THE ORIGIN OF EXINE PATTERN DIVERSITY IN ONTOGENY AND EVOLUTION


N. I. Gabarayeva, Komarov Botanical Institute, St. Petersburg, Russia


The mechanisms and ways of diversity origin of pollen wall structure have been looked through the correlation between chaos and order. The diversity of exine pattern rests on the ground of uniformity of its substructure and the variability of sporopollenin receptor distribution. The determination of pattern is carried out on molecular level, the essential part of the processes go probably by self-assembly. Different principles and modes, such as alternativity, the phenomenon of phantoms and plasmalemma movements are involved into construction of 3-D exine architectonics.
