Abstract
The dependence of phenylalanine ammonialyase (PAL) induction in bean suspension cultures on the concentration of naphthylacetic acid (NAA) and kinetin has been investigated and the timing of the effect of each hormone has been determined. NAA was required at an optimal concentration of 1 mg l(-1) 2 days prior to the increase in PAL activity. Kinetin caused a prapid stimulation of the rate of PAL induction and the total amount of PAL induced in a concentration range of 0.1-0.5 mg l(-1) when it was supplied to the cells immediately prior to the expected rise in PAL activity. The inhibitory effect of 2 mg l(-1) NAA on PAL induction was overcome by an increased concentration of kinetin.
