Carrier-mediated Uptake of Arginine and Urea by Volvox carteri f. nagariensis.
Volvox carteri f. nagariensis takes up arginine via a high affinity, highly specific carrier, whereas carriers for neutral and acidic amino acids cannot be detected (even in nitrogen-starved cultures). Exogenous arginine is accumulated against a steep concentration gradient and is incorporated into protein with high efficiency, but it is not catabolized to any significant extent and will not se...
متن کاملSexual Induction in Volvox Carteri
The study of the dependence of reactions on the concentration of various compounds is often of great value in determining reaction mechanisms . In chemical kinetics, it is often found that, according to van't Hoff's rule, the order of dependence of a reaction on the concentration of some compound involved in that reaction is equal to the number of molecules of the compound involved in each reac...
متن کاملThe sexual inducer of Volvox carteri: purification, chemical characterization and identification of its gene.
The sexual inducer of Volvox carteri f. nagariensis is a glycoprotein and one of the most potent biological effector molecules known. It is synthesized by sperm cells and converts asexually growing males and females to the sexual pathway. Until now, large-scale production of the inducer was made impossible by an inherent biological ;switch' mechanism, the spontaneous self-induction of asexually...
متن کاملPurification and partial characterization of a glycoprotein sexual inducer from Volvox carteri.
A method is described for the isolation and purification of the sexual inducer produced by male colonies of the colonial green alga Volvox carteri. The procedure yields a highly purified preparation of the inducer. The biologically active principal is demonstrated to be a glycoprotein with a molecular weight of 32,000.
متن کاملDifferentiation of reproductive structures and experimental sex change in Volvox (Chlorophyta, Volvocaceae)
This paper represents a brief review on current topics in both asexual and sexual reproduction of Volvox L., a green colonial freshwater alga, which is a valuable model of contemporary developmental biology of plants. In the case of asexual life cycle, the main attention is paid to published data on the mechanisms of differentiation into reproductive and somatic cells of Volvox carteri f. nagar...
