title: A free radical ubiquitously associated with senescence in plants: evidence for a quinone.
abstract: The interpretation of EPR and ENDOR measurements on an organic free radical which appears to be a universal concomitant of senescence in plants is discussed. On the basis of EPR spectra obtained at 95 GHz it is speculated that the radical is derived from a quinone.
