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 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 کاملMorphometric and Histological Changes in Cyprinid Loach, Misgurnus anguillicaudatus, in the Early Growth Period
In this study, we measured the morphometric and histological changes in the cyprinid loach, Misgurnus anguillicaudatus, during the early period of growth. Eyes, yolk length, yolk height, and yolk volume of the larva decreased for 16 days post hatching (DPH) (P<0.05). During 60 DPH (P>0.05), the most anterior extension of the head × the posterior end of the supraoccipital, the most anterior exte...
متن کاملA sperm cryopreservation protocol for the loach Misgurnus anguillicaudatus and its applicability for other related species.
The aim of the present study was to establish a protocol of sperm cryopreservation in Misgurnus anguillicaudatus and verify the applicability of the obtained protocol in other loach species. We evaluated the following parameters: inseminating dose, thawing temperatures (20, 25 and 30 degrees C for 10s), extenders (loach or cyprinid extenders), internal cryoprotectants (dimethyl sulfoxide (DMSO)...
متن کاملFirst record of the natural occurrence of hexaploid loach Misgurnus anguillicaudatus in Hubei Province, China.
Natural occurrence of hexaploid loach Misgurnus anguillicaudatus detected in central China is reported here for the first time. The evidences from karyotyping, DNA content analysis and nuclear volume measurements were described to confirm the hexaploid nature of the identified individual.
