Description:

A brief pulse' of red (R) radiatíon increased actívity and protein content of phosphoenolpyruvate carboxylase (PEPC): diis increase was inhibited by cycloheximide. The efifect of R was far-red pulse (FR) reversible when R was followed inunediately (but not after 24 h) by FR. Thus phytochrome was involved in PEPC regulatíon in etiolated maize leaves. Both a lag phase and a saturation exist in the process of R induction of PEPC synthesis: the highest PEPC acitívity was obtained 24 h after R. Etiolated maize leaves of different age showed different sensitivity to R: the highest sensitivity was found in 5 d-old seedlings. 5 min of R was sufficient for inducing PEPC synthesis, and no additíonal increases were obtained in actívity and protein content of PEPC when the R tíme was prolonged.
