    Development of STS markers closely linked to the Ppd-H1 photoperiod response gene of barley (Hordeum vulgare L.) (2000)

    Notes: Abstract  A BC2 population of 353 plants segregating for the Ppd-H1 photoperiod response gene was developed from a cross between the winter barley ’Igri’ and the spring barley ’Triumph.’ Bulk segregant analysis identified six AFLP markers closely linked to the Ppd–H1 gene and three strongly amplified AFLP bands that mapped 0.8-cM distal, 0.6-cM proximal and 2.3-cm proximal to Ppd-H1 were cloned and sequenced. Southern-blot analysis showed that the cloned fragments were single-copy sequences in ’Igri’, the variety from which they were derived. Two of the sequences were absent from ’Triumph’ while the third detected a single-copy sequence. The cloned fragments were used to design specific sequence tagged site (STS) primer pairs to assist in the construction of a high-resolution map of the Ppd-H1 region.

    Organization of retro-element and stem-loop repeat families in the genomes and nuclei of cereals (1995)
    Springer
    Chromosome research 3 (1995), S. 5-15 
    Details
    ISSN: 1573-6849
    Keywords: Interphase ; physical organization ; repeated sequences
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Sequences homologous to the retro-element BIS-1 and the stem-loop repeat Hi-10 are present in the genomes of a number of cereal species. A detailed characterization of these elements indicated that they are non-randomly organized in the genomes of at least two of these species, namely barley and rye. In contrast to the BIS-1 retro-elements, the stem-loop repeats are also non-randomly organized into discrete domains in interphase nuclei from barley and rye. Features of the organization of these repeats along chromosomes and within interphase nuclei of rye, barley and rice are discussed.

    Fluorescent in situ hybridization as an aid to introducing alien genetic variation into wheat (1955)
    Springer
    Euphytica 85 (1955), S. 275-279 
    Details
    ISSN: 1573-5060
    Keywords: alien introduction ; fluorescent in situ hybridization (FISH) ; wheat
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Fluorescent in situ hybridization (FISH) has been used to assess the occurrence and frequency of wheat-alien chromosome pairing in a wheat/Thinopyrum bessarabicum hybrid and in wheat/rye hybrids with different levels of chromosome pairing by examining pollen mother cells at metaphase I of meiosis. The use of FISH to identify the presence and size of alien chromatin in a wheat background is also demonstrated. The value of FISH as an aid to the introgression of alien genetic variation into wheat is discussed.
