摘要：

Reversions of a mutation lyc 1.5 blocking the first step of the lysine catabolic pathway were isolated. These reversions mapped inside the LYC1 locus. They exhibited an alteration of the regulation of the lysine pool after N and P starvation. This phenomenon did not appear in sexual diploids homozygous for the reversion. Diploids homozygous for the mating type were constructed by protoplast fusion. They displayed a pattern similar to that of the haploids. The expression of this mutation is apparently under the control of the physiological state of the mating type.
