For example, variations in medullary fumarprotocetraric acid (FA) and cortical usnic acid (UA) were observed in the lichen Cladonia foliacea , but the mechanism of variation is not well understood. The current study aimed to characterise the quantitative variation of FA and UA and to investigate the association between lichen metabolite content and ecological / biological variables. Fungal and algal trees were constructed using fungal (nrITS, RPB2) and algal (nrITS) loci, respectively. Using a chiral chromatographic method, the contents of (-)-UA were determined in 29 C. foliacea specimens and range from 6.88 to 34.27 mg/g dry wt. The FA contents were lower and varied from 1.44 to 9.87 mg/g dry wt. Although the fungal tree showed two well resolved clades, no significant differences of UA or FA contents were found between the two fungal clades. However, a significantly higher UA/FA ratio as well as a unique habitat were found to be associated with specimens which contained the alga Asterochloris lobophora than those specimens associated other Asterochloris algae. Taking all predictive variables into account (i.e. substrate type, elevation, collection season, photobiont identity), the multivariate data analysis indicated that photobiont identity explained most of the variance of LSM contents in C. foliacea . Thus future LSM biosynthetic studies should take the photobiont into consideration when dealing with intraspecific quantitative variation.}, year = {2024}, eissn = {1878-7665}, pages = {403-419}, orcid-numbers = {Farkas, Edit/0000-0002-5245-1079; Xu, Maonian/0000-0002-4346-8020; Lengyel, Attila/0000-0002-1712-6748} } @CONFERENCE{MTMT:34789855, title = {Acetone extract of Cladonia foliacea (Huds.)

Malaria caused by Plasmodium falciparum is a major public health issue in western Kenya and sub-Saharan Africa, accounting for 90% of malaria deaths. The primary methods of malaria prevention are indoor residual spraying and the use of insecticide-treated nets. These tools face challenges such as mosquito resistance to insecticides as well as their toxic effect to the non-target organism, therefore this study aims to explore the application of lichen secondary metabolites as potential oral biological insecticides by assessing mosquito mortality in varying concentrations. Lichen secondary metabolites were extracted from Cladonia foliacea thalli. Bioassay experiments were conducted on A. gambiae Kisumu strain mosquitoes. Mortality rates were measured after ingesting sugar bait and lichen extracts in different concentrations. Three test replicates and negative control were used, with mortality measured after 4, 24, 48, and 72 hours. Analysis using three-way analysis of variance with twoway interactions was performed using R program to determine the effect of different lichen extract concentrations, time of exposures and mosquito sex on mortality. Our results showed that the ingestion of C. foliacea extract at 50 mg/ml and a post-exposure period of 24 to 48 hours had a maximum effect on the mortality rate of targeted male and female A. gambiae . No statistical difference was found between male and female mosquitoes in mortality. Our study confirms firstly that the extract of C. foliacea is a promising oral toxic agent against adult malaria vector A. gambiae .}, year = {2024}, eissn = {1588-2578}, pages = {233-250}, orcid-numbers = {Farkas, Edit/0000-0002-5245-1079} }
