Abstract
A study of the deoxyribonuclease and ribonuclease activities and nucleic acid levels in sandal affected by spike mycoplasma was made. A serious disturbance in the nucleic acid metabolism noticed at the young leaf stage in the diseased plant suggested a rapid multiplication of the mycoplasma at that stage. The relative levels of nucleic acids and nuclease activities appear to indicate the migration of the infective organism from the older diseased leaf tissue to regions of fresh vegetative growth.
