| Popis: | Fusarium circinatum (teleomorph = Gib- berella circinata) is responsible for the current epi- demic affecting pine trees in native and urban forests along California's central coast. Only eight vegetative compatibility groups have been recovered from sam- ples collected thronghont the pathogen's range in California, This low level of diversity is snggestive of an asexually propagating population. However, cross- es conducted in the laboratory on carrot agar, as well as on Monterey pine (Pinus radiata) twigs, reveal that California strains of the fungus are capable of un- dergoing sexual reproduction. Outcrossing was con- firmed by demonstrating vegetative incompatibility between the progeny and their parents. These results indicate that sexual reproduction is possible within the California population of the pitch canker path.. |
