THE POSSIBLE PARTICIPATION OF GROWTH STIMULANTS AND NUCLEIC ACIDS IN THE MECHANISM OF THE ACTION OF PHYTOCHROME
Abstract
Of the three hypotheses on the mechanism of the action of phytochrome (by means of growth stimulants, by means of a common link in the metabolism, and by a system of regulation) the one which is apparently closest to the truth is the third one which speaks of the action of light which has been absorbed by phytochrome through a system of regulation which includes active, specific DNA and RNA. In support of this concept it is now possible to cite not only information on the diversity, specificity, and genotypic dependence of the reactions of the plants and their individual organs on light and information concerning change of sensitivity to the action of light during the course of ontogenesis, but also the first data on the 'de novo' synthesis of proteins and enzymes under the action of red light. In studying the possibilities for the transmission of external influences on some elements of the system of regulation and in seeking out these sensitive elements the use of phytochrome as the acceptor of light stimulation should play a significant role.
