植物雖無法躲避昆蟲的侵襲,但也並非是任蟲魚肉的存在。392Please respect copyright.PENANAcdfBWbzeHZ392Please respect copyright.PENANAx0ch9sFjfh

它們對抗外敵的其中一道方式,就是在葉子中製造一些對昆蟲有毒的化學物。392Please respect copyright.PENANAlTlxwsP3PA
如果對方膽敢吃掉自己的話,下場就只有死路一條。392Please respect copyright.PENANAtbTd0Hc7Ej

(圖2)圖中紅色結構的是葉子其中一種專用作對付昆蟲的有毒化學物(對人類及大部份動物無害),而植物自身攜帶著一隻名為BtPMaT1的蛋白酶,它能夠將有毒的化學物改造成為無害化學物,相信是為了避免對付害蟲的時候會不慎毒害自己而設。392Please respect copyright.PENANATR1C73liXw392Please respect copyright.PENANA5G8YAT7hpt

換句話說,植物有著製作毒藥能力的同時,亦可製作相應的解藥自保。392Please respect copyright.PENANAldKkRiWWdE

(圖3)然而,害蟲可不是吃素的(雖然的確是在吃素),有科學家發現有部份害蟲身上竟然發展出跟植物一模一樣的BtPMaT1基因,相信是透過進食葉子時從中將該基因鑴在自己的基因圖譜裡頭,從而發展出對抗有毒化學物的方法。392Please respect copyright.PENANAJLB71DEnRO392Please respect copyright.PENANAGJ6RwuYILN

現在有不少科學家正在研究箇中的機制,若然能成功拆解箇中的秘密,分分中可以反其道而行,將只對害蟲有毒的基因注入在植物裡頭,讓害蟲們偷取後自取滅亡。392Please respect copyright.PENANAHR88jhUDJH
