静电纺丝技术是一种制备超细纤维的重要方法，纤维直径为微米至纳米级，电纺纤维膜比表面积大、孔隙率高、纤维直径小等优点使其在水过滤、气过滤方面拥有巨大的优势。醋酸纤维素
Engineering sex-specific sterility is critical for developing transgene-based sterile insect technology.Targeted genome engineering achieved by customized z
大豆(Glycine max)作为一种豆科植物,可以在根瘤菌侵染后形成特殊的根器官(根瘤)从而和根瘤菌形成共生的关系来固定大气中的氮气,保证大豆即使在低氮含量的土壤中也能正常生长。油菜素甾醇(brassinosteroids,BRs)作为一种类固醇激素,可以调控大豆结瘤,但是BRs对大豆结瘤的调控机制却并不清楚。本文以大豆为研究对象,通过一系列生理生化实验研究了BRs对大豆根瘤发育的调控,主要研究
