QUANTITATIVE STUDY OF NOPALINE SYNTHASE IN PLANT CROWN GALLS I QUANTITATIVE COMPARISION OF NOPALINE SYNTHASE IN CROWN GALL LINES OF DIFFERENT PLANT SPECIES
A quantitative method tor determination ot the activity oft nopaline synthase in the crude enzyme extract of crown gall by measurement of the expense of NADPH was established. The activity of this enzyme in vitro for the crown gall lines of potato, sunflower, tobacco and carrot induced by Agrobacterium tumefaciens carrying nopaline type Ti plasmid can represent its quantity in vivo for no any activitor or inhibitor of this enzyme tor sixteen plant crown gall lines induced by four A.tumefaciens strains was m...
