Salt sac cell

Mesembryanthemum crystallinum。 It is a salt sac cell that the appearance shows like a crystal

A salt sac cell (えんのうさいぼう, epidermal bladder cell; EBC) is the epidermic cell which is special, and developed for the saline accumulation that a part of the halophyte has. I am seen in plants of Chenopodiaceae, mesembryanthemum department, the wood sorrel department.

There is a thing having the special epidermic cell which developed to isolate salts which entered the body in one of a halophyte to grow in the salts accumulation soil and the soil which is high in salts density in the soil including the neighborhood of shore. The salt sac cell is a kind of the try comb (the single cell projection body which grew on the surface of the leaf) with kind. A diameter is usually around 500μm. The feature is that have a big vacuole, and, other than water, salts, is known to store compounds such as a flavonoid or the stereotypical cyanine to the vacuole [¹]; [²] [³] [⁴].

In the case of the CAM type photosynthesis of the Mesembryanthemum crystallinum, it is known to act on a maleate storage [⁵].
