| phenotypic and dna sequence data comparisons reveal three discrete species in the ceratocystis polonica species complex. | ceratocystis polonica and c. laricicola are two morphologically similar species that occur on conifers and reside in the ceratocystis coerulescens species complex. they, however, represent two ecologically distinct entities. c. polonica causes blue stain on norway spruce (picea abies) and other spruce species (picea spp.) in eurasia and is associated with the bark beetles ips typographus, i. typographus japonicus, i. amitinus and i. duplicatus. in contrast, c. laricicola lives in a symbiotic rel ... | 2005 | 16279408 |
| self-fertility and uni-directional mating-type switching in ceratocystis coerulescens, a filamentous ascomycete. | individual perithecia from selfings of most ceratocystis species produce both self-fertile and self-sterile progeny, apparently due to uni-directional mating-type switching. in c. coerulescens, male-only mutants of otherwise hermaphroditic and self-fertile strains were self-sterile and were used in crossings to demonstrate that this species has two mating-types. only mat-2 strains are capable of selfing, and half of the progeny from a mat-2 selfing are mat-1. male-only, mat-2 mutants are self-st ... | 1997 | 9309170 |
