n.金魚草

Having two lips,as the corollas of the snapdragon. 二唇的二唇的，如金魚草的花冠。

Using genes that help color the snapdragon flower, the researchers discovered they could get the tomatoes to make anthocyanins -- turning the tomato purple in the process. 研究人員從金魚草的花朵中提取了可產(chǎn)生花青素的基因，然后將其轉(zhuǎn)移至普通西紅柿中，就培育出了紫色的番茄。
