The cat1/2/3 triple mutants displayed severe redox disturbance and growth defects under physiological conditions compared with wild-type and the cat2/3 double mutants.
Title: The Arabidopsis catalase triple mutant reveals important roles of catalases and peroxisome-derived signaling in plant development.
All of the study findings suggest that ABI5 regulates seed germination at least partly by affecting ROS homeostasis.
Title: Arabidopsis ABI5 plays a role in regulating ROS homeostasis by activating CATALASE 1 transcription in seed germination.
maintaining higher CAT and POD activities might be one of the reasons that the disruption of AtWNK8 enhances the tolerance to salt stress.
Title: Disruption of AtWNK8 enhances tolerance of Arabidopsis to salt and osmotic stresses via modulating proline content and activities of catalase and peroxidase.
CAT1 has a role in the resistance to the hemibiotrophic bacterial pathogen Pseudomonas syringae via a constitutively activated salicylic acid (SA) pathway.
Title: Altered growth and improved resistance of Arabidopsis against Pseudomonas syringae by overexpression of the basic amino acid transporter AtCAT1.
CAT1 expression levels during senescence are examined.
