Regulation of cation-coupled high-affinity phosphate uptake in the yeast Saccharomyces cerevisiae.
Studies of the high-affinity phosphate transporters in the yeast Saccharomyces cerevisiae using mutant strains lacking either the Pho84 or the Pho89 permease revealed that the transporters are differentially regulated. Although both genes are induced by phosphate starvation, activation of the Pho89 transporter precedes that of the Pho84 transporter early in the growth phase in a way which may possibly reflect a fine tuning of the phosphate uptake process relative to the availability of external phosphate.
