Objectives Investigation of immobilization methods promoting the use of silyletherases from Brassica sp. for the efficient and enantiospecific hydrolysis of silyl-protected hydroxyl functions. Results Different supports for adsorptive and covalent binding of the silyletherase SilE-R as well as exposure of the enzyme on the surface of Bacillus subtilis endospores, so-called SporoBeads, were evaluated. While the highest protein...

Key message Spikelet indeterminacy and supernumerary spikelet phenotypes in barley multiflorus2.b mutant show polygenic inheritance. Genetic analysis of multiflorus2.b revealed major QTLs for spikelet determinacy and supernumerary spikelet phenotypes on 2H and 6H chromosomes. Abstract Understanding the genetic basis of yield forming factors in small grain cereals is of extreme importance, especially in the wake of stagnation o...

Key message Genetic modification of spike architecture is essential for improving wheat yield. Newly identified loci for the ‘Miracle wheat’ phenotype on chromosomes 1AS and 2BS have significant effects on spike traits. Abstract The wheat ( Triticum ssp.) inflorescence, also known as a spike, forms an unbranched inflorescence in which the inflorescence meristem generates axillary spikelet meristems (SMs) destined to become ses...

Summary In ever‐changing natural environments, bacteria are continuously challenged with numerous biotic and abiotic stresses. Accordingly, they have evolved both specific and more general mechanisms to counteract stress‐induced damage and ensure survival. In the soil habitat of B acillus subtilis , peptide antibiotics and bacteriophages are among the primary stressors that affect the integrity of the cytoplasmic membrane. Dyn...

Summary The F irmicutes constitute a phylum of bacteria that can be found in a wide variety of habitats, from soil to the gastrointestinal tract of animals, where they have to thrive in complex communities. Competition in these communities usually involves the production of compounds such as antimicrobial peptides ( AMP s) to eliminate competitor organisms. Animals and plants also produce AMP s to control their associated micr...
