Abstract
THE stimulation of RNA synthesis in plant cells by auxins1,2 may be due, in part, to gene derepression, since chromatin isolated from hormone-treated cells is a better template. Mathysse and Phillips3 demonstrated that an acceptor protein for auxin can interact with the chromatin to derepress the genome. In their system the hormone and protein do not affect the rate of RNA synthesis if pure DNA. is used as a template. However, the actual mechanism of auxin on RNA synthesis by isolated RNA polymerase system has yet to be elucidated.
