Light was not essential for the development of ribulose-1,5-diphosphate carboxylase protein or catalytic activity in the photosynthetic cotyledons of germinating castor beans (Ricinus communis). Cotyledons developing in the dark showed higher activity than those in the light. Returning cotyledons developing in the light to darkness resulted in a significant increase in ribulose-1,5-diphosphate ...
The use of energized plasma membrane vesicle preparations from cotyledons and roots of Ricinus communis seedlings is described, and evidence is presented for the existence of plasma membrane H(+)/sucrose and H(+)/amino acid symporters. Using fractions isolated from roots, there is evidence for at least two carriers which can transport neutral amino acids and one which can also transport basic a...
