Malate synthesis by CO2 fixation in wheat (Triticum aestivum L.) and lupin (Lupinus luteus) roots was investigated by labeling with $\text{NaH}^{13}\text{CO}_{3}$ as well as with $\text{NaH}^{14}\text{CO}_{3}$. The distribution of 14C label in the malate was examined, using enzymic degradation metho...
