科普專欄–薯不揀單 - 深入淺出–不會變啡的白蘑菇

上集提及了白蘑菇表面的啡點是由Brown Blotch Disease而起，今集將會講及白蘑菇因為氧化作用而變成啡色的過程。589Please respect copyright.ＰＥＮＡＮＡz9KkSCphgF

（圖3）正常情況下，名為PPO的酵素將會處於名為Plastid的位置內，與蘑菇裡頭的Phenolic Substrate天隔一方，河水不犯井水。589Please respect copyright.ＰＥＮＡＮＡPCMtFkctJq

（圖4）而在物理性的撞擊或其他作用底下，Plastid結構被受破壞，PPO酵素便與蘑菇裡頭的Phenolic Substrate接觸，透過氧氣的協助下產生一系列的化學反應，最終形成啡黑色物質Melanin，導致白蘑菇變成啡蘑菇。589Please respect copyright.ＰＥＮＡＮＡAbltfg2QYf

（圖5）白蘑菇因氧化作用而變成啡色並不會讓蘑菇變成不得食用。589Please respect copyright.ＰＥＮＡＮＡFytRP0MdFG
移居到美國賓夕法尼亞州立大學的中國科學家Yinong Yang已成功使用CRISPR基因編輯技術將蘑菇的PPO基因剔走，製作不會變啡的白蘑菇，主要為作美觀用途。589Please respect copyright.ＰＥＮＡＮＡO38hazqtkU

只要得到法律的允許，這些不會變啡的白蘑菇便能進入商業市場。589Please respect copyright.ＰＥＮＡＮＡgi3zg7ouSs

類近的基因改造產品，已投身市場標榜不會變啡的蘋果Acratic Apple，原理同樣亦是針對PPO基因而成，但箇中並沒有用上CRISPR手段。589Please respect copyright.ＰＥＮＡＮＡ6kCQWEysij
