- •
O. oeni PSU-1 genome contains three trxA genes, a trxB gene, and a ferredoxin reductase annotated gene.
- •
trxA1 is present in few O. oeni strains, and it has an HGT origin from Lb. plantarum.
- •
The expression of the thioredoxin system genes in O. oeni is mostly strain-dependent.
- •
trxA3 is overexpressed in all strains and plays a crucial role in the ethanol and acidity stress response.
