Transcription Factor bHLH2 Represses CYSTEINE PROTEASE77 to Negatively Regulate Nodule Senescence.

abstract：:Logarithmic growth rates (either fresh or dry weight basis) of tobacco callus tissues grown on 10(-4) to 10(-1) mum cytokinin are increased if gibberellic acid (10(-3)-2 mum) is incorporated into the medium. At higher (1-10 mum) cytokinin concentrations gibberellic acid has little effect on growth rate but extends the...
