Afficher plus [+] Moins [-]Infections of lichenicolous fungi are studied at the cellular level using different microscopic techniques. Confocal laser scanning microscopy of samples stained with Acridine Orange allows the differentiation of hyphae pertaining to a lichenicolous fungus versus hyphae of the host mycobiont. This is similarly possible by hybridizing rRNA in hyphae of a particular symbiont with a specific, labelled DNA fragment. Transmission electron microscopy was used to study details of the interactions among symbionts including the structure of haustoria or ultrastructural features of parasitized cells. The investigations reveal a diversity of infection mechanisms of lichenicolous fungi.
