Oxidative stress induces distinct physiological responses in the two Trebouxia phycobionts of the lichen Ramalina farinacea.
BACKGROUND AND AIMS Most lichens form associations with Trebouxia phycobionts and some of them simultaneously include genetically different algal lineages. In other symbiotic systems involving algae (e.g. reef corals), the relative abundances of different endosymbiotic algal clades may change over time. This process seems to provide a mechanism allowing the organism to respond to environmental ...
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 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 کاملEffect 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 (...
