    The effects of managanese and nitrate supply on the levels of phenolics and lignin in young wheat plants (1984)
    Springer
    Plant and soil 81 (1984), S. 437-440 
    Details
    ISSN: 1573-5036
    Keywords: Lignin ; Manganese ; NO 3 − Phenols ; Triticum aestivum

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Managanese deficiency (〈 18 μg g−1 Mn) resulted in decreased levels of phenols in wheat shoots and decreased levels of lignins in both roots and shoots. These observed reductions in phenol contents was due largely to a decrease in the alkaline labile phenol component. Levels of nitrate supplied in solution influenced both phenol and lignin production; high nitrate levels (15 mM) resulted in a reduction in phenol and lignin in the shoot but stimulated lignin production in root tissue.

    Characterization of the multigene family coding for HMW glutenin subunits in wheat using cDNA clones (1983)
    Springer
    Theoretical and applied genetics 67 (1983), S. 87-96 
    Details
    ISSN: 1432-2242
    Keywords: HMW glutenin subunit genes ; cDNA clones ; Tandem DNA repeats ; Chromosomal location ; Gene copy number ; Wheat ; Triticum aestivum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary cDNA clones encoding wheat HMW glutenin subunits have been isolated from a cDNA bank made to poly A+ RNA from developing wheat endosperm var. Chinese Spring. One such clone, pTag 1290, has enabled us to identify the HMW glutenin mRNA species. The DNA sequence of this clone has been partially determined and it contains several tandem DNA repeats. The sequence is discussed in relation to the generation of the HMW glutenin subunit gene family. Analysis of the organization of the HMW glutenin sequences in the wheat genome revealed that the genes encoding HMW glutenin subunits exist in low copy number and are located on the long arm of each of the homoeologous group 1 chromosomes.

    Notes: Summary Triple-labelled nutrient solution was used to compare the effects of seven root-infecting fungi on uptake of K, Ca and P by wheat. Plants grown in sand or hydroponic culture were transferred to solutions that contained42K,45Ca and32P for 24 h, then dried, ashed and digested in 6M HCl. To distinguish radiation emitted by42K,45Ca and32P plant digests were counted on two channels of a liquid scintillation counter immediately and 7 days later, after the decay of42K radiation. Plants infected byGaeumannomyces graminis took up and translocated less K, Ca and P to their shoots than uninfected plants. Other root-infecting fungi had little effect on uptake of these ions.

    A role for managanese in the resistance of wheat plants to take-all (1984)
    Springer
    Plant and soil 78 (1984), S. 441-444 
    Details
    ISSN: 1573-5036
    Keywords: Gaeumannomyces graminis vartritici ; Hay-die ; Manganese deficiency ; Take-all ; Triticum aestivum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The hypothesis that wheat plants deficient in managenese are predisposed to infection byGaeumannomyces graminis is outlined, and a test of the hypothesis in a soil system is reported. The results supported the hypothesis: wheat plants growing in managanese-deficient soil, although not showing foliar symptoms, were markedly more susceptible to infection; plant analysis confirmed the nutrient status of the plants. A review of the literature on take-all in wheat coupled with the results of our experiments suggests a reinterpretation of the etiology of this disease, since those edaphic factors which promote infection by this organism are those which also render managese unavailable to the host. Managenese nutrition is proposed as a common factor in many of the environmental conditions which influence the host-pathogen balance.

    Notes: Summary Using monosomic analysis genes governing resistance in one wheat variety, ‘E5883’, against stem rust races 15C and 122, were located on specific chromosomes. Against race 15C, a major dominant gene, Sr6, was located on chromosome 2D of ‘E5883’ with minor modifiers found on chromosomes 4A and 6D. Against race 122, the presence of a recessive hemizygous ineffective gene, Sr8, was identified, located on chromosome 6A of variety ‘E5883’.

    The genetic control of grain esterases in hexaploid wheat (1984)
    Springer
    Theoretical and applied genetics 68 (1984), S. 219-226 
    Details
    ISSN: 1432-2242
    Keywords: Hexaploid genotypes ; Allelic variation ; Esterase ; Isozymes ; Isoelectric focusing ; Wheat
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Analysis of grain esterase isozymes in Chinese Spring aneuploid genotypes by IEF confirmed that genes on the long arms of chromosomes 3A, 3B and 3D (Est-5) control the production of 19 isozymes. Allelic variants have been found for the isozyme pattern controlled by each chromosome. Segregational data involving null alleles and complex phenotypic differences indicate that the wheat grain esterases are encoded by three compound and probably homoeoallelic loci, each capable of producing at least six different isozymes. In a sample of 138 hexaploid genotypes, seven alleles were distinguished.

    The Tom Thumb dwarfing gene, Rht3 in wheat, I. Reduced pre-harvest damage to breadmaking quality (1982)
    Springer
    Theoretical and applied genetics 62 (1982), S. 121-126

    ISSN: 1432-2242
    Keywords: Wheat ; Quality ; Dwarfism ; Gibberellin ; α-amylase
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The effects of the Tom Thumb dwarfing gene, Rht3, on the quality and quantity of grain α-amylase produced during germination and by induction with exogenous gibberellic acid are described. In a season conducive to high sprouting damage the gene reduced α-amylase levels in the field by 77%. Selection among random Rht3 genotypes showed that other genetic factors can be combined with the dwarfing gene to further increase sprouting damage resistance.

    ISSN: 1432-2242
    Keywords: Triticum aestivum ; Grainprotein ; Gene action ; Regression ; Diallel cross
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Diallel crosses between five divergent vulgare wheat cultivars were made in order to evaluate the mode of inheritance and combining ability of grain proteins. Significant differences in grain protein content were found between cultivars and their hybrids. It was established that the inheritance of seed protein in the F1 generation included both additive and non-additive gene action.

    Preferential C-banding of wheat or rye chromosomes (1982)
    Springer
    Theoretical and applied genetics 63 (1982), S. 227-233

    ISSN: 1432-2242
    Keywords: C-banding ; Wheat ; Rye ; Triticale
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Using different stains, wheat chromosomes could be distinguished from rye chromosomes by preferential staining. C-bands of rye chromosomes were preferentially stained with Giemsa while those of wheat chromosomes were preferentially stained with either Leishman or Wright stain. Preferential staining aids the identification of wheat and rye chromosomes and chromosome segments and in particular the recognition of wheat/rye chromosome substitutions and translocations.

    Study on nuclear and cytoplasmic genome expression in wheat by two-dimensional gel electrophoresis (1984)
    Springer
    Theoretical and applied genetics 68 (1984), S. 335-345

    ISSN: 1432-2242
    Keywords: Triticum aestivum ; 2D electrophoresis ; Developmental genetics ; Cytoplasmic inheritance ; Genetic regulation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    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.
