A biochemical study of tobacco subjected to"Cotyledon test"conditions : effect of magnesium, reactions of plants resistant and susceptible to Peronospora tabacina. III. Chemiluminescence induced in tobaccos contaminated or not by blue mold
In young tobacco plants at the cotyledon stage, induced chemiluminescence (CHL), which is an indicator of the bio-physical condition of the membranes, depends on nutrition, the age of the plant and the degree of contamination by Peronospora tabacina A. If the resistance genes are expressed (Mg2+) the CHL is hardly modified. On the other hand, it greatly decreases in a repressive medium (Knop 1/2). This method provides a new approach to host-parasite interactions.
