There was a linear increase in poly (A+) polymerase activity in the C. arietinum epicotyls during germination. Six-day-old auxin treated seedlings showed about 3-4 fold stimulation in enzyme activity, accompanied with 3- fold rise in the relative abundance of poly (A+) RNA levels. Actinomycin D, cycloheximide, cordycepin and amino acid analogues caused dramatic decline in poly (A+) polymerase as well as poly (A+) RNA levels. It seems that auxin induced a de novo synthesis of this enzyme.
