Abstract
On the example of cultures of bacteria Pseudomonas sp. and Bacillus sp. the effect of humic acids in the concentration range (0-15 mg/L) on the viability of these bacteria was studied. Multidirectional effects of humic acids on microorganisms were found, namely, at concentrations of 1 and 5 mg/L, they reduce, and at 15 mg/L, they do not affect the survival of the studied cultures of bacteria. It has been established that the treatment of aqueous solutions of humic acids with a weak magnetic field affects their physicochemical properties and structural parameters, as well as enhances the biological effect in relation to different groups of microorganisms. It was established that the multidirectionality of the biological effect of humic acids on microorganisms is well explained from the position of considering humic acids as complex open non-equilibrium systems with a developed system for energy dissipation, which leads to the formation on their basis of diverse and complex self-organized structures with different physicochemical properties. The obtained concentration dependences confirm the possibility of the existence of humic acids in the studied concentration range in at least two states. Moreover, it is the state of the system (the level of self-organization), and not the relationship with the source of origin of a humic acids, mainly determines its properties. This fact determines the possibility of using the concentration of humic acids to establish the level of organization of the system, which will allow to manage the structural organization of these objects and predict their properties.

Abstract
Plant cold shock domain proteins (CSDPs) are DNA/RNA-binding proteins. CSDPs contain the conserved cold shock domain (CSD) in the N-terminal part and a varying number of the CCHC-type zinc finger (ZnF) motifs alternating with glycine-rich regions in the C-terminus. CSDPs exhibit RNA chaperone and RNA-melting activities due to their nonspecific interaction with RNA. At the same time, there are reasons to believe that CSDPs also interact with specific RNA targets. In the present study, we used three recombinant CSDPs from the saltwater cress plant (Eutrema salsugineum) - EsCSDP1, EsCSDP2, EsCSDP3 with 6, 2, and 7 ZnF motifs, respectively, and showed that their nonspecific interaction with RNA is determined by their C-terminal fragments. All three proteins exhibited high affinity to the single-stranded regions over four nucleotides long within RNA oligonucleotides. The presence of guanine in the single- or double-stranded regions was crucial for the interaction with CSDPs. Complementation test using E. coli BX04 cells lacking four cold shock protein genes (ΔcspA, ΔcspB, ΔcspE, ΔcspG) revealed that the specific binding of plant CSDPs with RNA is determined by CSD.

Abstract
A comparative study was performed to analyze the effect of cold acclimation on improving the resistance of Arabidopsis thaliana, Eutrema salsugineum and Eutrema botschantzevii plants to salt stress. Shoot FW, sodium and potassium accumulation, metabolite content, expression of proton pump genes VAB1, VAB2,VAB3, VP2, HA3 and genes encoding ion transporters SOS1, HKT1, NHX1, NHX2, NHX5 located in the plasma membrane or tonoplast were determined just after the cold treatment and the onset of the salt stress. In the same cold-acclimated E. botschantzevii plants, the Na+ concentration after salt treatment was around 80% lower than in non-acclimated plants, whereas the K+ concentration was higher. As a result of cold acclimation, the expression of, VAB3, NHX2, NHX5 genes and of SOS1, VP2, HA3 genes was strongly enhanced in E. botschantzevii and in E. salsugineum plants correspondently. None of the 10 genes analyzed showed any expression change in A. thaliana plants after cold acclimation. Altogether, the results indicate that cold-induced adaptation to subsequent salt stress exists in the extremophytes E. botschantzevii and to a lesser extend in E. salsugineum and is absent in Arabidopsis. This phenomenon may be attributed to the increased expression of ion transporter genes during cold acclimation in the Eutrema species.

Abstract
Full-length BrCSDP2 and BrCSDP4 cold shock gene sequences of Brassica rapa are obtained. It is shown that the isolated genes belong to a group AtCSP2/AtCSP4 of Arabidopsis thaliana and TsCSDP2/TsCSDP4 of Thellungiella salsuginea genes encoding proteins with a cold shock domain (CSD) and two zinc finger motives. The structure and the allelic variants of these genes are described and characterized. It is shown that the identified allelic polymorphism is due to both of point substitutions and small indels. Coefficients of total genetic similarity ranged from 1.0 to 0.53. In tern the genetic similarity coefficient for BrCSDP2 and AtCSDP2 was 0.89, and for BrCSDP4 and AtCSDP4 was 0.85.Translation in silico of gene sequences has revealed amino acid substitutions in the protein sequence, but no significant correlation between the detected polymorphism and signs of resistance to cold stress were found.

Abstract
Four genes encoding cold shock domain (CSD) proteins have been identified in salt cress [Thellungiella salsuginea (halophila), an extremophyte currently recognized as a promising model for studying stress tolerance]. The deduced proteins prove highly homologous to those of Arabidopsis thaliana (up to 95% identity) and are accordingly enumerated TsCSDP1-TsCSDP4; after the N-proximal conserved CSD, they have respectively 6, 2, 7, and 2 zinc finger motifs evenly spaced by Gly-rich stretches. Much lower similarity (approximately 45%) is observed in the regions upstream of TATA-box promoters of TsCSDP1 vs. AtCSP1, with numerous distinctions in the sets of identifiable cis-regulatory elements. Plasmid expression of sCSDP1 rescues a cold-sensitive cup-lacking mutant of Escherichia coli, confirming that the protein is functional. In leaves of salt cress plants under normal conditions, the mRNA levels for the four TsCSDPs relate as 10: 27: 1: 31. Chilling to 4 degrees C markedly alters the gene expression; the 4-day dynamics are different for all four genes and quite dissimilar from those reported for their Arabidopsis homologues under comparable conditions. Thus, the much greater cold hardiness of Thellungiella vs. Arabidopsis cannot be explained by structural distinctions of its CSDPs, but rather may be due to expedient regulation of their expression at low temperature.
