Filamentous fungi in the subdivision Pezizomycotina (Ascomycota) display an impressive diversity of mating strategies. These mating systems are all controlled by the mating-type (MAT) genes, some of which are conserved, even among distantly related genera. In order to facilitate effective communication between researchers, a system was established in 2000 to name these genes and this has subsequently been widely applied. However, due to the rapid growth in the number of described MAT genes in the Pezizomycotina, an evaluation of the manner in which the nomenclature system has been applied is warranted and revisions should be considered. We address this challenge by doing a systematic review of the nomenclature associated with the MAT1 locus and its associated genes described in the Pezizomycotina. Several problems in the application of the nomenclature system were identified and addressed. These included proposed revisions of the nomenclature system to provide a more accurate description of the mating-type genes. We anticipate that this review will reduce confusion and that it will be useful in future characterisation of mating-type genes.

Pezizomycotina（Ascomycota）细分中的丝状真菌表现出令人印象深刻的交配策略。这些交配系统全部由交配型（MAT）基因控制，其中一些基因即使在远缘属中也是保守的。为了促进研究人员之间的有效交流，2000年建立了一个命名这些基因的系统，该系统随后得到了广泛应用。然而，由于在Pezizomycotina中所描述的MAT基因的数量迅速增长，因此有必要对命名系统的应用方式进行评估，并应考虑对其进行修订。我们通过系统地审查与MAT1相关的术语来应对这一挑战位点及其在Pezizomycotina中的相关基因。确定并解决了命名系统应用中的几个问题。这些包括对命名系统的拟议修订，以提供对交配型基因的更准确描述。我们预计，这项审查将减少混乱，并且它将在将来对交配型基因的表征中有用。
