RESUMO
Differences in the soluble protein fraction between the freshly isolated cyanobiont of lichen Peltigera membranacea, the corresponding free-living strain, and Nostoc punctiforme were analyzed. One protein, which was among the most prominent proteins of the freshly isolated cyanobiont, was expressed at a lower level in the corresponding free-living strain and was not detected at all on the two-dimensional gels of N. punctiforme. This protein was partially sequenced, and the corresponding open reading frame (ORF) in the N. punctiforme genome was identified. This ORF contains a fasciclin domain typical of a class of surface-associated proteins involved in cell adhesion. Similar fasciclin motif-containing genes have previously been shown to be symbiotically induced in other symbiotic systems.
