Abstract

Efforts to improve efficiencies in the forest industries have mainly focused on problems within the borders of the company. Thus, there is an unexploited potential for increased efficiency through integrating and coordinating activities between companies. This poster presents games that mimic the forest industry and demonstrate to...

Abstract

Strains of Ceratobasidium bicorne (anamorph uninucleate Rhizoctonia) causing root dieback in nursery-grown conifer seedlings were fruited in the laboratory and the pairing interactions among sibling, single-basidiospore progeny were investigated.No mating reactions were observed. Instead, a high frequency of somatic incompatibility was observed in progeny pairings, indicated by a killing reaction in hyphal anastomosis and by formation of a demarcation line. The F1 progeny could also be fruited, and the level of somatic incompatibility within the F2 progeny remained high, even if lower than in the F1 progeny.The interaction types in pairings within a family of progeny were in all respects similar to those between field isolates, indicating that the species is homothallic. The uninucleate condition of vegetative cells and the basidial characteristics now observed would indicate homokaryotic fruiting, but the possibility of pseudohomothallism remains.We are presently not able to provide an explanation for the mechanism promoting somatic incompatibility in this species, but it seems likely that the classic heterogenic model of somatic incompatibility recognised in basidiomycetes is not applicable here. Alternative mechanisms are discussed.
