煙草鉀離子通道研究進(jìn)展

Research Advances in Tobacco Potassium Ion Channel

摘要: K⁺通道是煙草吸收K⁺的重要途徑之一,。近年來(lái),，已從多種植物或同種植物的不同組織器官中分離到多種K⁺通道基因。筆者從K⁺通道基因類(lèi)型,、K⁺通道基因的克隆與功能,、K⁺吸收機(jī)制和K⁺通道分子調(diào)控技術(shù)等方面綜述了煙草K⁺通道研究現(xiàn)狀與進(jìn)展。對(duì)應(yīng)用生物工程技術(shù)改良煙草的鉀營(yíng)養(yǎng)性狀進(jìn)行了討論,，并對(duì)利用現(xiàn)代生物技術(shù)手段提高煙葉含鉀量進(jìn)行了展望,。

Abstract: K⁺ channel is one of the important pathway for tobacco absorbing K⁺. In recent years, Many K⁺ channel genes have been cloned from various plants or different organization of same plant. In this paper, the type of K⁺ channel gene, cloning and function of K⁺ channel, K⁺ absorption mechanism and molecular regulation technology of K⁺ channel are summarized. Applying biotechnology to improve tobacco potassium nutrition character is discussed, and utilizing the modern biotechniques to improve the potassium content of tobacco leaves is proposed.
