Abstract
Trifluralin (α,α,α-trifluoro-2,6-dinitro- N,N -dipropyl- p -toluidine) at 10 −5 M applied to etiolated corn (Zea mays L. ‘Michigan 500′) seedlings 6 or 12 hr before the isolation of chromatin from the roots markedly reduced ribonucleic acid (RNA) synthesis supported by the chromatin. The addition of Escherichia coli RNA polymerase failed to overcome the inhibition. Trifluralin increased the melting temperature of the chromatin. The presence of trifluralin during the isolation and reaction procedure inhibited RNA synthesis indicating possible trifluralin binding to the chromatin with subsequent reduction of template availability for transcription. Trifluralin did not inhibit chromatin activity in soybean [ Glycine max (L.) Merr. ‘Hark’] seedlings.
