosinate-ammonium containing herbicides. The hybrid is derived through conventional breeding of the male sterile oilseed rape event Ms8 and the oilseed rape event Rf3, called the fertility restorer. Ms8 and Rf3 were produced by Agrobacterium tumefaciens mediated transformation of cells from a conventional oilseed cultivar. The dominant gene for male sterility in event Ms8 is barnase, and the dominant gene for fertility restoration in event Rf3 is barstar. The bar gene, conferring tolerance to glufosinateammonium, is found in both Ms8 and Rf3. The scientific documentation provided in the renewal application for the genetically modified oilseed rape events Ms8, Rf3 and Ms8 x Rf3 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 events Ms8, Rf3 and Ms8 x Rf3 to imply potential specific health or environmental risks in Norway, compared to EU-countries.

The European spruce bark beetle Ips typographus and the North American spruce beetle Dendroctonus rufipennis cause high mortality of spruces on their native continents. Both species have been inadvertently transported beyond their native ranges. With similar climates and the presence of congeneric spruce hosts in Europe and North America, there is a risk that one or both bark beetle species become established into the non-native continent. There are many challenges that an introduced population of bark beetles would face, but an important prerequisite for establishment is the presence of suitable host trees. We tested the suitability of non-native versus native hosts by exposing cut bolts of Norway spruce (Picea abies), black spruce (Picea mariana) and white spruce (Picea glauca) to beetle attacks in the field in Norway and Canada. We quantified attack density, brood density and reproductive success of I. typographus and D. rufipennis in the three host species. We found that I. typographus attacked white and black spruce at comparable densities to its native host, Norway spruce, and with similar reproductive success in all three host species. In contrast, D. rufipennis strongly preferred to attack white spruce (a native host) but performed better in the novel Norway spruce host than it did in black spruce, a suboptimal native host. Our results suggest that I. typographus will find abundant and highly suitable hosts in North America, while D. rufipennis in Europe may experience reduced reproductive success in Norway spruce.
