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.
