Abstract
Epiphytic lichen vegetation on birch stems was studied in the border areas between Norway and Russia. The area is heavily influenced by sulphur dioxide pollution emitted from Russian nickel smelters.Hypogymnia physodes and Melanelia olivacea were the two most abundant lichen species on birch stems in the investigated area. However, the coverage of H. physodes and M. olivacea was clearly reduced in parts of the investigated area. The lichen vegetation increased with increasing distance from the pollution source, i.e. from a lichen desert to normal background levels. A different pattern of occurrence of the two lichen species was observed.

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
