Trehalose pathway transcripts are significantly abundant along the pathway from D-glucose to trehalose 6-phosphate in yeast cultures exposed to 7% ethanol for 30 min at log-phase growth. Trehalose has a protective role after ethanol exposure. Although estimates of trehalase expression are consistent with an increase in transcripts responsible for degradation of trehalose (NTH1, shown; ATH1, not shown but very similar), neither gene has nonoverlapping 95% credible intervals in the two conditions.
