ABSTRACT
Four isoforms of H+-ATPase of plasma membrane MHA1, MHA2, MHA3, MHA4 are expressed in the corn seedling roots with prevalence of genes MHA3 Ñ MHA4. The exposure of seedlings in the presence of 0.1 M NaCl activated the expression of MHA4 gene isoform, that demonstrates its important role in the processes of adaptation to salinization conditions. In vacuolar membrane, where potential is created by two Ð+-pumps, sodium ions activated gene expression of only Ð+-ÐТРase of V-type, taking no effect on the expression of Ð+-pyrophosphatase. The seeds pretreatment by synthetic preparations Methyure and Ivine did not affect gene expression of Ð+-pumps. Thus we can suppose that the ability of the above preparations to activate functioning of Ð+-pumps in the presence of sodium ions is realized at the post-tranlation level.
