physiological function | CYP707A1 mutant shows similar phenotype to wild-type in freshly harvested or after-ripen seeds. Seeds of CYP707A1 mutant has its dormancy entirely broken 18 d after ripening. NO enhances the tolerance to abscisic acid in CYP707A1 mutant during germination. Abscisic acid concentrations decrease rapidly during the first 12 h in CYP707A1 mutant. NO enhances the tolerance to abscisic acid in CYP707A1 mutant | Arabidopsis thaliana |
physiological function | CYP707A2 plays a major role in abscisic acid catabolism during the first stage of imbibition. CYP707A2 is involved in NO-induced dormancy break. CYP707A2 mutant shows a strong dormancy in freshly harvested seeds. CYP707A2 mutant still maintains strong dormancy until 30 d. NO does not enhance the tolerance to abscisic acid in CYP707A2 mutant during germination | Arabidopsis thaliana |
physiological function | CYP707A3 mutant shows similar phenotype to wild-type in freshly harvested or after-ripen seeds, with the seeds of CYP707A3 mutant having a slightly higher germination rate than the wild-type. Seeds of CYP707A3 mutant has its dormancy entirely broken 18 d after ripening. NO enhances the tolerance to abscisic acid in CYP707A3 mutant during germination | Arabidopsis thaliana |
