SOURCE AND DESCRIPTION OF CLONE: A 1.65 kb ECORI cDNA insert corresponding to the full length hepatic lipase (HL) sequence isolated from a rat liver cDNA library (I). CHROMOSOMAL LOCALIZATION: Chromosome 15q21 by somatic cell and in situ hybridization (2).
The repetitive DNA sequences of the newt, Triturus viridescens, have been studied by nucleic acid hybridization procedures. Complementary RNA was synthesized enzymatically from unfractionated newt DNA. This RNA hybridized strongly to the centromeric regions of both somatic and lampbrush chromosomes It also bound to other loci scattered along the lengths of the chromosomes The amplified ribosoma...
In an attempt to remove lethal and deleterious genes and enhance the heterozygosity of the potato genome, we developed several diverse somatic hybrids through the electrofusion of selected monoploids. Somatic hybrids and somaclones resulting from fused and unfused protoplasts, respectively, were verified with microsatellites. Molecular markers anchored in the Tst1 retrotransposon were used to e...
A broad spectrum of genetic and epigenetic changes is induced by wide hybridization and subsequent polyploidization, but the timing of these events remains obscure because early hybrid cells are very difficult to harvest and analyze. Here, we used both cytological and genetic marker approaches to analyze the constitution of very young somatic hybrid cells between japonica rice (Oryza sativa L. ...
Two different mapping approaches were used to determine the human chromosomal location of the gene for protein S. A human protein S cDNA was used as a hybridization probe to analyze a panel of somatic cell hybrids containing different human chromosomes. Cosegregation of protein S-specific DNA restriction fragments with human chromosome 3 was observed. Three cell hybrids containing only a portio...
