To investigate the transport of primary metabolites in Anabaena cylindrica from vegetative cells into heterocysts, intact filaments were labeled with the heterocysts were separated from the vegetative cells after different time intervals, and the labeling patterns were determined. After a 20-s fixation time, a high percentage of labeling of alanine, glutamate and glutamine, and, to a lesser extent, glucose 6-phosphate was found in heterocysts as compared with whole filaments. The results can be… CONTINUE READING
