At the present stage of science development it is necessary to develop and implement grape breeding programs for immunity basing on international level knowledge about genetics pathogens that cause culture diseases. The extensive material genes resistance Plasmopara viticola Erysiphe necator ( Uncinula ), which mildew oidium diseases, has been collected thanks MAS technology. There an evidence ...

Methyl salicylate (MeSA) is a plant metabolite that induces defence resistance and an odorous volatile compound presenting green nuances. This was shown to be present in wine samples, sometimes at concentrations above its olfactory detection threshold. MeSA localized grapes, particularly the skins stems, extracted during red vinification. It detected highest wines of several grape varieties, ma...

Streptomyces halstedii JM8 Cel2 is an endoglucanase of 28 kDa that is first produced as a protein of 42 kDa (p42) and is later processed at its C-terminus. Cel2 displays optimal activity towards CM-cellulose at pH6 and 50 degrees C and shows no activity against crystalline cellulose or xylan. The N-terminus of p42 shares similarity with cellulases included in family 12 of the beta-glycanases an...
