Differentiation of morpho-physiological forms of Slum latifolium L. using molecular genetic markers

L. E. Kozeko, E. L. Kordyum, V. I. Glazko

Search for possible molecular genetic markers of three natural morpho-physiological forms of S. latifolium L. (one terrestrial and two aerial-aquatic forms) was carried out with three enzymatic systems — acid phosphatase, peroxidase and esterase. The results of an isozyme analysis of leaves indicate differentiation between these forms on seven isoperoxidases and three isoesterases. Possible patterns of adaptation of the S. latifolium plants to contrast water conditions at the ontogenetic and population-genetic levels are discussed.
