    Notizen: Summary Reversions of a mutation lye 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 nitrogen and phosphorus 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. We conclude that the expression of this mutation is under the control of the physiological state of the mating type.

    Genetic control of lysine permeases in Saccharomycopsis lipolytica (1979)

    Notizen: Abstract In order to obtain strains of Saccharomycopsis lipolytica impaired in the active transport of l-lysine, mutants resistant to a mixture of l-canavanine, l-4-5-transdehydrolysine and l-S-amino ethylcysteine, taken either all three or two by two, were isolated. These compounds were shown previously to be competitive inhibitors of l-lysine uptake. The resistance patterns and excretion capacity of the mutants were established. All mutants behaved as monogenic. Recombination tests indicated that four genes at least were involved. All mutants were impaired in both high and low affinity l-lysine transport systems. Several hypotheses on the functions of these genes are put forward and discussed.
