Sexual 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 کاملA Preliminary Genetic Investigation of VOLVOX CARTERI.
A preliminary genetic analysis of a number of genetic variants of Volvox carteri f. nagariensis is presented. Techniques are outlined for mutagenesis of Volvox, isolation of mutants and routine genetic analysis. All of the mutants show simple Mendelian segregation patterns and have been tentatively placed in 14 linkage groups.
متن کاملA posttranslationally regulated protease, VheA, is involved in the liberation of juveniles from parental spheroids in Volvox carteri.
The lineage of volvocine algae includes unicellular Chlamydomonas and multicellular Volvox in addition to their colonial relatives intermediate in size and cell number. In an asexual life cycle, daughter cells of Chlamydomonas hatch from parental cell walls soon after cell division, while Volvox juveniles are released from parental spheroids after the completion of various developmental events ...
متن کاملTwo Different Rickettsial Bacteria Invading Volvox carteri
BACKGROUND Bacteria of the family Rickettsiaceae are principally associated with arthropods. Recently, endosymbionts of the Rickettsiaceae have been found in non-phagotrophic cells of the volvocalean green algae Carteria cerasiformis, Pleodorina japonica, and Volvox carteri. Such endosymbionts were present in only C. cerasiformis strain NIES-425 and V. carteri strain UTEX 2180, of various strai...
متن کاملCarrier-mediated Uptake of Arginine and Urea by Volvox carteri
Volvox carteri f. naganensis 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 ser...
