    A molecular linkage map of rye (1996)
    Springer
    Theoretical and applied genetics 93 (1996), S. 1112-1118 
    Details
    ISSN: 1432-2242
    Keywords: Key words Genetic map ; RFLP ; RAPD ; Secale cereale ; Triticum aestivum

    Topics: Biology
    Notes: Abstract A genetic map of six chromosomes of rye, (all of the rye chromosomes except for 2R), was constructed using 77 RFLP and 12 RAPD markers. The map was developed using an F2 population of 54 plants from a cross between two inbred lines. A rye genomic library was constructed as a source of clones for RFLP mapping. Comparisons were made between the rye map and other rye and wheat maps by including additional probes previously mapped in those species. These comparisons allowed (1) chromosome arm orientation to the linkage groups to be given, (2) the corroboration of several evolutionary translocations between rye chromosomes and homoeologous chromosomes of wheat; (3) an increase in the number of available markers for target regions of rye that show colinearity with wheat. Inconsistencies in the location of markers between the wheat and rye maps were mostly detected by multi-copy probes.

    A comparative analysis of the genetic relationships between rye cultivars using RFLP and RAPD markers (1996)
    Springer
    Euphytica 88 (1996), S. 107-115 
    Details
    ISSN: 1573-5060
    Keywords: genetic relationships ; RAPD ; RFLP ; rye ; Secale cereale
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The genetic similarities of eight closely related rye cultivars were estimated using two molecular marking techniques: restriction fragment length polymorphism (RFLP) and random amplified polymorphic DNA (RAPD). Cultivars were evaluated for variation by 11 random cDNA and genomic clones used in combination with four restriction enzymes and 40 decamer primers. A total of 53 polymorphic RFLP fragments and 94 polymorphic RAPD fragments were observed. Based on the presence/absence of fragments, two genetic similarity matrices were calculated which were then used in cluster analysis. Differences between pair of cultivars were observed in RFLP and RAPD dendrograms. RFLP analysis produced estimates of genetic relationships more in accordance with the partially known pedigree of the cultivars than did RAPD analysis. The use of bulk samples of DNA in these analyses affected the sensitivity of RAPD assays more strongly. Dendrograms which took into account all fragments produced, either by RFLP or RAPD, reflected better the relationships between cultivars than did dendrograms based on only one type of marker. This reflects the importance of the number of markers used in determining the genetic relationships between genotypes.

    Sequential combinations of C-banding and in situ hybridization and their use in the detection of interspecific introgressions into wheat (1996)

    Notes: Summary The sequential combination of C-banding and in situ hybridization techniques applied in this or in a reverse order, are used to recognize targeted chromosomal regions in cereals. Both methods are described whereby standard chromosome squash preparations are followed by: i) C-banding technique using Leishman stain and a slightly modified in situ hybridization technique using biotin-labeled DNA probes, or ii) fluorescence in situ hybridization technique and C-banding. Both approaches have been successfully used onto mitotic chromosomes of rye and wheat resulting suitable for both their identification and detection of targeted sites.
