The chalcone synthase (CHS) gene controls the first step in the flavonoid biosynthesis route, the metabolic pathway in
which anthocyanins, phenolic acids, lignins, simply phenols were produced. The transgenic plants with overexpression
of the heterological CHS gene were generated, leading to the increased synthesis of flavonoids, high antioxidant potential
and improve the properties of products obtained such as flax fiber and oil. At the same time, repressing the endogenous CHS
gene should verify the results of research on its overexpression and provide information on its potential role of CHS in the
redistribution of substrates and diversification of metabolites within the phenylpropanoid pathway, especially in relation to
lignins. In flax, CHS down-regulation resulted in tannin accumulation and reduction in lignin synthesis but plant growth was
not affected. This suggests that lignin content and thus cell wall characteristics might be modulated through chalcone synthase
gene activity. The important role of CHS gene is in regulation of cell wall sensing as well as polymer content and arrangement.
CHS-reduced flax also showed significant changes in morphology and arrangement of the cell wall. The additional result of
this work was indication of relationship between the expression of the CHS gene and the metabolism and stability of fatty acid
in flax. Plant with reduction of CHS produced oil with ideal proportion of ?6/?3 fatty acids. Summing up CHS modification
induces signal transduction cascade that leads to modification of flax metabolism in a wide range and positively diversify its
products.
