The differentiation capacity of isolated loach (Misgurnus fossilis L.) blastoderm.
Experiments on the capacity of the isolated teleost blastoderm to undergo development when cultivated in vitro have revealed species differences in the time of initiation of blastoderm differentiation. Thus the Fundulus blastoderm acquires the ability to develop after being separated from the yolk at the stage of 32 blastomeres (Oppenheimer, 1936) while the blastoderms of pike and of salmon dif...
متن کاملBlubber fatty acid profiles indicate dietary resource partitioning between adult and juvenile southern elephant seals
When resources are limited or patchy, a species may develop some degree of resource partitioning to reduce intra-specific competition. Development of intra-specific resource partitioning is more pronounced in species with clear phenotypic variation among individuals (e.g. age or sex). Southern elephant seals Mirounga leonina have pronounced sexual dimorphism and range widely in size and foragin...
متن کاملThe primary structure of oocyte and somatic 5S rRNAs from the loach Misgurnus fossilis.
Somatic and oocyte 5S rRNAs from the liver and unfertilized eggs of the loach (Misgurnus fossilis have been sequenced and found to differ in six nucleotides. All the substitutions are confined to the 5'-half of the molecules; 4 of them are pyrimidine-pyrimidine substitutions, and 2 are purine-pyrimidine ones. Considerable differences, both in the position and the character of substitutions, hav...
متن کاملAlterations in Synthesis and Repair of DNA during the Development of Loach Misgurnus fossilis
Using a modified radiolabeled primer extension method (we named this modification misGvA-"misincorporation of G versus A") we have investigated the DNA synthesis and repair at early and late stages of development of loach Misgurnus fossilis. The misincorporation activity of DNA polymerase iota (Pol ι) in wild-type loach could not be detected by this method at any stage of loach development. In ...
متن کاملRNA synthesis in te early embryogenesis of a fish (Misgurnus fossilis).
Synthesis of ribonucleic acids in early embryos has been extensively studied during recent years in a number of laboratories and has been shown to begin shortly after fertilization (Kafiani, Tatarskaya & Kanopkayte, 1958; Wilt, 1963; Brown & Littna, 1964; Decroly, Cape & Brachet, 1964; Glisin & Glisin, 1964; Kafiani & Timofeeva, 1964, 1965; Nemer & Infant, 1965). Early embryos of Xenopus (Brown...
