    Physical mapping of 5S rDNA reveals a new locus on 3R and unexpected complexity in a rye translocation used in chromosome mapping (1994)

    Notes: Abstract Using fluorescence in situ hybridization (FISH) with probe pScT7, three different 5S rDNA loci were detected in the satellite of rye chromosome 1R (5SDna-R1) and in the short arms of chromosomes 3R (5SDna-R3) and 5R (5SDna-R2) respectively. All three loci showed polymorphism for the hybridization signal intensity. In order to determine the localization of these rye 5S rDNA multigene loci with higher precision within the corresponding chromosome arms, the probe pScT7 was physically mapped by FISH in relation to the following five translocations (Wageningen Tester Set): T850W (1RS/4RL), T248W (1RS/6RS), T273W (1RS/5RL), T305W (2RS/5RS) and T240W (3RS/5RL). Accurate physical maps of the translocation breakpoints had previously been made using electron microscope analysis of spread pachytene synaptonemal complexes of heterozygotes for the different translocations. The results indicate that locus 5SDna-R3 is located between the breakpoint of translocation T240W and the telomere, whereas locus 5SDna-R2 is located between the breakpoint of translocation T305W and the centromere, the hybridization of probe pScT7 on T305W translocated chromosomes demonstrating the complex nature of this translocation. On the other hand, the simultaneous detection of probes pScT7 and pTA71 (18S-5.8S-26S rDNA) with two different fluorochromes, indicated that the breakpoints of translocations T850W and T248W are located between loci Nor-R1 and 5SDna-R1.

    Physical mapping of translocation breakpoints in rye by means of synaptonemal complex analysis (1994)

    Notes: Abstract A physical map including 40 translocation breakpoints has been constructed in rye by means of synaptonemal complex (SC) analysis of well-paired pachytene quadrivalents. The chromosome arms involved in such translocations were previously identified either from mitotic C-banding analysis or from the meiotic configurations observed in the progenies of crosses with a rye line having multiple chromosome rearrangements. The synaptonemal complexes formed by some translocation homozygotes were also analyzed, the relative pachytene SC length of their translocated chromosomes being compared to that observed in the corresponding translocation heterozygotes. In the translocations in which the position of the breakpoint could be well defined from mitotic C-banding analysis, a good correspondence between the relative position of the point showing partner exchange in the pachytene quadrivalents and the actual location of the breakpoint was established. It is concluded that the mapping of translocation breakpoints by SC analysis of pachytene quadrivalents provides a more accurate estimate of the position of the breakpoints than that obtained from mitotic C-banding analysis, due to the lack of evenly-distributed interstitial C-bands in most rye chromosomes. The distribution of the breakpoints along the chromosomes in relation to their spontaneous or induced origin is also discussed.

    A cytogenetic map on the entire length of rye chromosome 1R, including one translocation breakpoint, three isozyme loci and four C-bands (1993)

    Notes: Summary A cytogenetic map of the whole 1 R chromosome of rye has been made, with distances between adjacent markers shorter than 50% recombination. Included in the map are isozyme loci Gpi-R1, Mdh-R1 and Pgd2, the telomere C-bands of the short arm (ts1) and the long arm (tl1), two interstitial C-bands in the short arm proximal to the nuclear organizing region (NOR) (is1) and in the middle of the long arm (il1), respectively, and translocation T273W (Wageningen tester set). By means of electron microscope analysis of spread pachytene synaptonemal complexes, the breakpoint of this translocation was physically mapped in the short arm of 1R, proximal to NOR, and in the long arm of 5R (contrary to previous assumptions). The data indicated the marker order: ts1 — Gpi-R1 — is1 — T273W/Mdh-R1 — il1 — Pgd2 — tl1. A comparison between genetic and physical maps revealed that recombination is mainly restricted to the distal regions of both arms. For the translocation T273W, in heterozygotes no recombinants were observed between the translocation breakpoint and its two adjacently located markers (is1 and Mdh-R1), but recombination was not reduced in the distal regions of the chromosome. The segregations of several other isozyme and C-band markers also analyzed in the investigation presented here were consistent with observations of earlier authors concerning chromosome asignment and linkage relationships.

    Notes: Abstract In order to reach a higher accuracy concerning the cytological locations of the rye seed storage protein lociSec2[Gli-R2] andSec3[Glu-R1] located within chromosome arms 2RS and 1RL, respectively, the linkage relationships between the following loci were analyzed: isozyme lociGpi-R1,Mdh-R1, andPgd2, translocationT273W (Wageningen tester set, involving chromosome arms 1RS and 5RL), the telomere C-bands of chromosome arms 1RL (tL1), 2RS (tS2), and 5RS (tS5), and three interstitial C-bands in chromosome arm 1RS (iS1), in the middle of chromosome arm 1RL (iL1), and in the middle of chromosome arm 2RL (iL2), respectively. The data indicated that locusSec3 is located in the distal half of chromosome arm 1RL (between C-bandiL1 and locusPgd2), while locusSec2 is located a short distance (2.9 ± 1.4%) from the telomere C-band of chromosome arm 2RS.

    Notes: Abstract Cytogenetic maps involving chromosomes 1R, 3R, 4R and 6R have been developed from the analysis of offspring of crosses between multiple heterozygous rye plants. The maps include isozyme loci GpiR1, Mdh-R1 and Pgd2 (located in chromosome 1R), Mdh-R2 (located in chromosome 3R), Pgm-R1 (located in chromosome 4R) and Aco-R1 (located in chromosome 6R). Various telomeric and interstitial C-bands of these four chromosomes, the centromere split of chromosome 3R, and translocation TR01 were used as cytological markers. By means of electron microscope analysis of spread pachytene synaptonemal complexes, the breakpoint of TR01 was physically mapped in chromosome arms 4RS and 6RL. From the linkage data, conclusions were derived concerning the cytological locations of the isozyme loci and the physical extent of the evolutive translocations involving chromosome arm 6RL.
