Bienertia sinuspersici

Bienertia sinuspersici is a flowering plant that currently is classified in the family Amaranthaceae, although it was previously considered to belong to the family Chenopodiaceae.

Bienertia sinuspersici conducts C4 photosynthesis, but lacks the two cell types, bundle sheath and mesophyll cells, that are typical of Kranz anatomy in most C4 plants. Bienertia sinuspersici and three other former chenopods (Suaeda aralocaspica, Bienertia cycloptera, and Bienertia kavirense) instead conduct single-celled C4 photosynthesis within individual chlorenchyma cells. Single-celled C4 photosynthesis is achieved in Bienertia sinuspersici by the subcellular partitioning of dimorphic chloroplasts into two distinct cellular compartments, the central chloroplast compartment (CCC) and the peripheral chloroplast compartment (PCC).
