As an adaptive consequence, plants growing in saline habitats have developed various salt tolerant mechanisms such as ion selectivity through the membrane system and intracellular ion compartmentation, anatomical modifications such as salt gland on their leaves and special transfer cells for ion transport. Puccinellia. tenuiflora is prevalent in the saline swamps of northern China where soil is essentially composed of sodium carbonate, sodium sulphate or sodium chloride. P. tenuiflora grows well in these ar...
