Modulation of the number of membrane-bound auxin-binding sites during the growth of batch-cultured tobacco cells

We studied the modulation of the number of membrane-bound naphthaleneacetic acid (NAA)-binding sites during the growth cycle of tobacco cells in batch culture. Both cell number and specific NAA-binding increased exponentially, but at different rates and for different periods. This caused a character...

Summary:We studied the modulation of the number of membrane-bound naphthaleneacetic acid (NAA)-binding sites during the growth cycle of tobacco cells in batch culture. Both cell number and specific NAA-binding increased exponentially, but at different rates and for different periods. This caused a characteristic modulation of the number of binding sites per cell during the growth cycle: During the first day of the lag phase this number decreased; in the exponential phase it rose markedly, and in the stationary phase it was constant.
