Here we describe the detection, developmental accumulation and cellular location of the putative plant defensin SPI1 (spruce pathogen induced 1), in the gymnosperm Norway spruce [Picea abies (L.) Karst.], using specific antibodies. Contrary to what has been found in angiosperms, it was not detected in the embryo or other parts of the seed, but accumulated during root development. The protein was detected by immunolocalization along the cell membrane of cells forming the root cortex. Furthermore, a significant accumulation of the SPI1 protein was detected in roots during the first day of infection with the fungal pathogen Heterobasidium annosum, but not in response to the pathogens Pythium dimorphum or Ceratocystis polonica

This paper addresses the impacts of degree of risk aversion, subsidy scheme and choice of utility function on optimal farm plans in Norwegian agriculture. Data from a farm business survey (1991-1997) are combined with subjective judgements to formulate a two-stage utility-efficient programming model. Under existing policy and market conditions, the ex ante expectation was that farmers' risk attitudes are unlikely to have a large effect on choice of enterprise mix. The results tend to confirm this view, and a farmer who is hardly risk averse at all would choose the same farm plan as a very risk averse farmer. Factors such as subsidy schemes, market conditions for the products and available labour on the farm are found to be more important determinants of the optimal plans than farmers' risk attitude or the form of the utility function.
