Oryza meyeriana is highly resistant to rice bacterial blight (BB) and this resistance trait has been transferred to cultivated rice (O. sativa) using asymmetric somatic hybridization. However, no resistance genes have yet been cloned. In the present study, a progeny of the somatic hybridization with high BB resistance was crossed with a rice cultivar with high BB susceptibility to develop an F2...
We have used purified mouse immunoglobulin light chain mRNA and synthetic DNA which is complementary to it to assess the reiteration frequency of gene sequences corresponding to the kappa constant region of the mouse immunoglobulin light chain. These studies indicate that the constant region sequence is represented only two to three times per haploid mouse genome, a finding that rules out a sim...
A current approach to the investigation of the biochemical basis for neuronal function is the development, from neuroblastoma tumors, of clonal cell lines which grow rapidly in cell culture but which retain the ability to express one or more characteristics of differentiated neurons. These characteristics may be morphological (1-3), biochemical (1, 4), or physiological (5-8). Recently, it has b...
Synapsin I is a neuron-specific phosphoprotein associated with the membranes of small synaptic vesicles. Its function is not entirely clear, but evidence points to a possible role in the regulation of neurotransmitter release. Its biosynthesis is under developmental control. Assignment of the human synapsin I gene to the X chromosome at band Xp11 was accomplished by in situ hybridization, using...
The ability of the antineoplastic agent epirubicin to induce aneuploidy and meiotic delay in the somatic and germinal cells of male mice was investigated by fluorescence in situ hybridization assay using labeled DNA probes and BrdU-incorporation assay. Mitomycin C and colchicine were used as positive controls for clastogen and aneugen, respectively, and these compounds produced the expected res...
