In Lens root tips, a direct proportionality between RNA and auxin levels and inverse proportionality between RNA content and RNase activity were found. IAA treatment of the Lens seedlings causes, in the root, both an increase of RNA and auxin content and a decrease of RNase activity. Addition of IAA to the excised roots produces an inhibition of both the decrease of the RNA levels and an inhibition of the increase of the RNase activity. The action of IAA on growth, related to the control of the RNA metabolism is discussed.
