  • Carbohydrate metabolism in lactic streptococci with special reference to galactose

    Creator:
    Lee, Donald Royce
    Abstract:
    Phosphorylation of free galactose by lactic streptococci was mediated by an adenosine triphosphate (ATP) dependent kinase which was repressed by glucose. The phosphoenolypyruvate (PEP) phosphotransferase system (PTS) was not involved in transport of galactose, The conversion of free galactose to glucose was also demonstrated. A key Leloir pathway enzyme, uridine...

  • Developmental mutants of Phaseolus vulgaris L.

    Creator:
    Shii, Chou Tou
    Abstract:
    Hybrids with abnormal development were obtained when particular genotypes of Phaseolus vulgaris L. were crossed. The phenotypic aberrations of the F₁s included retarded growth, chlorosis of the trifoliate leaves and the formation of adventitious roots on the hypocotyls. The expression of the abnormalities was dependent on the temperature. At high...
