The review highlights the basic classes of phytohormones, their localization and involvement in the regulation of sporophyte and gametophyte growth and development in pteridophytes. Gibberellins and gibberellin-like substances (antheridiogen and antheridiogen-B) involvement in the sexual polymorphism determination has been discussed. Antheridiogen that has a gibberellin skeleton in its structure is produced by a physiologically active meristem. At high antheridiogen concentrations there is formed the male gametophyte while its deficiency results in the female one. Publications dealing with studies on the content and possible involvement in the regulation of physiological processes of abscisic acid (ABA) (in regulation of spore dormancy breaking), auxins and cytokinins (in frond formation), ethylene and jasmonic acid (in resistance formation) in pteridophytes have been analyzed. A current state of research of the basic phytohormones complex components in the Polypodiophyta division is summarized in the table. [ABSTRACT FROM AUTHOR] |
