Abstract In subfamily Salsoloideae family Chenopodiaceae most species are C 4 plants having terete leaves with Salsoloid Kranz anatomy characterized by a continuous dual chlorenchyma layer of Kranz cells KCs and mesophyll M cells, surrounding water storage and vascular tissue.

Oecologia 21 , — Journal of Ecology 45 , — Botanicheskii Zhurnal [In Russian] 71 , — An important adaptation to CO 2 -limited photosynthesis in cyanobacteria, algae and some plants was development of CO 2 -concentrating mechanisms CCM 1. Evolution of a CCM occurred many times in flowering plants, beginning at least 15—20 million years ago, in response to atmospheric CO 2 reduction, climate change, geological trends, and evolutionary diversification of species 2.
In plants, this is achieved through a biochemical inorganic carbon pump called C 4 photosynthesis, discovered 35 years ago 3. C 4 photosynthesis is advantageous when limitations on carbon acquisition are imposed by high temperature, drought and saline conditions. It has been thought that a specialized leaf anatomy, composed of two, distinctive photosynthetic cell types Kranz anatomy , is required for C 4 photosynthesis 4.
We provide evidence that C 4 photosynthesis can function within a single photosynthetic cell in terrestrial plants. Borszczowia aralocaspica Chenopodiaceae has the photosynthetic features of C 4 plants, yet lacks Kranz anatomy.
This species accomplishes C 4 photosynthesis through spatial compartmentation of photosynthetic enzymes, and by separation of two types of chloroplasts and other organelles in distinct positions within the chlorenchyma cell cytoplasm. Badger, M.
