為了生存，物種均會發展出不同款式的捕獵技倆。644Please respect copyright.ＰＥＮＡＮＡ6pYy1zlh5K
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。644Please respect copyright.ＰＥＮＡＮＡmqIwgEJeu1

(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。644Please respect copyright.ＰＥＮＡＮＡ6lVhYpjxKk
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。644Please respect copyright.ＰＥＮＡＮＡK2alYX2eJB

(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。644Please respect copyright.ＰＥＮＡＮＡMN2bM7F6UQ

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。644Please respect copyright.ＰＥＮＡＮＡuwmcUgwbt9

以這個情況來說，稱呼秀珍菌為肉食性菌類亦不之為過。644Please respect copyright.ＰＥＮＡＮＡnLh4rSJLNp
