Thioredoxin (TR), histone acetyltransferase (HAT), and histone deacetylase (HDAC) activities in plants of Sium latifolium and Alisma plantago-aquatica have been investigated. It is established that in the leaves of aerial-aquatic plants of S. latifolium growing in water, the TR, HAT and HDAC activities were lower than in terrestrial plants of the same species growing in the coastal zone. Relationship between the HDAC activity and reactive oxygen species (ROS) content in leaves of aerial-aquatic and terrestrial plants of A. plantago-aquatica was discovered. It is supposed that the HDAC is indirectly involved in maintaining of some pro-antioxidant level in cells to control accumulation of toxic ROS, especially under stress conditions.

Keywords: tioredoxin, histone acetyltransferase, histone deacetylase, reactive oxygen species, Sium latifolium, Alisma plantago-aquatica
