Mutualistic symbioses are ubiquitous and among one of the most crucial biological interactions. Some of the most iconic examples are fungal-photoautotroph mutualisms such as lichens, mycorrhizal-plant, and endophytic fungal-plant symbioses. Yet little is understood about the earliest origins of such microbial mutualisms, and more precisely, how they relate to the origin of land plants. The study of the evolution of fungal-photoautotroph symbioses is often limited to comparative genomic techniques due to the few genetic tools available for studying extant interactions. Recent work suggests that extant fungal-plant interactions have their origins in fungal-algal associations.In Chapter 1, I review the evolution of …
