Abstract In Central Europe, drought is the most important limiting factor for autumn‐sown cereals. Due to decline in groundwater, it a priority use less water‐demanding forms of crop production. Water efficiency ( WUE ) can only be increased if cultivars with satisfactory water management traits are grown, so that they exploit reserves soil even occurs during vegetation. consumption and winter wheat genotypes were investigated model experiment carried out climate‐controlled glasshouse. The...

The fungal homotetrameric flavoprotein pyranose 2-oxidase (P2Ox; EC 1.1.3.10) catalyses the oxidation of various sugars at position C2, while, concomitantly, electrons are transferred to oxygen as well alternative electron acceptors (e.g. oxidized ferrocenes). These properties make P2Ox an interesting enzyme for biotechnological applications. Random mutagenesis has previously been used identify variant E542K, which shows increased thermostability. In present study, we selected Leu537...
