Fifteen families from the Province's coastal Douglas-fir breeding program are identified as having differential resistance to Phelliunus weiri. The project's first objective of this is to identify and characterise infection and resistance mechanisms in the coastal Douglas-fir- P. weirii pathosystem. Interactions between P. weirii and other important species in second-growth forests will also be studied. All interactions will be investigated using leading-edge techniques in forest pathology, molecular biology and proteomiecs. Aspects particular to P. weirii such as its virulence and diversity across the coastal landscape will be investigated, primarily by the collection and molecular and genetic characterisation of isolates from several biogeoclimatic subzones and host species. Effective extension of research results is the projects fourth objective.
