Evolutionary studies in lichen associations follow that of the fungal symbiont (mycobiont), which is the symbiont after which the lichen is named and forms the majority of the thallus. However, evolution of the algal partner (photobiont) is important to maintain compatibility between symbionts and to optimize productivity of the lichen association. The internal transcribed spacer (ITS) regions of the nuclear ribosomal DNA (rDNA) were examined for primary DNA sequence patterns and for patterns… CONTINUE READING
