The normal course of meiosis depends on regular pairing of homologous chromosomes. In intergeneric hybrids, including those of wheat, there is no chromosome pairing because there are no homologs. In F1 wheat/rye hybrids, pairing is largely prevented by the pairing homoeologous1 (Ph1) gene. In its presence, there are only rare instances of pairing; most(More)
Synthetic hexaploids are bridges for transferring new genes that determine resistance to stress factors from wild-type species to bread wheat. In the present work, the method of developing the spring bread wheat variety Pamyati Maystrenko and the results of its study are described. This variety was obtained using one of the immune lines produced earlier via(More)
Pathogenesis-related (PR) proteins participate in complex plant defense responses to pathogens. It is known that members of two PR-protein families (PR4 and PR10) exhibit ribonuclease activity in some cases. These proteins were found to be able to inhibit the growth of pathogenic fungi, and ribonuclease activity is necessary for the manifestation of this(More)
The states of 18S/5S mitochondrial (mt) repeat and some chloroplast (cp) DNA regions have been investigated in alloplasmic lines of common wheat carrying cytoplasm of the barley species Hordeum marinum subsp. gussoneanum Hudson and H. vulgare L. and in the progenies of the reciprocal hybrids between Triticum aestivum L. and Secale cereale L. The(More)
Protein COP1 (COnstitutive Photomorphogenesis 1) is a key regulator of plant photomorphogenesis. In darkness, COP1 affects expression of more than 20% of Arabidopsis thaliana genes; primarily, this is associated with the involvement of COP1 in proteolysis of light-controlled transcription factors; COP1 suppresses expression of photomorphogenesis genes. Some(More)
Extracellular Serratia marcescens nuclease is an extremely active enzyme which non-specifically degrades RNA and DNA. Its antiviral activity was previously shown both in animals and in plants when applied exogenously. Transgenic tobacco plants (Nicotiana tabacum L. cv. SR1) expressing S. marcescens chimeric, mutant, and intracellular mutant nuclease gene(More)
Morphological and symbiotic traits were studied in local endemic forms of the pea originating from Egypt, Syria, Afghanistan, and Palestine. A number of endemic forms exceeded the regionalized Druzhnaya cultivar of the fodder pea in productivity of the seeds in field and greenhouse experiments. In order to improve nodulation and nitrogen fixation, endemic(More)
Symbiotic traits—nodulation, nitrogen fixation, and productivity—were studied in seven introduced cultivars and three candidate lines of pea (Pisum sativum L.). The cultivars grown at two nitrogen nutrition levels differ in traits associated with nodulation and nitrogen fixation. The results can be utilized in pea breeding for nitrogen fixation.
The genetic diversity of common wheat hybrid lines Triticum aestivum/Triticum durum and Triticum aestivum/Triticum dicoccum (2n = 42, F6–7) using chromosome-specific microsatellite (SSR) markers and C-banding of chromosomes was studied. Cluster analysis of data obtained by 42 SSR markers indicated that the hybrid lines can be broken into three groups(More)
Indole-3-acetic acid (IAA) is the key plant hormone of the auxin class, which controls all processes of plant growth and development. Information on IAA biosynthesis, metabolism, and transport is of great importance for understanding nearly all morphogenetic processes in plant development. Nevertheless, our knowledge about the organization of this auxin(More)
