β¦ Synopsis
Using density gradient techniques we have shown that in addition to a location within the cytoplasm all the enzymes of the pentose phosphate pathway are also present within the plastids of apical cells of pea roots. The data are discussed in relation to the hypothesis that the pentose phosphate pathway provides the NADPH for nitrite assimilation, the enzymes of which pathway have previously been shown to be located within the plastids of apical cells of pea roots.
