The A mating type factor of Coprinus cinereus regulates part of a developmental sequence that leads to the conversion of the asexual monokaryon into the fertile dikaryon. The A42 factor is a complex of seven genes, at least four of which are involved in determining the specificity of mating interactions. In this report we show that the A42 genes are constitutively expressed in both monokaryons and dikaryons. This has important implications with respect to intracellular recognition of a compatible mating, which requires an interaction between proteins already present within the cells of the mating partners, and for the subsequent maintenance of dikaryotic growth.
灰盖鬼伞的A交配型因子调控着发育序列的一部分,该序列导致无性单核体转化为可育双核体。A42因子是一个由七个基因组成的复合体,其中至少有四个基因参与决定交配相互作用的特异性。在本报告中,我们表明A42基因在单核体和双核体中均组成性表达。这对于细胞内对相容交配的识别具有重要意义,相容交配需要交配伙伴细胞内已存在的蛋白质之间的相互作用,并且对于随后双核体生长的维持也具有重要意义。
