    Notes: Summary Two-dimensional gel electrophoresis of denaturated proteins were performed at five developmental stages or organs (hereafter referred to as stage-organs) on two wheat lines with four different cytoplasms. Five hundred and fifty to 712 reproducible spots were scored depending on the stage-organ. Each stage-organ is unambiguously characterized and several types of control of protein quantity are recorded. Post-translational modifications are hypothetized and may sometimes be stagespecific. Two cytoplasmic patterns are found: one for the euplasmic lines with Triticum aestivum cytoplasm and one for the alloplasmic lines with Aegilops juvenalis, Ae. ventricosa and Ae. kotschyi cytoplasms. Cytoplasmic variation is observed for 28 spots showing position difference, all of which are probably products of the LS gene, and for four spots showing differences for regulation of protein quantity. Nuclear variation between ‘Chinese Spring’ and ‘Selkirk’ is found for 20 allelic differences and for 20 regulatory systems, the latter number being probably underestimated.

    Blocks of gliadin components in winter wheat detected by one-dimensional polyacrylamide gel electrophoresis (1984)
    Springer
    Theoretical and applied genetics 67 (1984), S. 559-568

    ISSN: 1432-2242
    Keywords: Triticum aestivum ; Gliadins ; Electrophoresis ; Hybridological analysis ; Genetic nomenclature

    Topics: Biology
    Notes: Summary Inheritance of gliadin components in winter wheat has been studied by one-dimensional polyacrylamide gel electrophoresis. Single F2 grains from 36 intervarietal hybrid combinations have been analysed. The genetic analysis has revealed blocks, including 1–6 gliadin components, which are inherited as individual mendelian traits. About 80 variants of blocks have been detected. On the basis of the allelism test they are grouped into 6 series in accordance with the number of known gliadin-coding loci located on chromosomes of the homoeologous groups 1 and 6. Each series includes 8–18 blocks controlled by different alleles of one gliadin-coding locus. Blocks of components have been confirmed to be inherited codominantly in accordance to the gene dose in the triploid endosperm. The highest similarity between members of one series is observed in groups of blocks controlled by chromosomes ID and 6D. On the contrary, many blocks controlled by chromosomes 1A and 1B have no bands in common. The presented catalogue of blocks of components may be used to make up gliadin genetic formulae and to compare electrophoregrams obtained by different authors. Blocks of gliadin components are suitable genetic markers for use in revealing and studying heterogeneity of wheat varieties, in tracing their origin, in identifying recombinations, translocations and substitutions of the genetic material and in solving many other problems of the origin, evolution and selection of hexaploid wheat.

    Analysis of nucleolar activity in Agropyron elongatum, its amphiploid with Triticum aestivum and the chromosome addition lines (1984)

    Keywords: Amphiplasty ; Ag-NOR ; Addition lines ; Nucleolar organizer ; Agropyron elongatum ; Triticum aestivum

    Topics: Biology
    Notes: Summary The nucleolar organizer activity of the Agropyron elongatum, its amphiploid with hexaploid wheat (Triticum aestivum) and the chromosome addition lines is analyzed by the silver-staining procedure. Four Ag-NORs are observed in A. elongatum corresponding to the chromosomes 6E and 7E. In the amphiploid T. aestivum — A. elongatum, eight Ag-NORs are observed which corresponds the wheat chromosomes 1B and 6B and to the elongatum chromosomes 6E and 7E. Thus, there is codominance in the nucleolar organizer activity of the chromosomes of the two species. However, a partial amphiplasty is detected since less than 8 Ag-NORs (7 up to 4) are observed in some metaphase cells; the chromosomes 6E and 7E are occasionally suppressed by wheat chromosomes. This conclusion is confirmed by the behaviour of the addition lines since only in those corresponding to the chromosomes 6E and 7E are the elongatum chromosomes nucleolar active although occasionally they can be suppressed by wheat chromosomes.

    The meiotic pairing of nine wheat chromosomes (1984)

    Notes: Summary The meiotic identification of nine pairs of chromosomes at metaphase I of meiosis of Triticum aestivum (B genome, 4A and 7A) has been achieved using a Giemsa C-banding technique. As a result, the analysis of the pairing of each chromosome arm in disomic and monosomic intervarietal hybrids between ‘Chinese Spring’ and the Spanish cultivar ‘Pané 247’ could be carried out. Differences in the chiasmata frequencies per chromosome arm cannot be explained on the basis of relative arm lengths only. Possible effects of arm-to-arm heterochromatic differences on meiotic pairing are discussed.

    ISSN: 1432-2242
    Keywords: Triticum aestivum ; Gliadins ; Two-dimensional electrophoresis ; Hybridological analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Blocks of gliadin components found both in a number of varieties and in single F2 grains of winter wheat intervarietal hybrids have been studied by two-dimensional electrophoresis combining electrophoresis in acidic aluminium-lactate buffer (pH3.1) and SDS-electrophoresis. Gliadin components (spots) have been shown to be inherited as linked groups (blocks), codominantly and in accordance with a gene dosage in triploid endosperm. Blocks include components differing in their electrophoretic mobility and molecular weight. Some allelic variants of blocks differ only in presence of few additional components or in the electrophoretic mobility of components with similar molecular weights; other variants may contain no similar components. Apparently, in the course of evolution, mutations in individual genes of gliadin-coding loci and processes changing the number of expressing genes and the sizes of their structural part occurred.

    Notes: Abstract The relationships of three wheat-Aegilops longissima chromosome addition lines A, C, and D with homoeologous wheat chromosomes were studied in PMC meiosis. Substitutions of alien chromosome A for wheat chromosome 6 B, chromosome C for 1 B and chromosome D for 4 B were obtained. The production of 4 BS/C and 7 BS/D chromosome translocations indicated cytogenetic relationships of C partially to homoeologous wheat chromosomes of group 1 and 4, and D partially to homoeologous wheat chromosomes of group 4 and 7.

    Yield responses by modern wheat genotypes to phosphate fertilizer and their implications for breeding (1984)
    Springer
    Euphytica 33 (1984), S. 81-89 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; wheat ; grain yield ; phosphate response ; height ; harvest index
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The response to phosphate fertilizer by modern wheat genotypes was examined in the field under natural rainfall in three seasons. Models were developed which show that grain yield was positively correlated with biological yield and harvest index. In one of the seasons, which was relatively dry, shorter statured wheats gave higher yields at each level of applied phosphate. Higher levels of phosphate tended to offset the reduction in yield associated with late heading and the importance of biological yield on grain yield. The genotypes which produced the largest number of grains m-2 produced the highest yields. Implications for plant breeding programs are discussed.

    Genetic and cytogenetic studies with a male sterile mutant of common wheat (Triticum aestivum) (1984)

    Notes: Summary Genetic and cytogenetic studies were done on a male sterile mutant of the wheat variety ‘Probus’. Association of the 4A chromosome carrying the ms gene was studied in the F1 of the male sterile ‘Probus’ with ‘Chinese Spring’ ditelo 4AS, with ‘Transec’ and with line ‘T4AS-DRS’ respectively. The presumption that the genetic male sterility of the mutant was due to a terminal deletion of the short arm of chromosome 4A could be confirmed. Linkage studies showed that the ms gene was at 17 map units from the dwarfing gene (Rht3) of ‘Minister dwarf’. This allows selection of short male sterile plants at the seedling stage.

    Notes: Summary The high-molecular-weight subunits of glutenin from wheat 1R(1B) substitution and 1BL/1RS translocation lines were fractionated by SDS-PAGE. Two new subunits denoted R1 and R2 were characterized in 1R(1B) substitution, but not in 1BL/1RS translocation lines. R1 and R2 were proved to be rye proteins by 2d electrophoresis (NEPHGE x SDS-PAGE). In contrast to literature citations it was demonstrated that the cultivar Winnetou is a 1R(1B) substitution line and the cultivars Clement and Mildress both are 1BL/1RS translocation lines.
