d ‐Glyceraldehyde 3‐phosphate: NADP oxidoreductasc (phosphorylating), EC 1.2. 1.13, is formed in excised roots of wheat and pea grown in blue light, but not in red light or darkness. The nonphosphorylating d‐glyceraldehyde 3‐phosphate: NADP oxidoreductase, EC 1.2.1.9, if present at all, constitutes only a minor fraction of the total activity. In wheat roots the time‐course for increase in enzyme activity agrees completely with the time course for increase in chlorophyll content, with a lag phase of 3 days for both. The results for pea roots are similar, but less clear‐cut due to interfering enzymes. The results are discussed with reference to a previously published scheme for chloroplast development.
