Some of the species included in this thesis are considered pests of economic importance in many areas they have invaded. Despite the importance of the family Ceratocystidaceae very little to nothing is known about the genetics of the mating systems as well as the mating strategies employed by species in Ambrosiella, Bretziella, Chalaropsis, Catunica, Davidsoniella, Meredithiella, Phialophoropsis, Toshionella and Wolfgangiella which constitute half the number of genera within this family. Overall, we were successful in identifying the MAT1-1-1, MAT1-1-2, MAT1-2-1 and MAT1-2-7 in these species. Phylogenetic analysis of the MAT1-1 and MAT1-2 protein sequences from these species and related Sordariomycetes were also performed to corroborate the identification of the predicted MAT genes.en© 2023 University of Pretoria.
