| Abstract: | Auxin stimulated the synthesis of RNA (incorporation of uracil-2-14Cinto the RNA fraction) in oat coleoptile cells in 10 min. Mitomycin C inhibited the auxin-induced elongation of segmentsof oat coleoptile and pea internode. Auxin did not affect the process of heat denaturation of isolatedpea stem DNA. Based on these experimental results the mode of action of auxinon the template activity of DNA is discussed. (Received September 10, 1968; ) |
