General Information

General Information Comment Organism
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
