Název v původním jazyce

Induced changes in phenolic acids and stilbenes in embryogenic cell cultures of Norway spruce by culture filtrate of Ascocalyx abietina

Popis výsledku v původním jazyce

The aim of this work was to identify whether the Ascocalyx abietina culture filtrate has the ability to induce changes in the contents of phenolic substances that might be indicative for the disease response of Norway spruce (Picea abies). We focused onthe accumulation of soluble and cell wall-bound phenolics, stilbenes as well as extracellular peroxidase activities elicited in the embryogenic cell cultures of Norway spruce by A. abietina culture filtrate. Treatment of spruce cells with fungal culturefiltrate (5 and 20% v/v concentrations) evoked an increase in the total contents of phenolic acids (represented by the sum of free, methanol soluble ester- and glycoside-bound phenolics and methanol insoluble cell-wall bound phenolic esters). The challenge with filtrate was in particular manifested in the increase (compared with the control) in the contents of cell wall-bound phenolic acids (by about 100 and 130% in 5 and 20% filtrate, respectively) and soluble phenolic glycosides (by 37
