Chromosomal locations of eleven Elytrigia elongata (= Agropyron elongatum) isozyme structural genes

Chromosomal constitutions of five wheat – Elytrigia elongata partial amphiploids as revealed by GISH, multicolor GISH and FISH

A combination of meiotic pairing analysis and in situ hybridization (genomic in situ hybridization [GISH], multicolor GISH [mcGISH] and fluorescence in situ hybridization [FISH]) of five Triticum aestivum (Linnaeus, 1753) - Elytrigia elongata (Podpěra, 1902) (2n = 10x = 70) amphiploids was employed to investigate the genomic constitution and relationships between wheat and alien chromosomes. GI...

Determination of the Chromosomal Location of a Glutamate Oxaloacetate Transaminase Structural Gene Using Triticum-agropyron Translocations1

The glutamate oxaloacetate transaminase (GOT) zymogram phenotypes of a series of 15 translocation lines, a chromosome addition line and a chromosome substitution line were determined. In each of the translocation lines a segment of the long arm of Triticum aestivum chromosome 3D has been replaced by a portion of an Agropyron elongatum homoeologue. Evidence was obtained that the products of the ...

Chromosomal Locations of Genes That Control Wheat Endosperm Proteins

Chromosome Pairing in Hybrid Progeny between Triticum aestivum and Elytrigia elongata

In this study, the intergeneric hybrids F1, F2, BC1F1, BC1F2, and BC2F1 from Elytrigia elongata and Triticum aestivum crosses were produced to study their chromosome pairing behavior. The average E. elongata chromosome configuration of the two F1 hybrids agreed with the theoretical chromosome configuration of 21I+7II, indicating that the genomic constitution of this F1 hybrid was ABDStStEeEbEx....

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...
