為了生存,物種均會發展出不同款式的捕獵技倆。504Please respect copyright.PENANAILvxLapfzN
這次我們將會講解經常在超級市場見到的秀珍菇,如何在大自然間捕殺獵物來獲取營養。504Please respect copyright.PENANATySZwMkwTF504Please respect copyright.PENANAPFDRJ9xpJM

(圖2)在泥土底下,蘑菇發展出名為菌絲的結構,其中之一的作用就是從泥土中吸取營養。504Please respect copyright.PENANA2B6zbcbv9w
而科學家發現,秀珍菇的菌絲還有一道獨特的地方,能夠將泥土中的桿線蟲置諸死地。504Please respect copyright.PENANAXjNEvH259n504Please respect copyright.PENANAo8U7NgSp7x

(圖3)當處於泥土的桿線蟲不慎碰到秀珍菇的菌絲之時,菌絲便會透過桿線蟲表面的絨毛觸發桿線蟲部份的神經,促使桿線蟲頭部及口腔附近的肌肉不斷抽搐,最終引發細胞啟動死亡機制逝世。504Please respect copyright.PENANANzAoMd2V89504Please respect copyright.PENANAKMmCScAMGB

逝去的桿線蟲被泥土的細菌分解後,秀珍菌便可透過菌絲吸取氮元素等物質供自己所需,這機制在土地貧瘠的區域尤其重要。504Please respect copyright.PENANAj43kPls8hw
504Please respect copyright.PENANAjsdB8ffYWQ
以這個情況來說,稱呼秀珍菌為肉食性菌類亦不之為過。504Please respect copyright.PENANANm1S9gk1fr
