1 A pma1-1 mutant of Saccharomyces cerevisiae with reduced H(+)-ATPase activity and the isogenic wild-type strain accumulated high levels of trehalose in response to a temperature upshift to 40 degrees C and after addition of 10% ethanol, but only modest levels in response to a rapid drop in external pH and after addition of decanoic acid. Trehalose H(+)-exporting P2-type ATPase PMA1 Saccharomyces cerevisiae S288C
2 Another finding was that a pma1-1 mutant exhibited a two- to threefold greater capacity to accumulate trehalose than the isogenic wild-type. Trehalose H(+)-exporting P2-type ATPase PMA1 Saccharomyces cerevisiae S288C
