The fertility characteristics expressed during morphogenesis in first-generation self-pollinated backcrossed progenies (BC₁) obtained from amphiploid barley–wheat hybrids [Hordeum geniculatum All. (2n= 28) ×Triticum aestivum L. (2n= 42)] (2n = 70) backcrossed with common wheat were studied. It was found that, in the case of self-pollination of BC₁ plants, karyotype stabilization leads to the formation...

Russian Journal of Genetics > 2004 > 40 > 5 > 506-509

Immune lines resistant both to leaf rust and to powdery mildew were constructed on the basis of common wheat cultivar Saratovskaya 29. Synthetic wheat Triticum timopheevii/Aegilops squarrosa (AAGGDD, 2n = 42) of Savov (Bulgaria) was used as a source of resistance genes. Using cytological analysis of BC₂, we selected resistant plants (21") free from meiosis 1 (M1) defects. With these plants and...

Russian Journal of Genetics > 2004 > 40 > 5 > 500-505

The genetic expression system of generadius incompletus was studied by substituting regions of chromosome 3 from line th st ri sr ca, which has drastically reduced riexpression, to regions of chromosome 3 from a “selection” line ri s ^– having very high expression of this gene. Virtually all chromosome 3 was shown to carry polygenes controlling phenotypic expression of oligogenic mutationri. Chromosome...

Russian Journal of Genetics > 2004 > 40 > 5 > 485-490

Breeding of GC rats for the predisposition to cataleptic freezing has increased not only the frequency, intensity, and duration of freezing, but also the proportion of irritable or “nervous” rats with enhanced anxiety, defensive behavior with vocalization, jerky running, and jumpiness. An increased amplitude of the startle reflex is a correlate of this “nervousness.” The results of the comparison...

After exposure of cells of the methylotrophic yeast Hansenula polymorphaHF246leu1-1 to N-nitro-N-nitrosoguanidine, a collection of 227 mutants unable to grow on methanol at elevated temperature (45°C) was obtained. Ninety four ts mutants (35% of the total number of mutants), which were unable to grow on methanol only at 45°C but could grow at optimal temperature (37°C), were isolated. Complementation...

Genomic diversity of 21 STR loci has been studied in six ethnic populations of Daghestan (the Caucasus), namely, Avars, Dargins, Kubachians, Lezgins, Kumiks, and Nogais, and the results have been compared with these data for European, African, and East Asian ethnic groups. Daghestan is unique in its ethnic diversity, which is the greatest in the Caucasus: 26 out of approximately 50 autochthonous ethnic...

Russian Journal of Genetics > 2004 > 40 > 5 > 478-484

Collection of missense mutations in the SUP45 gene of Saccharomyces cerevisiae encoding translation termination factor eRF1 has been obtained by different approaches. It has been shown that most of isolated mutations cause amino acid substitutions in the N-terminal part of eRF1 and do not decrease the eRF1 amount. Most of mutations studied do not abolish eRF1–eRF3 interaction. The role of the N-terminal...

Russian Journal of Genetics > 2004 > 40 > 5 > 574-579

An integral model of the evolution of a Mendelian one-locus population of diploid organisms with continual allele diversity developing under density-limiting conditions or without density limitation has been proposed and analyzed. The model was used to study the mechanism of the appearance of discrete genetic structures, i.e., the fixation of a limited number of alleles. Local resistance of the resultant...

SOS-Inducible DNA Polymerases and Adaptive Mutagenesis

E. V. Babynin

Russian Journal of Genetics > 2004 > 40 > 5 > 463-471

Stability of genomes of living organisms is maintained by various mechanisms that ensure high fidelity of DNA replication. However, cells can reversibly enhance the level of replication errors in response to external factors. As mutable states are potentially involved in carcinogenesis, aging, and resistance for pathogenic agents, the existence of these states is of great importance for human health...

Analysis of the phenotypic manifestation of inactivation of several genes from the ytlI–ytnM operon containing the ribR gene and results of Northern hybridization showed that theribR gene does not have the self promoter and is transcribed from the main promoter of the ytlI–ytnM operon. Two sites of single nucleotide substitutions leading to derepression of ribR gene were identified between the putative...
