Abstracts |
We amplified and sequenced partial 18S rDNA of fungi in the roots of 11 African myco-heterotrophic plants out of four angiosperm families (Burmanniaceae, Thismiaceae, Triuridaceae, and Gentianaceae). The sequences were cladistically analyzed with published sequences of arbuscular mycorrhizal fungi. We show that all investigated African myco-heterotrophic plants are associated with arbuscular mycorrhizal fungi within a clade of Glomus (Glomus-group A). We reveal a fine-level mycorrhizal specificity for a particular set of arbuscular mycorrhizal fungi within Glomus-group A by Afrothismia hydra (Thismiaceae). Furthermore, we show that the roots of two myco-heterotrophic plant individuals, besides being colonized by representatives of Glomus-group A, also contain DNA of Acaulospora sp. Consequently, Acaulospora is interpreted as a facultative mycorrhizal associate. |
