Development of Pyrimidine-metabolizing Enzymes in Cotyledons of Germinating Peas.
Mechanisms controlling conversion of orotic acid-6-(14)C to uridine-5'-phosphate in cotyledons of germinating Alaska peas (Pisum sativum L.) were investigated. The content of 5-phosphoribosyl-1-pyrophosphate was very low in dry seeds, increased to a maximum after about 12 hours of imbibition, and then rapidly declined. Orotidine-5'-phosphate pyrophosphorylase and orotidine-5'-phosphate decarbox...
متن کاملSenescence of Cotyledons of Germinating Peas. Influence of Axis Tissue.
Seniescenice at the cellular, organ, and organism levels is a poorly understood but nonetheless well established fact. Regardless of the level at which senescence is studied and regardless of the possible interactions between different organs and cells of different ages and functions, senescence is an expression of events at the cellular and subcellular levels. An ideal material, therefore, for...
متن کاملFat Metabolism in Higher Plants XXXVI: Long Chain Fatty Acid Synthesis in Germinating Peas.
A low lipid, high starch containing tissue, namely cotyledons of germinating pea seedlings was examined for its capacity to synthesize fatty acid. Intact tissue slices readily incorporate acetate-(14)C into fatty acids from C(16) to C(24). Although crude homogenates synthesize primarily 16:0 and 18:0 from malonyl CoA, subsequent fractionation into a 10,000g pellet, a 10(5)g pellet and supernata...
متن کامل[Vitamin K].
In this paper, highly sensitive methods for measuring of vitamin K in serum, feces and milk are described. Vitamin K1 and the menaquinone family from the serum, feces and milk were separated by high performance liquid chromatography. The separated K1 and menaquinone families were detected by a fluorescence spectrophotometer after their reduction with sodium borohydride or platinum catalyst colu...
