Micron (Oxford, England : 1993), 44, 317-330 (2012-09-11)

The osmotic potential and effects of plasmolysis on photosynthetic oxygen evolution and chlorophyll fluorescence were studied in two Arctic Zygnema sp. (strain B, strain G) and two Antarctic Zygnema sp. (strain E, strain D). Antarctic strain D was newly characterized

Physiological and molecular features of Puccinellia tenuiflora tolerating salt and alkaline-salt stress.

Xia Zhang et al.

Journal of integrative plant biology, 55(3), 262-276 (2012-11-28)

Saline-alkali soil seriously threatens agriculture productivity; therefore, understanding the mechanism of plant tolerance to alkaline-salt stress has become a major challenge. Halophytic Puccinellia tenuiflora can tolerate salt and alkaline-salt stress, and is thus an ideal plant for studying this tolerance
