科普專欄–薯不揀單 - 深入淺出–陽光及水深對海洋生物基因構造的影響

海洋可分為Photic Zone(透光帶)及Aphotic Zone(無光帶)兩大區域。527Please respect copyright.ＰＥＮＡＮＡBvVHcZC75b

透光帶泛指陽光能滲進的領域，生物可有效進行光合作用。527Please respect copyright.ＰＥＮＡＮＡYMUGJv94m8
而無光帶如字面所示，為陽光無法抵達的領域，光合作用難以進行。527Please respect copyright.ＰＥＮＡＮＡVo6Iq3ht2o

（圖2）透光帶的生物能夠進行光合作用的關係，二氧化碳能有效轉化成為碳水化合物，使透光帶成為豐富碳物質的環境。527Please respect copyright.ＰＥＮＡＮＡZMZM7e6Tew

而基於死去的生物會沉積海底關係，深水領域無光帶的細菌會將生物的蛋白質消化成為氮化物，使無光帶成為豐富氮物質的環境。527Please respect copyright.ＰＥＮＡＮＡiBlrgTgDDW

有趣的是，位於多碳少氮透光帶的生物，基因排序會導致傾向製造碳需求較高的氨基酸，而非氮元素較高的氨基酸。527Please respect copyright.ＰＥＮＡＮＡwkdAK1lR5E

情況反之亦然出現在無光帶的生裡頭。527Please respect copyright.ＰＥＮＡＮＡudWhZsHuPu

這不禁引伸出一道疑問，在生物演化的過程中，外來環境所提供的營養是否會對基因排序的轉變上扮演著一定的角色。527Please respect copyright.ＰＥＮＡＮＡKYuJ5Z4Fby
