1. Lipid extracts were obtained from castor-bean endosperm tissue at various times during germination and, after purification, the total lipid content was determined. Quantitative measurements of the triglyceride and phospholipid content together with the fatty acid composition were made. 2. The total lipid content of the endosperm rapidly decreased during(More)
Antisaccades require the suppression of a stimulus-driven response (i.e., response suppression) and the computation of a movement plan mirror-symmetrical to the location of a target (i.e., vector inversion). The goal of the present study was to determine whether response suppression, vector inversion or both contribute to previously reported differences in(More)
Endosperm extracts were prepared at various times during germination from intact castor-bean seeds and from seeds from which the embryos had been removed. The sterilized seeds were incubated either on solid water agar or on agar containing 0.3 mM-gibberellic acid. 2. Isocitrate lyase and 3-hydroxyacyl-CoA dehydrogenase had very low activities in the mature(More)
In the endosperm of Ricinus communis (castor bean) a number of glycosyl transferases were found to be present during germination. They catalyze the incorporation of mannose from guanosine diphosphate mannose and of N-acetylglucosamine from uridine diphosphate N-acetylglucosamine into a glycolipid fraction, which had all of the properties of(More)
