dry air drives overlooked changes plants use water
2020/6/5
Plants take up much of the water that falls to Earth. They use what they need before releasing it through tiny holes on the surfaces of their leaves, just as people release water vapor every time they...

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...
