Expression

EC Number Organism Comment Expression
1.11.2.3 Arabidopsis thaliana isoform Clo-3 is highly upregulated following exposure to abiotic stresses, such as salt and drought or treatment with salicylic acid or 2,6-dichloroisonicotinic acid, and to biotic stress such as Leptosphaeria maculans infection up

General Information

EC Number General Information Comment Organism
1.11.2.3 physiological function the membrane-bound isoform of caleosin plays a putative role as a peroxygenase involved in oxylipin metabolism during biotic and abiotic stress responses in Arabidopsis. Clo-3 is involved in the generation of oxidised fatty acids in stress-related signalling pathways involving both ABA and salicylic acid. Clo-3 is part of an oxylipin pathway induced by multiple stresses and may also generate fatty acid derived anti-fungal compounds for plant defence Arabidopsis thaliana
