An electrophoretic analysis of histone H1 and its fragments was carried out for several orders of insects. A total of more than 500 histone H1 variants were examined. For some of them a study of general molecular structure was performed by the method of incomplete succinylation. The molecular length of the fragment containing the C-terminal domain(More)
An electrophoretic analysis of histone H1 of Pisum sativum L. was carried out using the collection of 883 accessions of cultivated peas originating from different regions of the Old World. The closely linked genes of five H1 subtypes (2–6) form a cluster, the gene of subtype 1 being located on another chromosome. The fast allelic variant of subtype 1 was(More)
The review sums up the long experience of the authors and other researchers in studying the genetic system of garden pea (Pisum sativum L.), which controls the development of nitrogen-fixing symbiosis and arbuscular mycorrhiza. A justified phenotypic classification of pea mutants is presented. Progress in identifying and cloning symbiotic genes is(More)
Two Fix− mutants of pea (Pisum sativum L.) which are unable to fix molecular nitrogen, E135f (sym-13) and Sprint-2Fix− (sym-31), were crossed to create the doubly homozygous recessive line, named RBT (sym-13, sym-31). The ultrastructural organization of nodules of the RBT line was compared with that of each of the two parental mutant lines and with the(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)
Chemical mutagenesis of the pea laboratory line SGE with ethyl methane sulfonate was carried out. In the analysis of 425 families (2069 plants) of the M2 generation 45 putative symbiotic mutants were selected, including 30 mutants that form ineffective nodules (the Fix− phenotype), 13 mutants that are unable to form nodules (the Nod− phenotype) and two(More)
Mycobacterium tuberculosis (Mtb) is an intracellular pathogen that mainly affects alveolar macrophages. We have still no satisfactory vaccine against tuberculosis, and more than one-third of the global population are carriers of this pathogen. For the development of a vaccine that would induce not only humoral but, particularly, cell-mediated immunity, we(More)
Sperm of freshwater bivalve mollusk Anodonta piscinalis was found to contain two fractions of lysine-rich histone: somatic histone H1 and sperm-specific protamine-like histone, named Hp. A detailed analysis of H1 and Hp structure was carried out by means of N-bromosuccinimide, chymotrypsin and pepsin cleavage followed by determination of the lysine residue(More)
Analysis of joint inheritance of symbiotic locus and 12 molecular and morphological markers of pea linkage group III was performed. The linkage between symbiotic locus sym31 and 11 analyzed markers was obtained. Using the computer programme AntMap the detailed genetic map of the region around locus sym31 was constructed and its fine position in linkage(More)
