The invention provides a promoter that can be used in the presence of an
organic acid. The promoter includes DNA with promoter activity of high
osmolarity response 7 gene (HOR7 gene), glycelaldehyde 3 phosphate
dehydrogenase 2 gene (TDH2 gene), heat shock protein 30 gene (HSP30),
hexose transport protein 7 gene (HXT7 gene), thioredoxin peroxidase 1
gene (AHP1 gene), or membrane protein 1 associated gene gene) of yeasts.
