Expression

EC Number Organism Comment Expression
2.1.1.276 Arabidopsis thaliana the enzyme expression is not regulated by LFY additional information
2.1.1.276 Arabidopsis thaliana the enzyme is significantly upregulated at the SAM during floral transition up
2.1.1.276 Arabidopsis thaliana the enzyme expression is strongly increased by the application of exogenous gibberellic acid up

General Information

EC Number General Information Comment Organism
2.1.1.276 malfunction loss of enzyme function leads to early flowering, whereas transgenic misexpression of the enzyme in specific regions around the shoot apical meristem delays flowering Arabidopsis thaliana
2.1.1.276 physiological function the enzyme is a repressor of flowering that may act as a buffer of gibberellic acid levels at the shoot apical meristem to help prevent premature flowering Arabidopsis thaliana
