Abstract (sommario):

ABSTRACT The use of telomeric C-bands in wheat-rye hybrids has made it possible to distinguish three types of wheat-wheat (1BL) and wheat-rye associations (a, end-to-end extremely distal; b, end-to-ed distal; and c, interstitial) between homoeologous chromosomes at different metaphase I stages (early, middle and late) and also to estimate the actual recombination frequencies for such associations at anaphase I. There was a decrease of the a and b association frequencies during the different metaphase I stages, whereas the c type remained without variation in all stages. A good fit between the

Abstract (sommario):

Abstract Saccharomyces cerevisiae cells enter into a distinct resting state, known as stationary phase, in response to specific types of nutrient deprivation. We have identified a collection of mutants that exhibited a defective transcriptional response to nutrient limitation and failed to enter into a normal stationary phase. These rye mutants were isolated on the basis of defects in the regulation of YGP1 expression. In wild-type cells, YGP1 levels increased during the growth arrest caused by nutrient deprivation or inactivation of the Ras signaling pathway. In contrast, the levels of YGP1 a

The present study analyzed meiotic pairing in wheat – rye hybrids obtained by crossing of Triticum aestivum cv. Chinese Spring with allogamous ryes, two cultivars of Secale cereale ('Don Enrique' and 'Selectión') and Secale cereale ssp. segetale. The results indicate that each rye type has different behaviour on hybrid meiotic pairing because they contain distinct genetic systems affecting meiotic pairing. In the case of 'Don Enrique' and 'Selección,' a polygenic system could be present, but not identical in both cultivars. On the other hand, Secale cereale ssp. segetale contained genes that s

AbstractRye (Secale cerealeL.) is an exceptionally climate-resilient cereal crop, used extensively to produce improved wheat varieties via introgressive hybridization and possessing the entire repertoire of genes necessary to enable hybrid breeding. Rye is allogamous and only recently domesticated, thus giving cultivated ryes access to a diverse and exploitable wild gene pool. To further enhance the agronomic potential of rye, we produced a chromosome-scale annotated assembly of the 7.9-gigabase rye genome and extensively validated its quality by using a suite of molecular genetic resources.

Abstract (sommario):

Several hybrid combinations between rye and wheat ditelosomic for homoeologous group 3 or 5 chromosomes or mutant ph2b were used to analyze the effects of the rye genome and rye B-chromosomes on meiotic pairing. The results indicated that the rye Bs have an effect on bound-arm frequency, which varies with the wheat genotype. If wheat suppressors are absent, pairing decreases when Bs are added; whereas if wheat promoters are lacking, a pairing increase is observed in some hybrids with two rye Bs. There was thus an interaction between the genetic systems of the two parents, with the wheat parent

Perenniality, the ability of plants to regrow after seed set, could be introgressed into cultivated rye by crossing with the wild relative and perennial Secale strictum. However, studies in the past showed that Secale cereale × Secale strictum-derived cultivars were also characterized by reduced fertility what was related to so called chromosomal multivalents, bulks of chromosomes that paired together in metaphase I of pollen mother cells instead of only two chromosomes (bivalents). Those multivalents could be caused by ancient translocations that occurred between both species. Genetic studies

Abstract The most distinctive region of the rye B chromosome is a subtelomeric domain that contains an exceptional concentration of B-chromosome-specific sequences.

In this report we show that the two sequence families that have been previously found to make up the bulk of the domain have been assembled from fragments of a variety of sequence elements, giving rise to their ostensibly foreign origin

Abstract (sommario):

In situ hybridization with an interspersed repeat clone from rye, pSc119, was shown to be useful for detecting rye chromosomes introduced into wheat. However, since pSc119 also shows strong hybridization to a few sites in certain wheat chromosomes, small rye chromosome segments added to wheat may be difficult to detect. In this study, detection of rye chromosomes present in triticale and triticale × wheat hybrids was accomplished with the use of a subfragment from pSc119 (pSc119.1) whose sequence is dispersed throughout the rye chromosomes and only weakly cross-hybridizes to a few telomeric an

Abstract (sommario):

Complete genomic and cDNA sequences of the Waxy gene encoding granule-bound starch synthase I (GBSSI) were isolated from the rye genome and characterized. The full-length rye Waxy genomic DNA and cDNA are 2767 bp and 1815 bp, respectively. The genomic sequence has 11 exons interrupted by 10 introns. The rye Waxy gene is GC-rich, with a higher GC frequency in the coding region, especially in the third position of the codons. Exon regions of the rye Waxy gene are more conserved than intron regions when compared with the homologous sequences of other cereals. The mature rye GBSSI proteins share m

Abstract This study evaluated the effect of processing method and severity of hybrid fall rye on dry matter intake (DMI), ruminal fermentation, and apparent total tract nutrient digestibility for beef cattle. Ruminally cannulated Simmental heifers (n = 8; 327±33 kg) were used in a replicated 4×4 Latin square (21-d periods) balanced for carry-over effects with a 2×2 factorial treatment. Tempered rye [water added to achieve 80% dry matter (DM)] was compared with dry-rolled rye. Roller gap width of 1.23-mm and 0.8-mm were used for coarse and finely processed rye, respectively.

Abstract (sommario):

A novel type of polymerase chain reaction (PCR) marker was developed for the mapping of cereal rye (Secale cereale). Primer pairs were synthesized targeting the insertion sites of three individual copies of the R173 family of rye specific repeated DNA sequences. While one primer was derived from a sequence within the respective R173 element, the second primer corresponded to a flanking region. The complex banding patterns obtained in rye allowed not only the mapping of the three R173 elements to certain chromosome regions of 1RS (the short arm of rye chromosome 1) but also the mapping of an ad

Abstract (sommario):

A diminutive rye chromosome (midget) in wheat was used as a model system to isolate a highly reiterated centromeric sequence from a rye chromosome. Fluorescence in situ hybridization (FISH) shows this sequence localized within all rye centromeres and no signal was detected on wheat chromosomes. DNA sequencing of the repetitive element has revealed the presence of some catalytic domains and signature motifs typical of retrotransposon genes and has been called the Bilby family, representing a diverged family of retrotransposon-like elements. Extensive DNA database searching revealed some sequenc

NBS-LRR-type disease resistance gene-like cDNA, induced by salicylic acid (SA) was cloned from rye Secalecereale L. (2n = 14RR) var. Petkus, which has rust resistance genes such as Lr26, Sr31 andRr9. We designed primers based on the NBS region and performed PCR using Petkus genomic DNA as a template. Next, we TA-cloned a 532-bp DNA fragment containing five homologous amino acid sequences in the NBS region. The SA-treated rye showed strong expression of a transcript of approximately 3.5 knt in the Northern blots probed with the NBS fragment; however, no transcripts were observed with the untrea

Abstract Saccharomyces cerevisiae cells enter into the G0-like resting state, stationary phase, in response to specific types of nutrient limitation. We have initiated a genetic analysis of this resting state and have identified a collection of rye mutants that exhibit a defective transcriptional response to nutrient deprivation. These transcriptional defects appear to disrupt the control of normal growth because the rye mutants are unable to enter into a normal stationary phase upon nutrient deprivation. In this study, we examined the mutants in the rye1 complementation group and found that r

An attempt was made to determine the inheritance of the rye genes which induce high chiasma frequency in hybrids with wheat and to study if the ability of rye to induce partial amphiploidy in hybrids with wheat was heritable. Five to eight F2 pollen plants were derived from seeds taken from each of three F1 plants that had given high chiasma frequency in hybrids with 'Chinese Spring' wheat in earlier studies. Similarly, six to seven F2 pollen plants were derived from each of three F1 plants that had given partial amphiploids in hybrids with 'Chinese Spring' wheat in earlier studies. Chiasma fr

Abstract (sommario):

A novel family of highly repeated sequences on the B chromosome of rye (Secale cereale) has been identified. The D1100 family has not been detected on the rye A chromosomes and shows little or no homology to any previously described repeat sequence in rye. In addition, different rye species, and different B chromosomes within the same species, show significant heterogeneity in the arrangement of the D1100 sequences. An EcoRI clone of a member of the family has been obtained. These results provide direct evidence for the organisation and nature of the B-chromosome DNA in rye, and they are discu

Abstract (sommario):

The expression of aluminum tolerance from rye (Secale cereale L.) when present in a wheat (Triticum aestivum L. em. Thell.) background has been observed to be much lower than that in rye itself. By crossing each of the ditelocentric lines of 'Chinese Spring' wheat with a tolerant rye, the effects of the presence or absence of each arm of wheat on the expression of rye aluminum tolerance could be established. Of 42 wheat chromosome arms, 18 affected the expression of rye aluminum tolerance. Tolerance was increased over that observed in the euploid wheat–rye hybrid when arms 4AL, 5AL, 6AL, 7BS,

An analysis of the presence and distribution of the rye and wheat repeated sequences in rye B chromosomes was carried out by fluorescent in situ hybridization. Probes used consisted of three highly repetitive sequences from rye (pSc119.2, pSc74, and pSc34) and the multigene families for the 25S–5.8S–18S and 5S rDNA from wheat (pTa71 and pTa794, respectively). pSc74 and pSc119.2 showed hybridization signals in the telomeric regions of rye B chromosomes. The remaining DNA clones did not hybridize to the B chromosomes.Key words: Secale cereale, rye, repetitive DNA, fluorescence in situ hybridizat
