Expression

EC Number Organism Comment Expression
2.4.1.100 Cichorium intybus treatment with the calcium channel blocker LaCl3 prevents the induction of 1-FFT, the calmodulin antagonist W7 decreases the induction of 1-FFT, genistein and staurosporine reduce the expression of 1-FFT, endothal and cantharidin strongly repress the induction of 1-FFT in a very similar manner down
2.4.1.100 Cichorium intybus increasing the carbon availability by increasing the sucrose concentration from 3 to 6% (w/v) does not result in sustained 1-FFT induction, LY-294002 does not affect the induction of 1-FFT expression additional information
2.4.1.100 Cichorium intybus expression of 1-FFT is strongly induced upon transfer to high-carbon/low-nitrogen medium, limiting nitrogen supply by lowering KNO3 and (NH4)2SO4 concentrations to 5 and 0.2 mM, respectively, under an elevated sucrose concentration (6%), results in a strong increase in transcript level for 1-FFT, 1-FFT expression is transiently and only moderately induced during the first 24 h of cold exposure up
3.2.1.153 Cichorium intybus expression of isozyme 1-FEH I is induced by cold stress (12 h at 4°C) up
3.2.1.153 Cichorium intybus expression of isozyme 1-FEH IIa is induced by cold stress (12 h at 4°C) up
