Resumo: | In Orchidaceae, association with symbiotic fungi is required for seed germination and seedling development, thereby being the main energy source during the first steps of germination. Colombia is one of the countries with the greatest biodiversity of orchids, with an estimated 3,200 species, but few studies on orchid mycorrhiza have been conducted. In our study, we isolated and sequenced the internal transcribed spacer rDNA region of fungi from two co-occurring Colombian epiphytic orchids, I. utricularioides and P. pusilla, both belonging to the subtribe Oncidiinae. All sequences were recognized as belonging to the genus Ceratobasidium, known to be a common orchid mycorrhizal fungus in both tropical and temperate orchids. One sequence was 100% similar to fungi isolated from I. utricularioides in Costa Rica in a previous study. I. utricularioides was confirmed to be a specialist, associating with only one clade of mycorrhizal fungi. However, P. pusilla was shown to be a generalist, associating with three clades. This finding indicates that the variation in mycorrhizal specificity could be an important factor in the co-existence of orchids. The high affinity between the subtribe Oncidiinae and Ceratobasidium was also reinforced. |
