Distribution of Carbon-14 in Polysaccharide after Photosynthesis in Carbon Dioxide labelled with Carbon-14 by Anacystis nidulans

Nature volume 200, pages 260–261 (1963)Cite this article

Abstract

THE reductive pentose phosphate cycle1 has been proposed as the means of formation of hexose during photosynthesis. The enzyme fructose-1,6-diphosphate aldolase is an integral part of the cycle. It was therefore unexpected that Richter2 could not detect aldolase in extracts of the photoautotrophic blue-green alga, Anacystis nidulans. This observation was confirmed and extended by Fewson, Al-Hafidh and Gibbs3 to include other members of the Cyanophyceae. Recently, Kandler4 reported that the distribution of carbon-14 in the products formed during photosynthesis in 14CO2 by A. nidulans was similar to those obtained with Chlorella, an alga which contains aldolase. It therefore became of interest to examine the distribution pattern of carbon-14 in the polysaccharide formed during photosynthesis in 14CO2 by the two types of algae.
