主要內(nèi)容：山東農(nóng)業(yè)大學(xué)張憲省教授和蘇英華教授研究團(tuán)隊(duì)首次完整揭示了單個(gè)植物體細(xì)胞如何通過(guò)基因重編程“改變命運(yùn)”，最終發(fā)育為完整植株的全過(guò)程。該成果不僅破解了困擾科學(xué)界百余年的“植物細(xì)胞全能性”機(jī)制之謎，也為作物遺傳改良與高效再生提供了全新理論支撐。

研究背景
1902年，植物細(xì)胞全能性概念被提出，即植物細(xì)胞在適宜條件下可脫分化為全能干細(xì)胞，進(jìn)而發(fā)育為完整植株。然而，其分子機(jī)制始終未解，2005 年《科學(xué)》雜志將“單個(gè)體細(xì)胞如何發(fā)育成完整植株”列為最具挑戰(zhàn)的 125 個(gè)科學(xué)問(wèn)題之一。
文章概述
研究團(tuán)隊(duì)首先建立了“誘導(dǎo)單細(xì)胞起源的體細(xì)胞胚胎發(fā)生”穩(wěn)定體系，并系統(tǒng)尋找了全能干細(xì)胞的分子標(biāo)記。利用單細(xì)胞測(cè)序、活體成像等技術(shù)，首次捕捉到單個(gè)植物細(xì)胞分裂全過(guò)程。研究發(fā)現(xiàn)，轉(zhuǎn)錄因子 LEC2 與 SPCH 協(xié)同作用激活生長(zhǎng)素合成，使細(xì)胞內(nèi)生長(zhǎng)素特異性大量積累。這一過(guò)程促使原本注定發(fā)育為氣孔的前體細(xì)胞脫離氣孔發(fā)育路徑，轉(zhuǎn)化為全能干細(xì)胞，進(jìn)而啟動(dòng)胚胎發(fā)生。研究進(jìn)一步揭示，氣孔前體細(xì)胞存在一個(gè)命運(yùn)分岔點(diǎn)：細(xì)胞要么繼續(xù)分化為氣孔，要么進(jìn)入“GMC-auxin”中間態(tài)。在這一中間態(tài)下，細(xì)胞通過(guò)染色質(zhì)重塑、翻譯調(diào)控和生長(zhǎng)素信號(hào)的共同作用，激活胚胎發(fā)生程序，推動(dòng)細(xì)胞命運(yùn)從氣孔分化轉(zhuǎn)向全能干細(xì)胞，最終發(fā)育為完整植株。該研究在世界上首次全面解析了單個(gè)植物體細(xì)胞重編程形成全能干細(xì)胞并再生完整植株的分子機(jī)理，這一理論的解析不僅有助于理解植物細(xì)胞發(fā)育的根本規(guī)律，也為精準(zhǔn)調(diào)控植物再生和定向改良作物性狀提供了全新的思路與技術(shù)工具。
