FIELD: chemistry.SUBSTANCE: invention relates to field of biochemistry, in particular to genetic construction for expression of threonine-insensitive aspartate kinase in plant, where construction contains promoter, specific for phase of aging, functionally connected with coding sequence, which codes polypeptide, possessing activity threonine-insensitive aspartate kinase, and in which specific to aging promoter is selected from group, consisting of SAG12, SAG13, SAG101, SAG21 and SAG18, or their functional variants or fragments. Described are vector, plant cell, transgenic plant, material for plant reproduction, collected leaves, smoking tobacco, which contain claimed genetic construction. Also described is method of obtaining transgenic plant, which possesses ability to accumulate threonine in fading leaves in larger amount than in leaves of corresponding plant of wild type, and method of increasing the level of threonine in leaves of aging plant to the level of threonine, higher than the content of threonine in leaves of plant of wild type without impairing plant adaptation with application of said genetic construction.EFFECT: invention makes it possible to obtain transgenic plant, which possesses ability to accumulate threonine in fading leaves in larger amount than in leaves of plant of wild type.22 cl, 16 dwg, 2 tbl, 4 exИзобретение относится к области биохимии, в частности к генетической конструкции для экспрессии нечувствительной к треонину аспартаткиназы в растении, где конструкция содержит специфический для фазы старения промотор, функционально связанный с кодирующей последовательностью, которая кодирует полипептид, обладающий активностью нечувствительной к треонину аспартаткиназы, и в которой специфический к старению промотор выбран из группы, состоящей из SAG12, SAG13, SAG101, SAG21 и SAG18, или их функциональных вариантов, или фрагментов.
