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。The hydrology system have some characters of complicated open macro system to a certain extent, the complexity and indeterminacy of the hydrology system becomes more and more standing out with the hydrology scale changing from the microscopical to the midscopical, even to the macroscopical, which present spatial variability, differ between the unit and the system, the model re - parameterization and the different scale model coupling

而在高拷貝質粒上的dnd基因似乎是李愛英變鉛青鏈黴菌dna異常修飾系統的分子生物學研究能表達的，因為它能紅補分別在dn劇、 dndb和咖jc發生單個基因突變的菌株，而且這種表達似乎也不會影響野生型菌株1326中原有的dnd基因簇的表達。S. lividans mutant strains zx1 ( dnd cluster deleted ) and zx64 ( dnda disrupted ) had pleiotropic mutations including low mel expression and poor sporulation. it was speculated that dnda together with its downstream dna ( 2. 5kb ) might be involved in these two phenotypes because dnda together with its downstream dna could restore normal sporulation and mel expression to zx64, while dndb and dndc had no such effect because lai and la2 showed no obvious difference in these two phenotypes from wild type s. lividans 1326
另外通過比較這幾個突變株及野生型菌株在產孢和黑色素基因（ mel ）表達方面的差異，推測dnda及其下游區域與變鉛青鏈黴菌的產孢和刺激外源黑色素基因的表達有關，而dndb和dndc則與之無關，因為la1和la2在這兩種表型上與野生型菌株無明顯差異。Whereas 65 percent of new neurons in wild mice ended up in the olfactory bulb, little more than 9 percent of the mutants ' neurons were able to complete the journey
