| tuberculina-helicobasidium: host specificity of the tuberculina-stage reveals unexpected diversity within the group. | tuberculina species are mitosporic parasites of rust fungi. it was demonstrated recently that tuberculina represents the asexual life stage of the plant-parasitic genus helicobasidium. here we reveal the host specificities of tuberculina and helicobasidium species on rust fungal hosts by means of infection experiments and molecular analyses. we inoculated species of the rust genera chrysomyxa, coleosporium, cronartium, gymnosporangium, puccinia, tranzschelia and uromyces with conidia and with ba ... | 2004 | 21148955 |
