Chromosomal Locations of Genes That Control Wheat Endosperm Proteins

Chromosomal and plasmid locations for phosphoribulokinase genes in Alcaligenes eutrophus.

Genes coding for phosphoribulokinase (PRK), a key enzyme of the Calvin cycle, were localized in the genome of the chemoautotroph Alcaligenes eutrophus. The NH2-terminal sequence of the PRK subunit was determined. With a synthetic oligodeoxynucleotide probe complementary to a portion of this sequence, hybridization analysis revealed PRK genes to be located on both the chromosome and the megaplas...

Chromosomal location of the genes for human immunoglobulin heavy chains.

We have studied somatic cell hybrids between P3x63Ag8 mouse myeloma cells deficient in hypoxanthine phosphoribosyltransferase (EC 2.4.2.8) and either human peripheral lymphocytes or human lymphoblastoid or myeloma cells for the production of human immunoglobulin chains and for the expression of enzyme markers assigned to each of the different human chromosomes. Human chromosome 14 was the only ...

Locations of chromosomal proteins in polytene chromosomes.

D1, a nonhistone chromosomal protein rich in both basic and acidic amino acids, has been localized at a limited number of specific loci in polytene chromosomes of Drosophila melanogaster. H2B, a nucleosomal histone, and H1, a nonnucleosomal histone, are both found throughout most chromosomal regions.

Retrovirus-mediated insertion of expressed and non-expressed genes at identical chromosomal locations.

During retrovirus replication, a cellularly derived tRNA is annealed to the viral RNA at the primer binding site (PBS) to prime reverse transcription, and both the tRNA and the PBS become copied and matched together on complementary proviral DNA strands prior to integration. Using a viral PBS single base pair mutant which affects provirus expression in undifferentiated cells, we show that rever...
