ABSTRACT The genetic control of major wheat endosperm proteins by homoeologous group 1 chromosomes has been studied by two-dimensional polyacrylamide gel electrophoresis. The control of at least 15 distinct protein subunits or groups of protein subunits has been allocated to chromosomes 1A, 1B and 1D of Chinese Spring wheat from the analysis of grains of aneuploid genotypes. In addition, six protein subunits have been shown to be controlled by chromosome 1Cu of the related species, Aegilops umbellulata, from studies of wheat lines carrying disomic substitutions of 1Cu chromosomes. On the basis of protein subunit patterns, chromosome 1Cu is more closely related to chromosome ID of wheat than to chromosomes 1A or 1B.

A collection of 19 wheat (Triticum aestivum) probes, detecting sequences in the seven homoeologous groups of chromosomes, were hybridized to DNA from the 'Kanota' series of oat monosomic lines (Avena byzantina) to investigate their use for identifying groups of homoeologous oat chromosomes. Three probes from homoeologous group 1 of wheat, psr161, psr162, and psr121, mapped among the set of oat chromosomes 1C, 14, and 17. One homoeologous group 6 probe, psr167, mapped to oat chromosomes 1C and 17. Two oat probes that had previously been shown to map to oat chromosomes 1C, 14, and 17 were then hybridized to DNA from the 'Chinese Spring' wheat ditelosomics. They localized to homoeologous group 1 wheat chromosomes, one to the short arm and one to the long arm. These results reveal that in hexaploid oat there is a group of three chromosomes that correspond at least in part to homoeologous group 1 of wheat. The remaining wheat probes identifying other wheat homoeologous sets did not detect a complete series of homoeologous chromosomes in oat. This was presumably due to the incomplete status of the 'Kanota' monosomic series, chromosomal rearrangement in Avena, weak hybridization signals owing to low probe-target sequence homology, and (or) detection of only two hybridization bands by the wheat probe.Key words: oat, RFLPs, aneuploids, wheat, homoeologous groups.

AbstractThe short arm of Triticeae homeologous group 1 chromosomes is known to contain many agronomically important genes. The objectives of this study were to physically localize gene-containing regions of the group 1 short arm, enrich these regions with markers, and study the distribution of genes and recombination. We focused on the major gene-rich region (“1S0.8 region”) and identified 75 useful genes along with 93 RFLP markers by comparing 35 different maps of Poaceae species. The RFLP markers were tested by gel blot DNA analysis of wheat group 1 nullisomic-tetrasomic lines, ditelosomic lines, and four single-break deletion lines for chromosome arm 1BS. Seventy-three of the 93 markers mapped to group 1 and detected 91 loci on chromosome 1B. Fifty-one of these markers mapped to two major gene-rich regions physically encompassing 14% of the short arm. Forty-one marker loci mapped to the 1S0.8 region and 10 to 1S0.5 region. Two cDNA markers mapped in the centromeric region and the remaining 24 loci were on the long arm. About 82% of short arm recombination was observed in the 1S0.8 region and 17% in the 1S0.5 region. Less than 1% recombination was observed for the remaining 85% of the physical arm length.
