| the lichen-forming ascomycete evernia mesomorpha associates with multiple genotypes of trebouxia jamesii. | the epiphyte evernia mesomorpha forms a lichen association with green algae in the genus trebouxia. little is known about the population structure of e. mesomorpha. here, population structure of the algal and fungal symbionts was examined for 290 lichen thalli on 29 jack pine (pinus banksiana) trees in manitoba. through phylogenetic analysis of internal transcribed spacer (its) nuclear ribosomal dna (rdna) sequences, five algal genotypes were detected that were nested within t. jamesii. two fung ... | 2006 | 16411936 |
| production and bioactivity of common lichen metabolites as exemplified by heterodea muelleri (hampe) nyl. | based on results of a former study in 2005, this investigation aimed at quantifying uv- and cold temperature stress-induced changes within the secondary metabolite production of the cultured mycobiont of the lichen heterodea muelleri (hampe) nyl. the chemical profiles of the mycobiont cultures and the lichen thallus were determined by high-performance liquid chromatography (hplc) and thin layer chromatography (tlc) analyses. the voucher specimen of h. muelleri produced diffractaic acid as a majo ... | 2008 | 18080715 |
