Abstract
Treatment of pea and tobacco leaf discs with the resistance inducer DL -beta-amino-n-butyric acid (BABA) led to a substantial induction of gl utathione reductase (GR, E.C. 1.6.4.2.) enzyme activity. After exposur e to 1 mM BABA for 96 hrs, the GR activities were 3.2-fold and 2.9-fol d higher in pea and tobacco leaf discs, respectively, than GR activiti es in untreated controls. Elevated GR levels may contribute to the ant ioxidative protection of plants during pathogen attack.
