Resumen
Heterobasidion annosum is one of the major pathogens to conifers in the
Northern Hemisphere. Research has been carried out to characterise the
molecular mechanism of the pathogenicity in this basidiomycete. One factor
that has limited the research about H. annosum pathogenesis is the lack of

Heterobasidion annosum is one of the major pathogens to conifers in the
Northern Hemisphere. Research has been carried out to characterise the
molecular mechanism of the pathogenicity in this basidiomycete. One factor
that has limited the research about H. annosum pathogenesis is the lack of
coding sequence information. Therefore, a project on producing sequence
data from H. annosum by generating ESTs has been carried out. The collection
of sequence data will assist future research on H. annosum together with
the high density cDNA arrays that were also constructed in this work. It is
interesting that 30% of the genes identified did not have any similarity to any
known proteins and 16% had similarity only with proteins with unknown
functions. Recently, progress has been made in work on mapping the pathogenicity
factors in Heterobasidion using a hybrid between North American P
and S homokaryons. Based on AFLP markers, a genetic linkage map was established
that allowed for mapping QTLs for pathogenic growth towards
seedling roots and pine innerbark. The next step underway is to verify the
identity of candidate genes located within the established region of the
genome. Future functional analysis of both QTL and EST-derived candidate
genes should be aided by the recently established Agrobacterium-mediated
transformation system in Heterobasidion. [--]
