Abstrakt: The cultivation of soybean plants is one of the most important crop production sectors in the world. Isoflavones are an important defence against pathogens in soybeans. The aim of the present study was to analyse isoflavone biosynthesis in wild and cultivated soybeans grown in the field conditions in an unfavourable climate. We analysed by LCMS-IT-TOF the composition and content of isoflavonoids, productivity and fungal disease resistance of wild and cultivated. The Hefeng25 and Sfera varieties have the highest isoflavonoid content and fungal tolerance. We have shown a 3-fold increase of total isoflavonoids in Sfera, comparing with wild type, and 4- and 7-fold increases of total isoflavone aglycones in Hefeng25 and Sfera, respectively. Accordingly, the expression of genes encoding enzymes of the isoflavonoid biosynthetic pathway was also maximal in these cultivars. Thus, biosynthetic status is an important indicator of soybean productivity and resistance to pathogens in adverse climates.
