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.
摘要
测定了 C(4)和 C(3)-C(4)中间型 Flaveria 种间 F(1)杂种中三种 C(4)酶的活性和亚基水平。对于磷酸烯醇丙酮酸羧化酶和丙酮酸正磷酸二激酶，杂种中的酶含量接近中亲值。然而，NADP-苹果酸酶的活性和亚基水平约为中亲值的一半。
