| pollinator-mediated interactions between a pathogenic fungus, uromyces pisi (pucciniaceae), and its host plant,euphorbia cyparissias (euphorbiaceae). | the plant euphorbia cyparissias is commonly infected by rust fungi of the species complex uromyces pisi. when infected, e. cyparissias is unable to flower, but instead is induced by the fungus to form pseudoflowers. pseudoflowers are rosettes of yellow leaves upon which the fungus presents its gametes in a sweet-smelling fungal nectar. we hypothesized that the fungi, as they are heterothallic, are dependent on insect visitation to cross-fertilize their mating types. we confirmed that insects are ... | 2000 | 10636829 |
