The ornithine cycle [Eq. (8)-(ll)] was proposed by Krebs and Henseleit (1932) to explain urea formation from ammonium derived from amino acid catabolism in the mammalian liver. Since the promulgation of the ornithine cycle was partly based on the natural occurrence of citrulline in juice of the watermelon Citrullus vulgaris) (Wada, 1930), it is not surprising that citrulline is an intermediate in arginine formation in higher plants.
