An oxidative stress condition was induced in citrus flavedo through the application of a gamma-radiation dose of 2 kGy. The development of necrotic lesions in the flavedo layers was preceded by an increase in tyrosine and phenylalanine, and by the transient induction of phenylalanine ammonia-lyase, and was accompanied by the accumulation of phenols, including coumarins and flavanols. The deposition of lignin occurs as well as the synthesis of the phytoalexins scoparone and 4-(3-methyl-2-butenoxy)isonitrosoacetophenone.
