COATED VESICLES IN THE CYTOPLASM OF THE HOST CELLS IN OPHRYS LUTEA CAV. MYCORRHIZAS (ORCHIDACEAE)

Abstract

The host cells from endomycorrhizas of Ophrys lutea Cav. contain many coated vesicles associated with dictyosomes, with a membrane system (probably partially coated reticulum) and with the host's sequestration plasmalemma. The contents of coated vesicles stain with neither the PATAg test for polysaccharides nor with ruthenium red. The involvement of coated vesicles in the host/endophyte interactions during the establishment of O. lutea endomycorrhizas is discussed. Copyright © 1987, Wiley Blackwell. All rights reserved
