- Title
ROLE OF GOLGI APPARATUS IN MUCILAGE PRODUCTION AND CYST FORMATION IN EUGLENA GRACILIS (EUGLENOPHYCEAE).

- Abstract
Dark grown cells of Euglena gracilis Klebs (strain Z Pringsheim) encyst when placed in minus nitrogen media for 48-72 h in the dark. The number of cisternae per dictyosome decreases from 10-20 to 6-12 during encystment. Cisternae dilate and fill with mucilage within 12-18 h after induction. The material is secreted into the reservoir and depositedonto the cell surface. The encysting cells rotate as they develop resulting in the deposition of a thick mucilaginous layer over the cell surface. The secretion product has been identified as polysaccharide with the periodic acid-silver methenamine reaction. Mucilage has not been observed in the endoplasmic reticulum adjacent to the pellicle. The product present in the dictyosomes and on the cell surface react identically to the silver reagent.
