Abstract
The changes occurring in the nitrogenous compounds during the growth of groundnut seedlings in the dark and light were compared, particular attention being centred on the levels of γ-methyleneglutamine, the principal amide of these plants, and γ-methyleneglutamic acid. The distribution of amino acids and amides in the main organs of normal young and mature plants was also examined. Suggestions are made concerning the possible pathways of synthesis and the functions of γ-methyleneglutamic acid and γ-methyleneglutamine in groundnut plants.
