Abstract

The rate of adaptation of high CO2 (5% v/v CO2 in air)-grown Anabaena to a low level of CO2 (0.05% v/v in air) was determined as a function of O2 concentration. Exposure of cells to low (2.6%) O2 concentration resulted in an extended lag in the adaptation to low CO2 concentration. The rate of adaptation following the lag was not affected by the concentration of O2. The length of the lag period is markedly affected by the O2/CO2 concentration ratio, indicating that the signal for adaptation to low CO2 may be related to the relative rate of ribulose-1,5-bisphosphate carboxylase/oxygenase activities, rather than to CO2 concentration proper. This suggestion is supported by the observed accumulation of phosphoglycolate following transfer of cells from high to low CO2 concentration.
