From: Conservation, duplication, and loss of the Tor signaling pathway in the fungal kingdom
TOR gene duplication events. Several independent segmental gene duplications or whole genome duplication events have occurred throughout the fungal kingdom resulting in multiple Tor homologs. A whole genome duplication occurred in the Saccharomyces budding yeast lineage prior to the speciation of the sensu stricto, sensu lato, and related Saccharomycotina species. An independent gene duplication event occurred in the Schizosaccharomyces lineage, resulting in 2 Tor homologs in four Schizosaccharomyces fission yeast species. Independent gene duplication events also occurred in Batrachochytrium dendrobatidis and the edible mushroom Pleurotus ostreatus. Numbers at nodes are bootstrap percentages representing 500 replicates.
