| Five strains of Rhizoctonia, selected for their symbiotic and/or pathogenic characteristics, were investigated with regard to growth and pectic enzyme production in culture. Growth patterns of the strains were similar on glucose and pectic carbon sources, pectin being less efficient than glucose in terms of mycelial dry weight produced. Assays of endopolymethylgalacturonase, endopolygalacturonase and protopectinase in culture filtrates showed that on pectin media all of these enzymes were produced by each of the strains although the relative degree of activity varied. Enzyme production by the orchid endophyte strains used was no less than, and in one case was far greater than, that by the pathogenic strains. The significance oc these results is discussed with regard to host/endophyte relationships. | |
