基因重组让植物也能吃肉
基因重组 植物 吃肉 维纳斯捕蝇草
2020/5/18
植物是如何进化出肉食性的？在1960年上映的一部美国恐怖电影——《恐怖小店》里，只需要一滴人血。但在现实生活中，却没有这么简单。现在，一项针对三种密切相关的食肉植物的研究表明，基因的巧妙重组帮助它们进化出捕捉和消化富含蛋白质食物的能力。食肉植物已经进化出许多诱捕猎物的狡猾方法。例如，猪笼草使用富含酶的“陷阱”消化昆虫，而维纳斯捕蝇草、囊泡貉藻和匙叶茅膏菜则移动捕捉猎物。当可怜的猎物被抓住时，匙叶茅...

俄罗斯：培育出能够发光的植物
俄罗斯 发光 植物培育
2020/5/8
俄罗斯科学院生物有机化学研究所和莫斯科大学生物系的科研人员利用基因移植法，将发光蘑菇的几个基因转移到烟草的DNA中，首次培育出在夜间可以发光的植物。有关专家指出，未来发光植物可用来装饰房屋和公共场所，因此该项科研成果具有很好的商业用途。莫斯科大学生物学植物园经理弗拉基米尔·丘布教授称，多年来，科研人员一直试图从萤火虫、细菌中移植发光基因来培育发光植物，但一直未取得成功。而俄罗斯科研人员2年前研究蘑...

俄罗斯采用SCT方法开展植物组织再生研究
俄罗斯 SCT方法 植物组织再生
2020/2/10
来自俄科学院西伯利亚分院网站的报道，该分院细胞和遗传所采用SCT（single cell transcriptomics，单细胞转录组学）方法开展植物组织再生的单细胞研究，此项研究结果表明除干细胞外，遭受伤害区域附近的其他类型细胞的非对称（再生）分裂也参与再生过程，细胞层面上对植物再生过程的认知，对制定农作物个性化损伤修复策略具有非常重要的意义。相关成果发布在《西伯利亚科学报》上。
