The dynamics of fumarase activity in maize leaves under the conditions of different gas composition of the medium was studied. It is shown that under hypoxic conditions a decrease in this index of the enzyme under study is observed in comparison with normal conditions. It was found that in the environment of carbon dioxide and nitrogen two forms of the enzyme are observed, mitochondrial and cytoplasmic. The level of expression of fum1 and fum2 genes in green maize leaves was established in control and experimental samples. The dependence of the expression rate of fumarase genes in maize leaves is shown in different conditions of the gaseous medium.

Key words:    hypoxia, isoenzyme, regulation, fumarate hydratase, expression
