Monolignins participation in nature adaptation of Trapa natans L. to water environment

Abstract

Olena M. Nedukha

Localization and distribution of monolignins (syringyl and quaiacyl) in Trapa natans L. cell walls of epidermis, photosynthesizing parenchyma and vessels of swimming and submerged leaves at vegetative phase of growth have been investigated with laser confocal microscopy. The established differences in lignin ingredients allocation and their content are indicated on differential synthesis of syringyl and quaiacyl, that possible are connected with cell differentiation, water environment and leaf passing from water on water surface. Positive correlation between syringyl content in cell walls, the ratio of syringyl to quaiacyl (S/G) and environment of leaf growth are revealed.
