中國(guó)科學(xué)院華南植物園農(nóng)業(yè)生物技術(shù)研究中心在線發(fā)表《A simple and efficient in planta transformation method based on the active regeneration capacity of plants》,文獻(xiàn)中使用了LUYOR-3415RG便攜式雙波長(zhǎng)熒光蛋白激發(fā)光源用于綠色熒光蛋白GFP的表達(dá)。
植物遺傳轉(zhuǎn)化技術(shù)是植物基因工程和現(xiàn)代農(nóng)業(yè)分子育種的必要工具。然而,現(xiàn)有的植物遺傳轉(zhuǎn)化方案復(fù)雜且效率較低,制約了多數(shù)資源植物或農(nóng)作物的遺傳改造,已成為植物資源開(kāi)發(fā)和利用的技術(shù)障礙。因此,開(kāi)發(fā)高效且多應(yīng)用的植物遺傳轉(zhuǎn)化技術(shù)已成為植物或農(nóng)業(yè)科研領(lǐng)域的重要研究方向。研究人員經(jīng)過(guò)多年探索和研究,成功建立了一種以植物主動(dòng)再生能力為基礎(chǔ)的新型植物遺傳轉(zhuǎn)化方法(Regenerative Activity-dependent in Planta Injection Delivery,RAPID)。該研究利用強(qiáng)再生能力植物甘薯,進(jìn)行多種遞送方式測(cè)試,發(fā)現(xiàn)通過(guò)甘薯莖段注射遞送方法能快速獲得陽(yáng)性器官和轉(zhuǎn)化個(gè)體,同時(shí)在農(nóng)桿菌菌種、侵染濃度、化學(xué)活性劑等方法條件上對(duì)轉(zhuǎn)化效率進(jìn)行優(yōu)化提升,并完成了多種報(bào)告基因和遺傳編輯工具的應(yīng)用,隨后通過(guò)遺傳學(xué)和細(xì)胞學(xué)分析方法確認(rèn)了植物分生組織高效轉(zhuǎn)染以及新生轉(zhuǎn)化器官個(gè)體的快速再生,是迅速高效地獲得穩(wěn)定轉(zhuǎn)基因植株的根本原因。目前,RAPID方法已成功應(yīng)用于甘薯、馬鈴薯、厚藤等無(wú)性繁殖的經(jīng)濟(jì)作物或資源植物。
與傳統(tǒng)遺傳轉(zhuǎn)化方法相比,RAPID方法具有較高的轉(zhuǎn)化效率(提高20至100倍),操作流程更為簡(jiǎn)便(縮短2至3倍),且無(wú)需昂貴且復(fù)雜的組織培養(yǎng)過(guò)程。RAPID方法克服了傳統(tǒng)方法在快速遺傳轉(zhuǎn)化方面的局限性,打破了各類資源植物開(kāi)發(fā)和利用的瓶頸?;谥参镏鲃?dòng)再生能力及無(wú)性繁殖的特點(diǎn),此方法有望應(yīng)用于更廣泛的植物物種,實(shí)現(xiàn)更多特色資源植物和經(jīng)濟(jì)作物的性狀改良與種質(zhì)創(chuàng)新,以推動(dòng)相關(guān)領(lǐng)域的基礎(chǔ)研究和應(yīng)用研究發(fā)展,為特色植物的高效遺傳改良和現(xiàn)代農(nóng)業(yè)育種應(yīng)用提供理論和方法支撐。
文獻(xiàn)摘要:
Fluorescence detection
Fluorescence of the mScarlet reporter in live transgenic tissues was observed under a fluorescence stereo microscope (M205 FA, Leica, Germany) with a red fluorescence filter (Exc 540–580 nm, Em 593–667 nm). The spontaneous fluorescence spectra of sweet potato were observed under a confocal microscope (SP8 STED 3X, Leica, Germany). One-week-old adventitious roots were freshly selected for testing of root samples, and the third mature leaf of nascent shoots was selected for testing of leaf samples. Transgenic sweet potato materials containing the GFP reporter were observed using a dual-wavelength fluorescent protein excitation light source (Exc 440 nm, Em 500 nm, 3415RG, LUYOR, China). The regions near the phloem at the base of the stems were peeled to reduce epidermal autofluorescence, and the whole plant was irradiated with a light source under dark conditions. Green fluorescence was detected in the inner regions of the stems of positively transformed plants.
