Název v původním jazyce

Relationship between secondary structure of elicitins, proteinaceous elicitors of Phytophthora sp. and defense reaction induced in tobacco cells.

Popis výsledku v původním jazyce

Elicitins are secreted specifically by the fungi Oomycete genera Pythium and Phytophthora [1, 2]. Biological function of elicitins is currently unknown. The response is induced by the interaction of elicitins with a putative receptor located on the cytoplasmic membrane. The transfer of signal through the receptor triggers phosphorylation-dephosphorylation cascades in the tobacco resulting in alkalization of the extracellular medium, efflux of potassium and chloride ions, influx of calcium, production ofthe active species from oxygen [3, 4], changes in composition of the cell wall and the induction of acquired systemic resistance. Binding of sterols to the cavity of cryptogein (elicitin from P. cryptogea) seems to be essential for consecutive association of the cryptogein with a receptor and induction of a biological response in a plant [5]. We prepared a series of mutants of cryptogein, one of the most potent elicitors of this group, with altered capacity of binding sterols (L19-R, I6
