The use of the primary structure of the ITS1-ITS2 region for species identification in some submerged aquatic macrophytes of the genus Stuckenia.

Applicability of ITS1-ITS2 primary structure for species attribution of representatives of the genus Stuckenia was experimentally tested. Analysis of the ITS1-ITS2 region sequences of S. vaginata and S.

Identification of the gene coding for seed cotyledon albumin SCA in the pea (Pisum L.) genome.

Albumins SCA and SAA are short, highly hydrophilic proteins accumulated in large quantities in the cotyledons and seed axes, respectively, of a dry pea (Pisum sativum L.) seed. SCA was earlier shown to have two allelic variants differing in mobility in polyacrylamide gel electrophoresis in acid medium.

Discordant evolution of organellar genomes in peas (Pisum L.).

Plastids and mitochondria have their own small genomes, which do not undergo meiotic recombination and may have evolutionary fates different from each other and that of the nuclear genome. For the first time, we sequenced mitochondrial genomes of pea (Pisum L.) from 42 accessions mostly representing diverse wild germplasm from throughout the wild pea geographical range.

Identification of genome compositions in allopolyploid species of the genus Elymus (Poaceae: Triticeae) in the Asian part of Russia by CAPS analysis.

The genus Elymus L., together with wheat, rye, and barley, belongs to the tribe Triticeae. Apart from its economic value, this tribe is characterized by abundance of polyploid taxa formed in the course of remote hybridization.

Wild pea (Pisum sativum L. subsp. elatius (Bieb.) Aschers. et Graebn. s.l.) at the periphery of its range: Zagros Mountains.

Characteristics of wild peas and their habitats at the periphery of the range are interesting with respect to their potential importance for pre-breeding programs aimed at selection for different environmental conditions. However, wild pea diversity in peripheral regions is insufficiently represented in the existing germplasm collections. In such regions, wild pea populations are rare, small in size and suffer from climatic change and land exploitation, hence their focused search is strongly desirable.

Cryptic divergences in the genus Pisum L. (peas), as revealed by phylogenetic analysis of plastid genomes.

Organellar genomes may shed light on complicated patterns of plant evolution at inter- and intraspecies level. Primary structure of plastid genomes sequenced in this study and taken from public databases was characterised and compared in 22 diverse, mostly wild representatives of the genus Pisum (peas). Phylogenetic trees reconstructed via Bayesian approach on the basis of entire plastid genomes resembled those reconstructed on the basis of a nuclear gene His5 coding for a minor histone H1 subtype.

Nuclear-cytoplasmic conflict in pea (Pisum sativum L.) is associated with nuclear and plastidic candidate genes encoding acetyl-CoA carboxylase subunits.

In crosses of wild and cultivated peas (Pisum sativum L.), nuclear-cytoplasmic incompatibility frequently occurs manifested as decreased pollen fertility, male gametophyte lethality, sporophyte lethality. High-throughput sequencing of plastid genomes of one cultivated and four wild pea accessions differing in cross-compatibility was performed.

[Comparative sequence analysis of the LEA gene fragment in Pinus sibirica du tour and Pinus pumila (Pallas) regel].

A comparative sequence analysis of the LEA (Late Embryogenesis Abundant (LEA)-like gene) intron fragment was performed in Pinus sibirica and P. pumila differing in geographic origin. It was demonstrated that in P.

[Genetic study of a new color of the beet Beta vulgaris L].

A new genetic character of the beet Beta vulgaris L., named stem color, was described and studied genetically. This character was shown to be dominant trait and monogenically inherited.

[dw2, a new mutation of beet Beta vulgaris L].

Twelve dwarf plants were found in the second hybrid generation of beet. The average height of mutant plants was 21.8 cm, their leaf blades and flowers were significantly smaller than normal, and the plants exhibited male and female sterility.

Expression of mitochondrial genes in fertile and sterile sugar beet cytoplasms with different nuclear fertility restorer genes.

Variations in mitochondrial genome organization and in its expression between fertile, sterile sugar beet lines and fertile nuclear-restored plants were studied. Southern blot hybridization with COXI, COXII, COB and atpA mitochondrial genes as probes showed that changes in the mitochondrial genome organization of sterile lines are associated with variations in the location of COB, atpA and COXII, but not COXI. When the COXII and atpA genes were used as hybridization probes, differences in the primary structure of mitochondrial DNAs from sterile lines of different origin were revealed.

[Preservation of thiamine, riboflavin, niacin and ascorbic acid in vitamin-enriched minced meat products after different types of heat processing].

Enrichment of meat chopped products with thiamin, riboflavin, niacin and ascorbic acid in a dose of 1, 1.25, 10 an 75 mg (respectively) per portion provides their content in prepared products comprising a half of the daily requirements of a human in these vitamins. Different types of heat treatment (routine frying, IR- and UHF-heating) lead to relatively high preservation of the vitamins added (70-90%).
