Abstract

Space-filling molecular models of selected phytohormones and DNA, employed as described herein, illustrate possible in vivo stereochemical recognition between nucleic acids and intercalated phytohormones. In this regard, the absolute chirality of certain phytohormones, and that of DNA may be essential for the recognition process. It is speculated further that the specific interactions shown by molecular models have significance in the evolution of plant regulatory mechanisms.
