細胞分裂素 (cytokinin,CTK)從玉米或其他植物中分離或人工合成的植物激素。一般在植物根部產(chǎn)生,是一類促進胞質(zhì)分裂的物質(zhì),促進多種組織的分化和生長。與植物生長素有協(xié)同作用。是調(diào)節(jié)植物細胞生長和發(fā)育的植物激素。在細胞分裂中起活化作用,也包含在細胞生長和分化及其他相關(guān)的生理活動過程中,如激動素(KT)、玉米素(ZT)、6-芐基氨基嘌呤(6-BA)等。
合成部位:根尖、葉、芽
同位素標記法
同位素標記法,是借助同位素原子以研究有機反應歷程的方法。
放射性同位素示蹤法能準確定量地測定代謝物質(zhì)的轉(zhuǎn)移和轉(zhuǎn)變,與某些形態(tài)學技術(shù)相結(jié)合(如病理組織切片技術(shù),電子顯微鏡技術(shù)等),可以確定放射性示蹤劑在組織器官中的定量分布,并且對組織器官的定位準確度可達細胞水平、亞細胞水平乃至分子水平。
符合生理條件
在放射性同位素實驗中,所引用的放射性標記化合物的化學量是極微量的,它對體內(nèi)原有的相應物質(zhì)的重量改變是微不足道的,體內(nèi)生理過程仍保持正常的平衡狀態(tài),獲得的分析結(jié)果符合生理條件,更能反映客觀存在的事物本質(zhì)。 放射性同位素示蹤法的優(yōu)點如上所述,但也存在一些缺陷,如從事放射性同位素工作的人員要受一定的專門訓練,要具備相應的安全防護措施和條件,在日前個別元素(如氧、氮等)還沒有合適的放射性同位素等等。在作示蹤實驗時,還必須注意到示蹤劑的同位素效應和放射效應問題。所謂同位素效應是指放射性同位素(或是穩(wěn)定性同位素)與相應的普通元素之間存在著化學性質(zhì)上的微小差異所引起的個別性質(zhì)上的明顯區(qū)別,對于輕元素而言,同位素效應比較嚴重。因為同位素之間的質(zhì)量判別是倍增的,如 3H 質(zhì)量是 1H 的三倍,2H 是 1H 的兩倍,當用氚水(3H2O)作示蹤劑時,它在普通 H2O 中的含量不能過大,否則會使水的物理常數(shù)、對細胞膜的滲透及細胞質(zhì)粘性等都會發(fā)生改變。但在一般的示蹤實驗中,由同位素效應引起的誤差,常在實驗誤差內(nèi),可忽略不計。放射性同位素釋放的射線利于追蹤測量,但射線對生物體的作用達到一定劑量時,會改變機體的生理狀態(tài),這就是放射性同位素的輻射效應,因此放射性同位素的用量應小于安全劑量,嚴格控制在生物機體所能允許的范圍之內(nèi),以免實驗對象受輻射損傷,而得錯誤的結(jié)果。
