Therefore, the LsHNXs genes were cloned in this study, and their function was studied by RNAi. The main results were shown as follows:1 The conservative sequences of three LsHNXs genes (LsHNX1, LsHNX2, and LsHNX3), and the 3'-terminal specific sequences of LsHNX2 and LsHNX3, were cloned by RT-PCR and 3'-RACE.2 The plant RNAi vectors were constructed and the transformation of Limonium sinense was done. The RNAi lines of three single-genes and one double-gene were obtained and were propogated rapidly for the molecular and the stress tolerance analysis.3 To be compared with wild type, the Na+ and K+ contents secreted by the leaves of LsNHX1 transgenic plants were remarkably higher.

It is shown that in solution the ion pairs can exist in such different forms as contact ion pair, solvent-separated ion pair or free solvated ions. Solvent polarity influences not only the spectral properties of different forms, but the equilibrium between them as well, leading to change of physicochemical properties of the ion pairs.

观察到在溶剂中离子对可以各种形式存在，如紧密离子对、溶剂分隔离子对或溶剂化的自由离子，溶剂的极性不仅影响各种存在形式的光谱性质，而且影响它们之间的平衡关系，进而影响离子对体系的物理化学性质。
