Hormonal control of tobacco crown gall tumor morphology.

R M Amasino1, C O Miller.   

Abstract

The endogenous levels of auxin and cytokinin in teratoma and unorganized tobacco (Nicotiana tabacum L. var Wisconsin #38) crown gall tumor tissues were determined. Teratoma tissues contain levels of auxin and cytokinin favorable for shoot formation, whereas unorganized tumors contain levels of auxin that suppress shoot formation. This conclusion is based upon the observation that when levels of auxin and cytokinin similar to those found in a teratoma were added to the growth medium of nontumorous tobacco tissue, shoot formation resulted; when levels similar to those found in unorganized tumors were added, the normal tissue grew as unorganized callus.
