lants growing in saline habitat, a tubuli-vesicular structure would occure in the mesophyll cells. The structure was composed of tubule and a layer membrane envelope and contained many tubular elements and vesicular materials which derived from the chloroplast membrane envelope, and gradually developing and complex in its structure under salt stress. This structure maybe was a kind of lysosomes could promote hydrolysis of the material in protoplasm, meanwhile, was digested by other enzymes in sap vesicle, therefore, the condensation of solute in sap vesicle could be increased, the exosmose of water could be decreased, which have some functions of proventing the cells from over-lossing water. Therefore, the structure, maybe, has important meaning for salt-resistance of plants.
