Interaction of Kinetin and Various Inhibitors in the Growth of Soybean Tissue

Abstract

Abstract The growth of kinetin‐requiring soybean callus was inhibited by the purine analogs 2,6‐diaminopnrine, 8‐azaguanine and 8‐azaadenine. The purine analog 6‐mercaptopnrine and the antibiotic puromycin were not effective as inhibitors at the concentrations employed. Reversal of the inhibition was attempted by raising the kinetin concentration. Kinetin did not reverse the inhibition due to 2,6‐dianiinopurine but it did lessen to some extent the inhibition due to 8‐azagnanine. It is suggested the kinetin affects RNA metabolism.
