Abstract

The endomembrane system of the adaxial epidermal cells of the membranous ligule of the grass Lolium temulentum L. has been studied by conventional transmission electron microscopy, and by using zinc iodide-osmium tetroxide impregnation with examination of thick sections at 100 kV. The components of the endomembrane system are the nuclear membranes, rough endoplasmic reticulum (present in both cisternal and tubular forms), dictyosomes, dictyosome-derived vesicles, coated vesicles, plasma membrane and tonoplast. Direct continuity between tubular endoplasmic reticulum and the cis face of dictyosomes is demonstrated and the applicability of the endomembrane concept to this putative secretory tissue is discussed. The presence of vesicle-like profiles apparently within the outer tangential walls is reported.
