| Summary, etc. |
Elicitation of suspension culture cells of spruce [Picea abies (L.)Karst]with a fungal cell wall preparation of the spruce pathogenic fungus Rhizosphaera kalkhoffii Bubak induced inactivation of extracellular enzymes. Extracellular peroxidase,/3-glucosidase and acid phosphatase, secreted by the ceils during growth, and also oramylase and pectinase from Aspergillus strains, added to an elicited cell culture, were inactivated. Inactivation is caused by an elicitor-mediated transient release of H202 from the cells (oxidative burst). H202 released into the medium was determined with ABTS (2,2'-Azino-bis-(3-ethylbenthiazoline-6-sulfonate)) (formation of blue colour)and with phenol red (destruction of pH indicator). The release started only minutes after beginning of elicitation and its inactivating effect existed for more than 1 day. Release of H202 is a biphasic process with a first smaller maximum at 1 h, followed by a second larger increase, peaking at 5-6 h and returning to approximately the control levels thereafter. Also H202 is transiently released in small quantities from cell incubations in the absence of elicitor as a stress response of the cells to manipulations of the cultures. Extracellular enzymes secreted into the medium could also be inactivated by direct addition of exogenous H202. Catalase prevents inactivation of the secreted extracellular enzymes, however, to a limited extent only because, as a result of contact of cells and medium, catalase becomes inactivated. The ionophores A 23187 and cycloheximide induced release of H202 and, when present together with elicitor, induction was synergistically increased. |
