  • 简介:氮使用效率(NUE)在中国是很低的,差不多70%应用的氮化肥的损失在high-yielding稻田被报导。以便调查高亲密关系的铵运输或举起的分子的基础进米饭(OryzasativaL.),我们分析了九铵的表示侧面transporters(AMT),OsAMT1的三各个,OsAMT2和OsAMT3,根据外部N地位在象在这些表示模式的变化一样的米饭生长的二个不同N要求阶段(年轻幼苗阶段和tillering阶段)使用即时反向的抄写聚合酶链反应(RT-PCR)。结果建议九OsAMT基因在米饭植物的不同机关被表示,包括成熟的根,新根,茎,旧叶子和新叶子并且表示模式是相应蛋白质的位置在种系发生的树上特定、独立的机关。OsAMT1;1,3;2和3;3在根和射击被表示,首先旧的叶子,OsAMT1;2和1;3主要在根,和OsAMT2;1,2;2,2;3和3;1主要在射击,首先在新叶子,并且相对更在里面茎比另外的基因。在二个不同N要求阶段的表示模式是一样;在有更大的N要求的tillering阶段,然而,OsAMTs抄本层次比在有低N要求的年轻幼苗阶段的那些大。为48h的N饥饿起来调整的OsAMT1;1,1;2,3;1,3;2,3;3并且下面调整的OsAMT1;3mRNA丰富。后面的N饥饿,NH4+和NH4NO3再供给下面调整的OsAMT1;2和3;3并且起来调整的OsAMT1;3,而NO3再供给下面调整的OsAMT1;1和1;2。这些建议OsAMT的器官特定的表示模式能被N要求和外部N地位调整。

  • 简介:中国从严肃的水问题正在经历。在在堤的构造的中国的九主要的河盆之中有许多差别,水库,制约,洪水分泌物工程,洪水转向工程,浇生态的建设,水管理管理,等等。为九条主要的河的水资源的阴影价格能提供建议给中国政府。这篇文章开发价格基于优化模型的amultiperiod输入产量接近的一个动态阴影。不同于以前的途径,新模型基于动态可计算出来的一般平衡(DCGE)解决水资源的边缘的long-termprices的问题的模型。首先,DCGE的定义和算法被详细描述。第二,为在在用国家的水管理input-holding-output的中国的1949-2050的九条主要的河的水资源的阴影价格的结果搁置因为在1999的九条主要的河被列出。这篇文章的Aconclusion是为九条主要的河的水资源的阴影价格大部分基于缺乏的程度。水资源的售价应该经由代表阴影价格的参数的用法被修订。
