Net starch synthesis isolated chloroplasts of Codium fragile appears to be regulated in a similar manner to that of vascular plants. Exogenous 10 mol m PGA stimulated net starch synthesis at 200 μmol m s (PPFD) by approx. 69%, whilst 10 mol m P not only inhibited synthesis but also promoted net starch degradation. However, unlike vascular plant chloroplasts, 10 mol m G6P was found to stimulate net starch synthesis by approx. 52% under the same conditions. This apparent difference in response to exogenous G6P is discussed in relation to the operation of the P -G6P translocator in chloroplasts of this species.
