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 کاملUnexpected associated microalgal diversity in the lichen Ramalina farinacea is uncovered by pyrosequencing analyses
The current literature reveals that the intrathalline coexistence of multiple microalgal taxa in lichens is more common than previously thought, and additional complexity is supported by the coexistence of bacteria and basidiomycete yeasts in lichen thalli. This replaces the old paradigm that lichen symbiosis occurs between a fungus and a single photobiont. The lichen Ramalina farinacea has pro...
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 کاملA Note on the Lichen Genus Ramalina (Ramalinaceae, Ascomycota) in the Hengduan Mountains in China
On the basis of extensive field investigation and a series of herbarium specimen identifications, we present and discuss the descriptions and distribution of 22 species of Ramalina found in the Hengduan Mountains of southwestern China. In this revisionary study, representatives of the Ramalina genus, including R. americana, R. confirmata, R. dendriscoides, R. obtusata, R. pacifica, R. pentecost...
