Description
Technical field
The present invention relates to a kind of translocator and encoding gene and application in the plant genetic engineering field, particularly relate to the Na of salicornia europaeal
+/ H
+Its encoding gene of Reverse transship albumens And and application.
Background technology
Salt damage is the serious limiting factor of crop yield.Understand the anti-salt mechanism of plant, clone's salt resistant gene is also transferred in the salt-sensitive farm crop, cultivates the genetically modified crops new variety of anti-salt, for the China that more than 500,000,000 mu of salt wasteland is arranged, has crucial meaning.
Plant has formed a series of adaptation mechanism in order to resist salt stress, mainly be by micromolecular non-toxic organic solute of accumulation and ion in tenuigenin, and separating realizes osmotic equilibrium in vacuole.The higher plant cell vacuole accounts for 95% of complete expansion cell cumulative volume, Na for plant
+Be the cell needed basic nutrition composition of growing, Na
+Separating be the necessary guarantee that it is survived in salt environment.Na
+/ H
+Reverse transport protein (antiporter) is a kind of Na
+The antiport body, distribution is all arranged, the Na on the vacuole skin on cytoplasmic membrane and vacuole skin
+/ H
+Antiporter is with the Na in the tenuigenin
+Against Na
+Concentration gradient is transported in the vacuole separating and concentrates, the Na on the cytoplasmic membrane
+/ H
+Antiporter is with the Na in the tenuigenin
+The reverse outer high Na of born of the same parents that is transported to
+In the environment, thereby reduced the murder by poisoning of organoid in the sodium ion pair cell matter, the osmotic equilibrium of keeping cell has been played an important role.
Na in the plant
+/ H
+Antiporter finds it is on the barley plasma membrane the earliest, and after this research report is all arranged on plasma membrane and vacuole skin, finds Na in a large amount of halophytess and non-halophytes up till now
+/ H
+The antiporter vigor.Separated Na from Arabidopis thaliana (AtNHX1), paddy rice (OsNHX1), northern saltbush (AgNHX1), ice leaf Herba Portulacae Grandiflorae (McNHX1)
+/ H
+The antiporter gene proves that this expression of gene product has Na
+/ H
+The function of exchange.Though these genes overwhelming majority is isolating from the glycophyte with low reverse transportation vigor, former study shows that halophytes generally has in vacuole efficiently separating Na
+Mechanism.
Salt tolerance belongs to complex character, and this viewpoint is also supported in the existence of a large amount of salt stress reacting phase correlation genes.Term single gene generally can not significantly improve the salt tolerant level of crop, needs the synergy plant of a plurality of resistant gene of salt just to have high-salt tolerance.Yet the Arabidopis thaliana plant that changes the AtNhx1 gene can grow by normal growth in 200mM NaCl.The AtNhx1 gene of Arabidopis thaliana is changed in the tomato over to overexpression vacuole Na
+/ H
+The transgenic Fructus Lycopersici esculenti of antiporter can normal growth under 200mM NaCl coerces, bloom and solid.Although Na in the blade
+Concentration height, but Na in the tamato fruit
+Concentration is very low.Illustrating changes Na
+/ H
+The antiporter single-gene can obviously improve plant salt endurance, simultaneously, has the specificity that organ is expressed, and has provided powerful support for Na
+/ H
+The vital role that antiporter is had aspect plant salt endurance.
Salicornia europaeal is the halophytes of in the world salt tolerant, is the most potential a kind of halophytes of developing into novel crop simultaneously, has more widely in China to distribute, and can be higher than normal growth under the condition of sea water salinity.Plant materials succulence and carnification, food can find to have very heavy saline taste, illustrate that plant materials holds salt amount height.These unusual salt-tolerant traits of salicornia europaeal show in this plant and to have Na extremely efficiently undoubtedly
+Reverse transportation and storage mechanism.
Summary of the invention
The purpose of this invention is to provide salicornia europaeal Na
+/ H
+Its encoding gene of Reverse transship albumens And.
Salicornia europaeal Na provided by the present invention
