    The recursive structure of some ordering problems (1991)

    Notes: Abstract Some classical ordering problems (sorting, finding the maximum, finding the maximum and the minimum, finding the largest and the next largest, merging, and finding the median) are considered from a recursive viewpoint. IfX(n) denotes an instance of sizen of any one of these problems thenX(n) can be solved by finding the solution to a number ξ(n,k) of problemsX(k) for some fixedk; ξ(nk,k) is called therelative complexity. Upper and lower bounds on the relative complexity are found. For the problem of finding the maximum, finding the maximum and the minimum, and finding the largest and the next largest these bounds are optimal.

    RFLP-based genetic map of rye (Secale cereale L.) chromosome 1R (1991)

    Notes: Summary A map of chromosome 1R of rye was constructed using 16 molecular and biochemical loci. From long arm to short arm, known-function loci were placed in the order: XAdh — XLee — Glu-R1[Sec-3] — XPpdk-1R — XEm-1R-1 — XEm-1R-2 — Centromere — XNor-R1 —Gpi-R1 — XGli-R1 [Sec-1a] along with six anonymous genomic and cDNA clones from wheat. The map, which spans 106 cM with 12 loci clustered in a 15-cM region around the centromere, shows reasonably good agreement with previously published maps for the centromeric region, whereas the XNor-R1 — Gpi-R1 region gives a much larger distance than previously reported.

    Chromosomal rearrangements in the rye genome relative to that of wheat (1993)
    Springer
    Theoretical and applied genetics 85 (1993), S. 673-680

    ISSN: 1432-2242
    Keywords: Translocations ; Rye ; RFLP ; Genetic maps ; Comparative mapping ; Co-linearity

    Topics: Biology
    Notes: Summary An RFLP-based genetic map of Secale Cereale has provided evidence for multiple evolutionary translocations in the rye genome relative to that of hexaploid wheat. DNA clones which have previously been mapped in wheat indicated that chromosome arms 2RS, 3RL, 4RL, 5RL, 6RS, 6RL, 7RS and 7RL have all been involved in at least one translocation. A possible evolutionary pathway, which accounts for the present day R genome relative to the A, B and D genomes of wheat, is presented. The relevance of these results for strategies designed to transfer useful genes from rye, and probably other related species, to wheat is discussed.

    Nonhomoeologous translocations between group 4, 5 and 7 chromosomes within wheat and rye (1992)

    Notes: Summary Genetic maps of wheat chromosome 4A and rye chromosome arm 5RL, and the chromosomal locations of 70 sets of isozyme and molecular homoeoloci have been used to further define the structure of wheat chromosomes 4A, 5A and 7B, and rye chromosomes 4R, 5R and 7R. We provide evidence, for the first time, which is consistent with the presence of an interstitial segment on 4AL originating from 5AL, and of a segment originally from 5RL on 7RS. The evolutionary origins of the present chromosomes are discussed.
