背景技术
在高等植物中,蔗糖是光合作用的主要产物。在由源到库的长距离运输过程中,蔗糖是作为植物体内碳水化合物运输的主要甚至是唯一的形式(Williams,L.E.,et al.,Sugar transporters in higher plants-a diversity of roles and complex regulation.Trends Plant Sci,2000,5,283-290;Sylvie L.,et al.The dual function of sugar carriers:transport and sugar sensing.Plant Cell,1999,11:707-726)。蔗糖分子进出韧皮部筛分子通过两种不同的途径进行,即共质体途径和质外体途径(Buchanan B.B.,et al.,Biochemistry and Molecular Biology of Plants.Rockville:American Society of Plant Physiologists,2000,748-776)。由于在很多种类的作物中,质外体途径占有极其重要的地位,蔗糖的跨膜运输及其在植物中的分配需要依赖于膜上的蔗糖转运蛋白进行介导,蔗糖转运蛋白作为植物所特有的一类载体蛋白,在蔗糖的分配中具有重要的生理作用,主要是在蔗糖进出韧皮部,库组织的蔗糖供给,蔗糖的贮藏,蔗糖转运调控以及其它小分子物质转运等多种生理过程中发挥重要作用(Gahrtz M.,et al.,A phloem-specific sucrose-H+symporter from Plantago major L.supports the model of apoplastic phloem loading Plant J,1994,6(5),697-706;Truernit E.,et al.,The promoter of the Arabidopsis thaliana SUC2 sucrose-H+symporter gene directs expression of β-glucuronidase to the phloem:evidence for phloem loading and unloading by SUC2.Planta,1995,196:564-570;Kühn C.,Companion cell-specific inhibition of the potato sucrose transporter SUT1.Plant Cell Environ,1996,19,1115-1123;Bürkle L.,et al.,The H+-sucrose cotransporter NtSUT1 is essential for sugar expurt from tobacco leaves.Plant Physiol,1988,118,59-68;Hackel A,et al.,Sucrose transporter LeSUT1 and LeSUT2 inhibition affects tomato fruit development in different ways.The Plant Journal,2006,45,180–192;Gabriel-Neumann E,et al.,Constitutive overexpression of the sucrose transporter SoSUT1 in potato plants increases arbuscular mycorrhiza fungal root colonization under high,but not under low,soil phosphorus availability.J Plant Physiol,2011,168(9):911-9;Siahpoosha M.R.,et al.,Modification of OsSUT1 gene expression modulates the salt response of rice Oryza sativa cv.Taipei 309.Plant Science 2011)。一些实验结果表明蔗糖转运蛋白还参与了对非生物胁迫和生物胁迫的响应(Sakr S.,et al.,Cutting,ageing and expression of plant membrane transporters.Biochim.Biophys.Acta,1997,1330:207-216;Meyer S.,AtSUC3,a gene encoding a new Arabidopsis sucrose transporter,is expressed in cells adjacent to the vascular tissue and in a carpel cell layer.Plant J,2000,24:869-882),以及蔗糖信号感应与转运效率的调控(Barker L.,et al.,SUT2,a putative sucrose sensor in sieve elements.Plant Cell,2000,12,1153-1164;Schulze W.,et al.,Function of the cytosolic N-terminus of sucrose transporter AtSUT2 in substrate affinity.FEBS Lett,2000,485:189-194;Reinders,A.,Schulze,W.,et al.,Protein–protein interactions between sucrose transporters of different affinities colocalized in the same enucleate sieve element.Plant Cell,2002,14,1567–1577)。
