液泡膜内在蛋白(tonoplast intrinsic protein,TIP)是调控植物细胞内水分平衡的主要水通道蛋白类型,其根据进化关系可分为TIP1~TIP5等5个亚类。本研究基于前期获得的油莎豆全长转录组对1个块茎高水平表达的TIP基因(命名为CeTIP4;1)进行克隆和鉴定。序列分析显示,该基因含有2个保守的内含子,编码区全长753 bp,预测编码250个氨基酸,理论分子量为25.57 kDa、等电点(pI)为6.02、总平均疏水指数(GRAVY)为0.884,属于典型的酸性疏水型蛋白;该蛋白含有1个保守的MIP(major intrinsic protein)结构域,且具有已结晶AtTIP2;1类似的结构特征。进化分析显示,CeTIP4;1与AtTIP4;1、OsTIP4;1、OsTIP4;2和OsTIP4;3聚在一起,序列相似性为69.62%~82.94%,支持其划归为TIP4亚类。本研究在基因克隆的基础上进一步构建了其亚细胞定位载体pNC-Cam1304-CeTIP4;1。在烟草叶片中的瞬时过表达和共聚焦显微镜观察显示,CeTIP4;1定位在细胞膜。进一步的表达分析显示,CeTIP4;1具有明显的组织特异性,主要在块茎、根、匍匐茎和芽尖中表达;在起始期、膨大中期、膨大晚期和成熟期等4个典型的块茎发育时期中,CeTIP4;1基因的表达呈现先升后降的趋势,峰值出现在膨大中期,最低的是成熟期,与含水量趋势基本一致。本研究结果为深入解析油莎豆块茎的水分平衡机制奠定坚实的基础。

在晚近的国家治理中,风险规制日益成为政府工作的核心目标之一。安全保障与风险预防固然是重要的法律价值,但在公共卫生、环境等领域,行政对社会风险的过度预防,可能导致规制政策的成本收益失衡,甚至过度限制个体权利,进而影响经济社会发展。为避免行政规制落入“泛安全化陷阱”,亟需在行政规制的法律改革中引入可接受风险的理念,并将可接受风险水平作为行政规制的限度。将可接受风险理念法理化,既具有宪法根据,也有私法基础。在可接受风险理念的指引下,行政机关应当被定位为社会风险管理的辅助者,并且负有积极协助市场主体追求公共利益的职责。在制度层面落实可接受风险理念,需要在规制立法中构建风险分级分类监管制度,健全“受规制的自我规制”体系,并进一步完善风险交流制度。

油莎豆起源于非洲和地中海沿岸,是一种在块茎中高水平积累油脂的新型草本油料作物。水分平衡对于块茎的发育与代谢至关重要。液泡膜内在蛋白(TIP)是一类液泡膜定位并具有高效水分转运活性的水通道蛋白,包含TIP1~5等5个亚类。本研究基于油莎豆的基因组和转录组数据,采用RT-PCR技术对1个块茎高水平表达的TIP基因CeTIP2;1进行克隆。序列分析表明:CeTIP2;1的基因全长3323 bp,含有2个内含子,编码区长747 bp,编码248个氨基酸,理论分子量为24.73 kDa,等电点为5.09,总平均疏水指数为0.948,脂肪族指数为114.60,不稳定系数为21.76,属于稳定的酸性疏水型蛋白,与其液泡膜定位一致;该蛋白含有保守的MIP结构域,其中包括6个跨膜螺旋、2个半螺旋以及2个典型的NPA基序。CeTIP2;1与AtTIP2;1的序列相似性高达87.20%,远高于与SoPIP2;1的46.23%。进化分析进一步证实,CeTIP2;1隶属于TIP2亚类,是AtTIP2;1的直系同源基因。进化分析同时显示TIP2亚类早在单、双子叶植物分化之前就已经进化出2个小组。表达分析显示:CeTIP2;1在叶片、叶鞘、根、芽尖、匍匐茎、块茎等主要组织中均有较高水平的表达,丰度最高的是块茎和匍匐茎,最低的为芽尖;在块茎的发育过程中,呈现先升后降的钟形趋势,峰值出现在膨大中期,最低的为成熟期。此外,CeTIP2;1还在块茎的蛋白组中被检测到,表明其功能的重要性。这些结果为进一步揭示油莎豆的块茎水分平衡机制奠定坚实的基础。

质膜内在蛋白(PIP)隶属于水通道蛋白家族,其以细胞膜定位并具有高效的水分转运活性而著称。PIP高度保守,主要包含PIP1和PIP2两个亚类。天然橡胶是重要的工业原料和战略物资,其主要来源为巴西橡胶树。作为橡胶合成和储藏的特异组织,乳管与邻近的薄壁细胞之间缺乏胞间连丝,其水分平衡主要由PIP介导。通过前期研究,团队鉴定到一个PIP1亚类成员HbPIP1;4,该基因在乳管中高水平表达,然而,其在蟾蜍卵母细胞中异源表达却无水分转运活性,推测因不能有效定位到细胞膜所致。为探讨HbPIP1;4在植物体内的功能部位及作用模式,本研究构建了其亚细胞定位和双分子荧光互补(BiFC)载体。通过利用农杆菌介导法瞬时转化烟草叶片,再用激光共聚焦显微镜进行观察,发现荧光信号出现在细胞膜,这与生物信息学预测的细胞膜定位结果一致。BiFC实验进一步证实HbPIP1;4定位在细胞膜,结果同时显示,HbPIP1;4可形成同源多聚体,这与3D结构预测结果一致。上述结果为深入揭示乳管的水分平衡机制奠定了坚实的基础。但HbPIP1;4的异源互作模式还有待进一步研究。
