摘要植物對鹽脅迫的耐受反應是個復雜的過程,在分子水平上它包括對外界鹽信號的感應和傳遞,特異轉錄因子的激活和下游控制生理生化應答的效應基因的表達.在生化應答中,本文著重討論負責維持和重建離子平衡的膜轉運蛋白、滲調劑的生物合成和功能及水分控制.這些生理生化應答最終使得液泡中離子濃度升高和滲調劑在胞質中積累.近年來,通過對各種鹽生植物或鹽敏感突變株的研究,闡明了許多鹽應答的離子轉運途徑、水通道和物種特異的滲調劑代謝途徑,克隆了其相關基因並能在轉基因淡水植物中產生耐鹽表型;另一方面,在擬南芥突變體及利用酵母鹽敏感突變株功能互補篩選得到一些編碼信號傳遞蛋白的基因,這些都有助於闡明植物鹽脅迫應答的分子機制。In this study, it has been put forward that taking reactive nanometer magnetic fe304 particles as magnetic nucleus, and the copolymer of styrene ( st ) ? crylic acid ( aa ) as macromolecular shell, we could synthesize, magnetic polymer composite microspheres containing carboxyl groups on their surface, then microspheres are activated by thionylchloride, the surface of such magnetic composite microspheres thus produced had reactive acid chloride groups which then react with the free amino groups of the free soluble enzymes to give peptide bonds ( ? o ? h ?,
