PHOTORESPIRATORY-INDUCED SENESCENCE OF PLANTS UNDER CONDITIONS OF LOW CARBON DIOXIDE*

Jack M Widholm 1,2, William L Ogren 1,2
PMCID: PMC223503  PMID: 16591776

Abstract

A light-induced senescence of soybeans at low carbon dioxide concentration has been characterized and ascribed to photorespiration. It is suggested that this system can be used to screen large numbers of plants for photorespiratory-deficient individuals of photorespiratory species. Optimal conditions for this senescence include a low CO2 concentration, a temperature near 34°, high light intensity, and a high oxygen concentration.
