Some Properties of Cell Suspension Cultures Containinq Citrus Exocortis Viroid
Abstract: Gynura aurantiaca D. C. i the sensitive indicator plant of citrus exoc-ortis viroid (CEV). Cell suspension cultures from healthy and CEV-infectedGynura aurantiaca D. C. have been established. Some properties of the cellsuspension cultures have been described by means of growth, pH and temperaturecurves respectively. CEV cln replicate in cell suspension cultures. The cons-istent detection of CEV and host nucleic acids, through successive subcultures,suggest that the amplification of CEV inhibit the replicati...
