The aneuploids of Chinese Spring wheat have been used to locate the genes(Ti-2) coding for a novel series of trypsin inhibitors to the long arms of the homoeologous group 5 chromosomes. Three allelic variants at the 5D locus were detected in a limited survey among wheat varieties, but no variation at the loci on either chromosome 5A or chromosome 5B was detected. Homoeoloci were found in a number of alien relatives, and in the majority of cases, these were present on the group 5 homoeologue…

Chromosomal location of genes controlling seed proteins in species related to wheat

The seed proteins of ‘Chinese Spring’ wheat stocks which possess single chromosomes from other plant species related to wheat have been separated by gel electrophoresis and support the idea that all these chromosomes are derived from a common ancestral chromosome and that they have maintained their integrity since their derivation from that ancestral chromosome.

Use of isozymes as chromosome markers in the isolation and characterization of wheat-barley chromosome addition lines

It was found that four disomic chromosome addition lines could be distinguished from one another and from the other three possible lines on the basis of the zymogram phenotypes of these isozymes.

Genetic control of shikimate dehydrogenase in hexaploid wheat

The genetics of shikimate dehydrogenase was investigated in Triticum aestivum cv Chinese Spring using the zymogram technique and indicated that the SKDH isozyme of faster electrophoretic mobility is encoded by a gene located in the p (= short) arm of chromosome 5A and that the products of two other genes encode two isozymes of slower and coincident electrophic mobility.

Intergenomic suppression of endosperm protein genes in common wheat

Total endosperm proteins from both several hexaploid wheat lines and their extracted tetraploid derivatives were fractionated on one-dimensional polyacrylamide gel electrophoresis, suggesting that D genome genes may suppress or effect the biosynthesis of these proteins.

The phenotype of wheat shows four bands, three of which are shown by aneuploid analysis to be controlled by the loci Dip-A1, Dip-B1 and Dip-D1 on chromosome arms 6AL, 6BL and 6DL, respectively.

Localization of Structural and Regulatory Genes for Phosphodiesterase in Wheat (TRITICUM AESTIVUM).

A complex interaction of the three genomes of wheat for regulation of PDE gene expression is revealed and it is shown that there are genes on group 5 chromosomes which positively control the expression of the 3D structural gene.

Allosyndetic recombination between a chromosome of Aegilops umbellulata and wheat chromosomes

Allosyndetic recombination was induced between chromosome 1U of Aegilops umbellulata and wheat chromosomes by producing plants monosomic for this alien chromosome and homozygous for the mutant ph1b

Genetic control of glucose phosphate isomerase in wheat and related species

GPI zymograms were used to identify homoeologous loci in chromosome additions of rye and Hordeum chilense to wheat, and to confirm the genotypes of chromosome substitutions of Aegilops umbellulata in wheat.

Localization to chromosomes of structural genes for the major protease inhibitors of barley grains

SummaryWheat-barley chromosome addition lines were compared by isoelectric focusing of protein extracts to identify chromosomes carrying loci for the major immunochemically distinct protease

Shikimate dehydrogenase – a biochemical marker for group 5 chromosomes in the Triticinae

This character provides a useful genetic marker for these previously unmarked chromosome arms, and the results support the notion of the conservation of gene synteny groups within the Triticinae.
