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.

Det ble orientert om de foreløpige resultatene fra et pågående NFR-prosjekt. De store skogsneglene utgjør et vanskelig artskompleks. Iberiaskogsnegl sprer seg videre nordover langs kysten og innover i landet. Lyse og luftige hager får færre iberiaskogsnegler. Dessuten er den et økende problem i landbruket.

Short days (SD) trigger cessation of elongation growth and transition from an actively growing apex to a terminal bud in woody plants of the temperate and boreal zones. The molecular basis behind this is not well understood in gymnosperm forest trees such as Norway spruce. By combining suppression subtractive hybridization (SSH) libraries and monitoring of gene expression using quantitative RT-PCR analysis, we aimed to identify genes involved in photoperiodic control of growth cessation and dormancy induction in Norway spruce. The gene expression patterns described here will be useful for future detailed functionalanalyses.

The Fusarium genus includes devastating plant pathogenic fungi that cause diseases in cereals around the world. They produce several mycotoxins, including the estrogenic compound zearalenone. To better understand the molecular mechanisms determining zearalenone production, we performed differential display RT-PCR under conditions where Fusarium graminearum and F. culmorum produced high amounts of zearalenone. We found 133 expressed sequence tags (ESTs) and 54 of these were considered to be up-regulated during high zearalenone production. Several of the ESTs were confirmed to be up-regulated by real-time qPCR, but none showed any significant down-regulation in the zearalenone negative mutant Delta PKS4-T9, or were similar to typical gene expression patterns of previously described zearalenone-related genes. Some of the up-regulated ESTs were similar to genes involved in secondary metabolite production, lipid metabolism, transcriptional activation, provision of precursors, signal transduction, transport or detoxification. Several of the ESTs were also located adjacent to one another in the genome and therefore might represent genes involved in the same biosynthetic pathway. Members of six such putative pathways could be found. All sequences were compared to the MIPS F. graminearum Genome Database to verify autocalled gene predictions experimentally and to introduce new exons and gene structures.
