Abstract
Chromosomal rearrangements that lead to recombination suppression can have a significant impact on speciation, and they are also important for breeding. The regions of recombination suppression in wheat chromosome 5B were identified based on comparisons of the 5B map of a cross between the Chinese Spring (CS) variety of hexaploid wheat and CS-5Bdic (genotype CS with 5B substituted with its homologue from tetraploid Triticum dicoccoides) with several 5B maps of tetraploid and hexaploid wheat. In total, two regions were selected in which recombination suppression occurred in cross CS × CS-5Bdic when compared with other maps: one on the short arm, 5BS_RS, limited by markers BS00009810/BS00022336, and the second on the long arm, 5BL_RS, between markers Ra_c10633_2155 and BS00087043. The regions marked as 5BS_RS and 5BL_RS, with lengths of 5 Mb and 3.6 Mb, respectively, were mined from the 5B pseudomolecule of CS and compared to the homoeologous regions (7.6 and 3.8 Mb, respectively) of the 5B pseudomolecule of Zavitan (T. dicoccoides). It was shown that, in the case of 5BS_RS, the local heterochromatin islands determined by the satellite DNA (119.2) and transposable element arrays, as well as the dissimilarity caused by large insertions/deletions (chromosome rearrangements) between 5BSs aestivum/dicoccoides, are likely the key determinants of recombination suppression in the region. Two major and two minor segments with significant loss of similarity were recognized within the 5BL_RS region. It was shown that the loss of similarity, which can lead to suppression of recombination in the 5BL_RS region, is caused by chromosomal rearrangements, driven by the activity of mobile genetic elements (both DNA transposons and long terminal repeat retrotransposons) and their divergence during evolution. It was noted that the regions marked as 5BS_RS and 5BL_RS are associated with chromosomal rearrangements identified earlier by С-banding analysis of intraspecific polymorphism of tetraploid emmer wheat. The revealed divergence in 5BS_RS and 5BL_RS may be a consequence of interspecific hybridization, plant genetic adaptation, or both.

Abstract
Мягкая пшеница (Triticum aestivum L.), сорта которой широко используются в мировом про-
изводстве зерна, плохо скрещивается с видами других родов Triticeae Dum., что ограничивает возмож-
ности введения чужеродного генетического материала в ее генофонд и создания новых сортов, хорошо
адаптированных к различным неблагоприятным абиотическим и биотическим факторам внешней среды.
Известно, что скрещиваемость мягкой пшеницы с представителями других родов контролируется генами
Kr1–Kr4 (Crossability with Rye, Hordeum and Aegilops spp.) и геном SKr (Suppressor of crossability). Из названных
генов наиболее сильное влияние на признак оказывают SKr и Kr1. В рецессивном состоянии, когда гены не
функционируют, может завязываться более 50 % зерновок от числа цветков в колосе при опылении пыль-
цой чужеродного вида. Оба гена локализованы в хромосоме 5B. Расположение гена SKr в коротком плече
хромосомы 5B ограничено маркерами GBR0233 и Xgwm234 в тесном сцеплении с маркерами Xcfb341, TGlc2
и gene12. Ген Kr1 расположен в длинном плече хромосомы 5B, проксимальнее гена Ph1, между EST-SSR-
маркерами Xw5145 и Xw9340. Маркеры, разработанные для гена SKr, применяли для контроля переноса его
рецессивного аллеля skr в другие генотипы мягкой пшеницы, что позволило получать формы с высокой за-
вязываемостью гибридных зерновок при скрещивании с рожью. Однако в целом использование маркеров
генов SKr и Kr1 в практической маркер-ориентированной селекции и молекулярном скрининге образцов
ex situ коллекций изучено недостаточно. Большие перспективы в этом плане открывает определение пол-
ной нуклеотидной последовательности гена Kr1 у контрастных по скрещиваемости сортов мягкой пшени-
цы, это дает возможность создания внутригенных аллель-специфичных маркеров. В представленном обзо-
ре рассмотрены генетические ресурсы, созданные посредством гибридизации мягкой пшеницы с рожью;
вопросы географического распространения легко скрещивающихся форм пшеницы и генетического кон-
троля совместимости пшеницы и ржи; достижения в использовании молекулярных маркеров в картирова-
нии Kr-генов и контроле их передачи.

Abstract
BACKGROUND The IWGSC strategy for construction of the reference sequence of the bread wheat genome is based on first obtaining physical maps of the individual chromosomes. Our aim is to develop and use the physical map for analysis of the organization of the short arm of wheat chromosome 5B (5BS) which bears a number of agronomically important genes, including genes conferring resistance to fungal diseases. RESULTS A physical map of the 5BS arm (290 Mbp) was constructed using restriction fingerprinting and LTC software for contig assembly of 43,776 BAC clones. The resulting physical map covered ~ 99% of the 5BS chromosome arm (111 scaffolds, N50 = 3.078 Mb). SSR, ISBP and zipper markers were employed for anchoring the BAC clones, and from these 722 novel markers were developed based on previously obtained data from partial sequencing of 5BS. The markers were mapped using a set of Chinese Spring (CS) deletion lines, and F2 and RICL populations from a cross of CS and CS-5B dicoccoides. Three approaches have been used for anchoring BAC contigs on the 5BS chromosome, including clone-by-clone screening of BACs, GenomeZipper analysis, and comparison of BAC-fingerprints with in silico fingerprinting of 5B pseudomolecules of T. dicoccoides. These approaches allowed us to reach a high level of BAC contig anchoring: 96% of 5BS BAC contigs were located on 5BS. An interesting pattern was revealed in the distribution of contigs along the chromosome. Short contigs (200-999 kb) containing markers for the regions interrupted by tandem repeats, were mainly localized to the 5BS subtelomeric block; whereas the distribution of larger 1000-3500 kb contigs along the chromosome better correlated with the distribution of the regions syntenic to rice, Brachypodium, and sorghum, as detected by the Zipper approach. CONCLUSION The high fingerprinting quality, LTC software and large number of BAC clones selected by the informative markers in screening of the 43,776 clones allowed us to significantly increase the BAC scaffold length when compared with the published physical maps for other wheat chromosomes. The genetic and bioinformatics resources developed in this study provide new possibilities for exploring chromosome organization and for breeding applications.

Abstract
Group of experiments were carried out to verify possibility of gene introgression from common wheat into Aegilops. The artificial indoor crossbreed was conducted using 7 genotypes from 4 wheat relative species as female, and common wheat as male. The experiment result shows that different species has variable cross ability. Among the 4 Aegilops species, the highest cross rate is from the combination of Aegilops tauschii × Triticum aestivum (46.49% for genotype Ae42, 22.58% for Y92), the second is from Aegilops ovata × T. aestivum (14.76% for Y100, 12.11% for Ae23), the third is from Aegilops cylindrica × T. aestivum (2.23% for Ae7, 8.50% for Y145), and the lowest is from Aegilops speltoides × T. aestivum (0.19%). Hybrid embryos from different combinations have different ability of callus initiation and germination. The hybrid embryos from A. ovata/T. aestivum and Ae. tauschii/T. aestivum have a higher level of callus initiation and germination. Ae. cylindrica/T. aestivum has a middle level, while the Ae. speltoides has a lower level. The interspecific hybrids between Aegilops and common wheat have so low fertility. In back-crosses, the seed-set rate of hybrids of Ae. ovata/T. aestivum is 3.71% and 4.36% respectively back-crossed with male and female parents, while for hybrids of Ae. cylindrica/T. aestivum, they were 0 and 0.33% respectively, and for Ae. tauschii/T. aestivum, 0.33% and 0 respectively. On selfing of the hybrids, the seed-set rate is 0 (no seed set from 9750 florets) for the combination of Ae. cylindrica/T. aestivum, 0.044% (3 selfed seeds out of 6870 florets) for Ae. ovata/T. aestivum and 0 (no seed set from 7253 florets) for Ae. tauschii/T. aestivum. The research suggests that the probability of gene introgression from T. aestivum into Aegilops species is very low in nature.

Abstract
BACKGROUND Variability of heading date may assist in wheat adaptation to local environments. Thereafter, discovery of new heading date determinants is important for cereal improvement. In this study we used common wheat cultivar Chinese Spring (CS) and the substitution line of CS with 5B chromosome from T. dicoccoides (CS-5Bdic), different in their heading date by two weeks, to detect determinants of heading date on 5B chromosome. RESULTS The possible influence of the VRN-B1 gene, the most powerful regulator of flowering, located on 5B chromosome, to differences in heading time between CS and CS-5Bdic was studied. The sequencing of this gene from CS-5Bdic showed that an insertion of a nucleotide triplet produced an additional amino acid in the corresponding protein. No changes in the transcription levels of each homoeologous VRN-1 loci were found in CS-5Bdic by comparison with CS. To ascertain the loci determining heading date difference, a set of 116 recombinant inbred 5В chromosomal lines as a result of hybridization of CS with CS-5Bdic were developed and their heading dates were estimated. Using the Illumina Infinium 15 k Wheat platform, 379 5B-specific polymorphic markers were detected and a genetic map with 82 skeletal markers was constructed. Phenotype (heading date) - genotype association analysis revealed seventy eight markers in pericentromeric region of 5B chromosome significantly associated with heading date variation. Based on this estimation and synteny with model crop genomes we identified the three best candidate genes: WRKY, ERF/AP2 and FHY3/FAR1. CONCLUSIONS We supposed that the difference in activity of WRKY, ERF/AP2 and/or FHY3/FAR1 transcription factors between CS and CS-5Bdic to be a probable reason for the observed difference in heading dates. Data obtained in this study provide a good basis for the subsequent investigation of heading time pathways in wheat.

Abstract
In wheat, exotic genotypes harbor a broad range of spike-related traits, and can be used as a source of new genes for germplasm enhancement in wheat breeding programs. In the present study, a population of 163 recombinant inbred lines was derived from a cross between an elite line (WCB414) and an exotic line (WCB617) with branched spike (supernumerary spikelet; SS) head morphology. The population was evaluated over four to six environments to identify quantitative trait loci (QTL) associated with nine spike-related traits and 10 agronomic traits. A genetic map consisting of 939 diversity arrays technology (DArT) markers was constructed. Composite interval mapping identified a total of 143 QTL located on 17 different wheat chromosomes and included 33 consistent and definitive QTL. The amount of phenotype variation explained (PVE) by individual QTL ranged from 0.61 to 91.8%. One major QTL for glume pubescence was located in a QTL-rich region on the short arm of chromosome 1A, where loci for other traits such as for kernels per spike (KS) and spike length (SL) were also identified. Similarly, a cluster of QTL associated with yield-related, agronomic and spike-related traits contributing up to 40.3% of PVE was found on the short arm of chromosome 2D, in the vicinity of a major QTL for SS-related traits. Consistent and major QTL identified in the present study may be useful in marker-assisted breeding programs to facilitate transfer of desirable alleles into other germplasm. Desirable QTL alleles were also contributed by the exotic line, suggesting the possibility of enriching the breeding germplasm with alleles from SS genotypes.
