Chloroplastic lipocalin

Gene

CHL

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Lipocalin that prevents thylakoidal membrane lipids peroxidation and confers protection against oxidative stress, especially mediated by singlet oxygen in response to high light and other stress (e.g. heat shocks) (PubMed:19674405, PubMed:23837879). Required for seed longevity by insuring polyunsaturated lipids integrity (PubMed:23837879).2 Publications

Pathology & Biotechi

Disruption phenotypei

Increased sensitivity to photo-oxidative stress induced by drought, high light or paraquat, associated with a rapid accumulation of hydroxy fatty acids mediated by singlet oxygen (PubMed:19674405). When associated with disruption in TIL, highly sensitive to temperature, drought and light stresses than the single mutants, exhibiting intense lipid peroxidation. Seeds of this double mutant are very sensitive to natural and artificial aging, associated with the oxidation of polyunsaturated lipids (PubMed:23837879).2 Publications
