physiological function | a T-DNA insertion in the CYP83B1 gene leads to plants with a phenotype that suggests severe auxin overproduction. Mutant seedlings are characterized by increased hypocotyl length, epinastic cotyledons, exfoliation of the hypocotyl, adventitious root formation from the hypocotyl, enhanced secondary root and root hair formation, and eventually callus formation and increasing disintegration of the seedling. Mutant seedlings contain reduced levels of indole glucosinolates. CYP83B1 overexpression leads to loss of apical dominance typical of auxin deficit | Arabidopsis thaliana |
