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.

Replication of all positive-sense single-stranded RNA viruses occurs in specific structures in close association with cellular membranes. Targeting of the viral replication complex (RC) to the site of replication is mediated by the interaction of viral-encoded proteins and host factors. Electron microscope studies have shown that Poinsettia mosaic virus (PnMV, family Tymoviridae) infection is associated with the presence of vesicular structures in the chloroplasts, which indicates that the replication of PnMV might occur in association with chloroplast-derived membranes. Using computer assisted homology search, we have identified that the coat protein (CP) of PnMV shows similarity to membrane bound proteins and contains a conserved amino acid sequence motif found in members of the Alb3/Oxa1/YidC protein family. This protein family is involved in the insertion of proteins into intracellular membranes. In this study we carried out localization studies combined with confocal laser microscopy to identify the cellular localization of the PnMV CP. Transient expression of red fluorescent protein (RFP)-tagged PnMV CP in Nicotiana benthamiana protoplast was shown to localize in the chloroplast.

Markets for cash-crops in developing countries are typically characterized by a concentration of buyer power at different levels of the supply chain. For instance, small-scale coffee farmers sell their produce to a middleman, who in turn sells the coffee onward to an exporter, often a foreign multinational, with monopsony power in the hands of the purchasers at both levels. We analyze pricing behavior and welfare with different assumptions regarding market power. In particular, we show that a more powerful exporter is likely to benefit the producers and may even lead to higher welfare for the producer country as a whole.
