Characterisation of nitrogen stress response genes of the marine Alga Gracilaria Gracilis

Bibliography: leaves 86-97.Low environmental nutrient concentration is the main factor limiting natural production and success of Gracilaria gracilis cultivation in Saldanha Bay, South Africa and nitrogen is the single element of all the nutrients required by seaweeds that is most frequently limiting to growth. Biomass, relative growth rate, the concentration of nitrogen in the growth medium, the mean nitrogen uptake rate of the plant and the amount of nitrogen in the thallus were determined for nitrogen enriched and nitrogen deprived G. gracilis cultures grown in the laboratory
