Upregulation of expression of GA3ox1 by nitrate in phyB mutant in the dark is diminished when the djc75 mutation is introduced. RT–PCR analysis of XTH5, RD29B, GA3ox1, GA2ox2 and CYP707A2 in phyB and djc75-1/phyB mutants. phyB and djc75-1/phyB mutant seeds were imbibed in the dark for 1 d. TUB was included as a control. Micro, micronutrients.
