Polymers, based on dextran and cellulose, having 2-{[(4-boronophenyl)-methyl]-ethylammonio}ethyl and -diethylammonio~ethyl groups were prepared. It was shown that these polymers could be employed for absorption of cis-diol compounds. The polymers were found to be highly specific towards polyols, carbohydrates, nucleosides, and nucleotides over a wide range of pH. The polymer based on DEAE-Sephadex A-25 was used in separating nucleosides, and in fractionating mononucleotides and carbohydrates. The chromatographic behavior of carbohydrates is defined by their structure and conformation, which are also responsible for different stabilities of the boronic complexes generated. 相似文献

The molecular organization, copy number, and chromosome location of the human TNF/LT transgenes were studied in the genomes of two transgenic mouse strains. One strain proved to carry two transgene copies arranged head-to-tail and detected on chromosome 8 by karyotyping. The other strain had one transgene copy observed on chromosome 5. The strains provide a model for studying the physiological functions of the tumor necrosis factor and lymphotoxin. 相似文献

Karyotypes of species sects. Linum and Adenolinum have been studied using C/DAPI-banding, Ag-NOR staining, FISH with 5S and
26S rDNA and RAPD analysis. C/DAPI-banding patterns enabled identification of all homologous chromosome pairs in the studied
karyotypes. The revealed high similarity between species L. grandiflorum (2n = 16) and L. decumbens by chromosome and molecular markers proved their close genome relationship and identified the chromosome number in L. decumbens as 2n = 16. The similarity found for C/DAPI-banding patterns between species with the same chromosome numbers corresponds with
the results obtained by RAPD-analysis, showing clusterization of 16-, 18- and 30-chromosome species into three separate groups.
5S rDNA and 26S rDNA were co-localized in NOR-chromosome 1 in the genomes of all species investigated. In 30-chromosome species,
there were three separate 5S rDNA sites in chromosomes 3, 8 and 13. In 16-chromosome species, a separate 5S rDNA site was
also located in chromosome 3, whereas in 18-chromosome species it was found in the long arm of NOR-chromosome 1. Thus, the
difference in localization of rDNA sites in species with 2n = 16, 2n = 30 and 2n = 18 confirms taxonomists opinion, who attributed these species to different sects. Linum and Adenolinum, respectively. The
obtained results suggest that species with 2n = 16, 2n = 18 and 2n = 30 originated from a 16-chromosome ancestor. 相似文献

We studied the influence of three derivatives of pyrido[1,2-a]benzimidazoles (PBIs), which have DNA-intercalating properties, on plant mitotic chromosome condensation, in order to increase the resolution of chromosome analysis. The efficiency of the influence of these agents was assessed using the median chromosome length on chromosome slides, as well as by the number and size of chromosome DAPI bands. We used the third chromosome of Linum grandiflorum Desf. in these experiments. The chromosome was identified on the slides using its DAPI band pattern and a molecular marker, viz., the 5S rDNA site, which is located in the proximal region of the long arm of the chromosome. The influence of the well-known 9-aminoacridine (9-AMA) DNA intercalator, which is widely used in karyotype studies of short-chromosome organisms, was used as a control in all of the experiments. It was found that the influence of each of the three PBIs in the study on the root meristem of L. grandiflorum resulted in an increase in the median length of the third chromosome, the linear centromeric DAPI band size, and the number of intercalary DAPI bands. All three PBIs acted more efficiently than 9-AMA. The median chromosome length was increased by 15?C40% and the number of intercalary bands increased by 1.5?C3 times after PBI treatment, as compared to 9-AMA treatment. At the same time, 7-CF3-PBI, in a similar manner to 9-AMA, did not change the relative size of the centromeric DAPI band, while 7-NH2-PBI and 9-NH2-7-CF3-PBI gradually increased this parameter. It is concluded that these substances can be used as intercalating agents in cytogenetic studies in order to increase the resolution of chromosome analysis. 相似文献

A new biologically active component, antibiotic eremomycin B, was isolated from the culture liquid of Amycolatopsis orientalis subsp. eremomycini, the producing strain for antibiotic eremomycin. Its structure was established by NMR spectroscopy and mass spectrometry. Eremomycin B was shown to differ from eremomycin by the presence of an N-carboxymethyl substituent in the disaccharide eremosamine fragment. 相似文献

The wide variation in chromosome number found in species of the genus Linum (2n = 16, 18, 20, 26, 28, 30, 32, 36, 42, 72, 84) indicates that chromosomal mutations have played an important role in the speciation of this taxon. To contribute to a better understanding of the genetic diversity and species relationships in this genus, comparative studies of karyotypes and genomes of species within section Syllinum Griseb. (2n = 26, 28) were carried out. Elongated with 9-aminoacridine chromosomes of 10 species of section Syllinum were investigated by C- and DAPI/С-banding, CMA and Ag-NOR-staining, FISH with probes of rDNA and of telomere repeats. RAPD analysis was also performed. All the chromosome pairs in karyotypes of the studied species were identified. Chromosome DAPI/C-banding patterns of 28-chromosomal species were highly similar. Two of the species differed from the others in chromosomal location of rDNA sites. B chromosomes were revealed in all the 28-chromosomal species. Chromosomes of Linum nodiflorum L. (2n = 26) and the 28-chromosomal species were similar in DAPI/C-banding pattern and localization of several rDNA sites, but they differed in chromosomal size and number. The karyotype of L. nodiflorum was characterized by an intercalary site of telomere repeat, one additional 26S rDNA site and also by the absence of B chromosomes. Structural similarities between different chromosome pairs in karyotypes of the studied species were found indicating their tetraploid origin. RAPD analysis did not distinguish the species except L. nodiflorum. The species of section Syllinum probably originated from a common tetraploid ancestor. The 28-chromosomal species were closely related, but L. nodiflorum diverged significantly from the rest of the species probably due to chromosomal rearrangements occurring during evolution. 相似文献
