General Information

EC Number General Information Comment Organism
1.2.3.1 physiological function exogenous application of several aldehydes to siliques in AAO4 knockout plants induces severe tissue damage and enhance malondialdehyde levels and senescence symptoms, but not in wild-type siliques. Abiotic stresses such as dark and ultraviolet C irradiation causes an increase in endogenous reactive carbonyl species and higher expression levels of senescence marker genes, leading to premature senescence of knockout siliques. In naturally senescent knockout siliques, higher endogenous reactive carbonyl species levels are associated with enhanced senescence molecular markers, chlorophyll degradation, and earlier seed shattering compared with the wild type Arabidopsis thaliana
