A Mutant of Arabidopsis thaliana Which Lacks Activation of RuBP Carboxylase In Vivo.

abstract：:Under controlled environment and/or field conditions, vegetative growth (height, internode length, leaf area, shoot dry weight, grain yield) was greater in an F(1) maize hybrid than in either parental inbred. Endogenous gibberellin (GA)-like substances in apical meristem cylinders were also higher in the hybrid than i...
