[Genetic architecture of grain protein content in wheat].

Studies on identification and localization of quantitative traits for grain protein content (QGpc-loci) on chromosomes in Triticum aestivum and Triticum durum are reviewed. Association of QGpc with various traits of morphology, physiology, adaptation and tolerance to abiotic and biotic stressors is shown. Genetic and environmental QGpc contexts that should be taken into account when using molecular markers in breeding for the grain protein content are considered.

[Increase in the yield of recombinant proteins in Saccharomyces cerevisiae yeasts as a result of optimizing their culture conditions].

The optimal one-stage scheme of the cultivation of the recombinant yeast strains was developed. In these strains, the expression of the foreign gene is induced at the medium depletion by phosphorus. The scheme was tested for the producers of human interleukin-2 and bovine gamma-interferon.
