芒果MiZAT10A和MiZAT10B功能分析

【目的】锌指蛋白（zinc finger protein,ZFP）在植物非生物胁迫应答中起重要的作用,研究两个锌指蛋白基因MiZAT10A和MiZAT10B转入拟南芥对盐、干旱、重金属以及外源激素等非生物胁迫的应答,为抗逆育种提供理论依据。【方法】利用在线软件PLACE和MEME分别对芒果MiZAT10A和MiZAT10B进行启动子顺式作用元件以及motif预测和分析,并利用TBtools软件和‘四季蜜芒’基因注释文件（GFF文件,未公开）绘制染色体定位图;通过实时荧光定量分析MiZAT10A和MiZAT10B的组织表达模式;构建芒果MiZAT10A和MiZAT10B超量表达载体,采用农杆菌花序浸染法转化模式植物拟南芥,观察并记录转基因拟南芥开花表型以及在盐、干旱、重金属以及外源激素脱落酸和赤霉素处理下的根生长情况。【结果】启动子顺式元件分析显示,两个基因的启动子区域都有许多光响应元件、激素响应元件和非生物胁迫响应元件。表达模式分析显示,MiZAT10A与MiZAT10B在芽和花中表达水平最高。MiZAT10A和MiZAT10B分别获得了9株和14株转基因拟南芥,开花表型分析显示,Mi...     

THE FORECASTING MODEL AND ITS USE OF SCIENCE AND TECHNOLOGY DEVELOPMENT ZONES

The model for forecasting the development of the Science and Technology Development Zones(STDZ) and the High Technology Industry Developrhedt Zones (HTIDZ) is created with the help, of the forecasting theory and technology in system engineering, A scheme for handling the dynamic variables in the model is proposed. The development targets of the Chongqing Shapingba Science and Technology Development Zone in the coming six years are forecasted .by using the model. The model can be used widely to forecast the development of STDZ and HTIDZ and other similar social and economical systems.
