The aim of research work is the identification of biochemical, molecular-biological and ecological peculiarities of plants growing on the Aral Sea dried-out bottom, and assessment of their potentials.
Scientific novelty of the research work is as follows:
220 higher plants were identified naturally occurring in the territory of the Southern Aralkum 130 of them were found for the first time; the plants widespread in the territory under study were proved to be formed on the basis of Irano-Turanian flora;
concentrations of 38 elements as constituents of plant species and of 37 elements in the soil were measured; rhenium was found in the organs of plants under study and concentrations of free amino acids as constituents of plant species widespread in the territory under study were measured; role of phenylalanine and proline in adjustment of the plants to the stress factors was proved;
total proteins and peptides were isolated from the plants widespread on the dried-out bottom of the Aral Sea were studied, their antibiotic activity to pathogens of human organism was tested;
for the first time rbcL gene of Atriplex pretovii was found to consist of 488, 537 and 811 bp; 283 and 404 bp were identified in matK gene, and 577 bp were found in psbB-psbH regions, results of sequencing were included in EMBL-EBI database;
for the first time from molecular-genetic point of view Atriplex pratovii was proved to differ from other Atriplex genus plants and Atriplex pratovii interspecific and intergeneric molecular phylogeny by rbcL and /идгК genes was developed;
plant species widespread divided into ecological groups and bioindicating properties have been established.
