Inheritance of C 4 Enzymes Associated with Carbon Fixation in Flaveria Species

Abstract

Activities and subunit levels of three C(4) enzymes were determined for F(1) hybrids between C(4) and C(3)-C(4)Flaveria species. For phosphoenolpyruvate carboxylase and pyruvate orthophosphate, dikinase, enzyme amounts in the hybrids were close to the mid-parent means. However, activity and subunit levels of NADP-malic enzyme were approximately one-half the mid-parent mean.
