| characterization of mycobionts of photomorph pairs in the peltigerineae (lichenized ascomycetes) based on internal transcribed spacer sequences of the nuclear ribosomal dna. | the "one fungus-two photomorphs" hypothesis suggests that certain lichenized fungi can establish a symbiotic relationship with either a eukaryotic or a prokaryotic photobiont. such pairs of photomorphs are well know from cephalodiate peltigerineae. using an ascomycete-specific primer we amplified the internal transcribed spacer region of the nrdna repeat of the mycobiont from total "lichen dna" extracts of peltigera malacea, photomorphs of p. aphthosa, p. britannica, and p. leucophlebia, nephrom ... | 1997 | 9228791 |
| occurrence of laccases in lichenized ascomycetes of the peltigerineae. | following our previous findings of high extracellular redox activity in lichens, the results of the work presented here identify the enzymes involved as laccases. despite numerous data on laccases in fungi and flowering plants, this is the first report of the occurrence of laccases in lichenized ascomycetes. extracellular laccase activity was measured in 40 species of lichens from different taxonomic groupings and contrasting habitats. out of 20 species tested from suborder peltigerineae, 18 dis ... | 2006 | 16797954 |
