Effect of Ribitol and Plant Hormones on Aposymbiotical Growth of the Lichen-forming Fungi of Ramalina farinacea and Ramalina fastigiata
This study was aimed at evaluating the growth promoting effect of symbiotic algal polyol (ribitol) and plant hormones on the lichen-forming fungi (LFF), Ramalina farinacea (CH050010 and 40403) and Ramalina fastigiata. The addition of ribitol to basal (malt-yeast extract) medium enhanced the relative growth rates of all three LFF. R. farinacea (CH050010), R. farinacea (40403) and R. fastigiata (...
متن کاملLichen secondary metabolites from the cultured lichen mycobionts of Teloschistes chrysophthalmus and Ramalina celastri and their antiviral activities.
Lichens and spore-derived cultured mycobionts of Teloschistes chrysophthalmus and Ramalina celastri were studied chemically, and results indicated that they produced, respectively, parietin and usnic acid as major secondary metabolites, which were purified and identified. Identification of the compounds was performed by high performance liquid chromatography and structural elucidation by nuclea...
متن کاملPhenolic compounds with in vitro activity against respiratory syncytial virus from the Nigerian lichen Ramalina farinacea.
The extract of the Nigerian lichen Ramalina farinacea showed inhibitory activity against the respiratory syncytial virus in a preliminary assay. A follow-up chemical investigation of this lichen led to the isolation of thirteen phenolic compounds (1-13), including one new hydroquinone depside, designated 5-hydroxysekikaic acid (1), and one new orsellinic acid derivative, 2,3-dihydroxy-4-methoxy...
متن کاملEffects of extracts from lichen Ramalina pacifica against clinically infectious bacteria
Bactericidal activity of crude extracts from lichen Ramalina pacifica were screened against 20 clinical pathogenic strains isolated from different infectious sources which belong to Pseudomonas aeruginosa, Klebsiella pneumonia, Salmonella typhi, Salmonella paratyphi, Echerichia coli, and Staphylococcus aureus. The minimal inhibitory concentration of petroleum ether extract and ethanol extract w...
متن کاملLocal genetic structure in a North American epiphytic lichen, Ramalina menziesii (Ramalinaceae).
Epiphytic lichens possess unique life history traits that can have conflicting effects on genetic structure: symbiotic mutualism between a fungus with its algal or cyanobacterial photobiont, association with a host plant, and ability to reproduce sexually and asexually. Our study species, Ramalina menziesii, has small ascospores that can facilitate long-distance gene movement, and it is capable...
