Expression of the HXT1 gene, which encodes a low affinity glucose transporter in Saccharomyces cerevisiae, is regulated positively in response to glucose by the general glucose induction pathway, involving the Snf3/Rgt2 membrane glucose sensors, the SCF-Grr1 ubiquitination complex and the Rgt1 transcription factor. In this study we show that, in addition to the glucose signaling pathway, regulation of HXT1 expression also requires the HOG pathway. Deletion of components in the glucose signaling pathway or in the HOG pathway results in impaired HXT1 expression. Genetic analyses showed that, whereas the glucose signaling pathway regulates HXT1 through modulation of the Rgt1 transcription factor, the HOG pathway modulates HXT1 through regulation of the Sko1-Tup1-Ssn6 complex. Coordinated regulation of the two signaling pathways is required for expression of HXT1 by glucose and in response to osmostress.
