【摘要】

：

研究了圆斑星鲽卵巢年周期发育的组织学规律及其数量形态特征变化。结果表明：圆斑星鲽产卵属一年一次分批产卵类型，卵巢发育属非同步分批成熟类型。性成熟亲鱼在年周期发育中经历5个发育时期，同时可见5个发育时相的卵母细胞，不同发育时期的卵巢中卵母细胞类型和组成比例不同。性腺指数(GSI)、肝脏指数(HSI)和肥满度(CF)在亲鱼的年周期发育中呈现规律性的变化，与卵巢发育呈现密切的关联。亲鱼卵巢发育的有效积温

GmZFP和GmTIP协同调控大豆耐非生物胁迫的分子机理研究

锌指蛋白和水通道蛋白基因是植物应答逆境胁迫的重要基因,我们从大豆中克隆了一个带有锌指结构蛋白的基因GmZFP和一个水通道蛋白基因GmTIP,发现它们受非生物胁迫诱导,对GmZFP和GmTIP蛋白的研究表明它们都主要定位于细胞膜上,而且二者是互作的；在逆境条件下,GmZFP可能充当转录因子直接结合到GmTIP启动子部位抑制其表达来共同调节植物对外界胁迫的耐性；抑制GmZFP和过表达GmTIP的组合植
