李　霞，博士、研究員，博士生導(dǎo)師 1985-1995年在河北師范大學(xué)生物系獲得理學(xué)學(xué)士和植物生理學(xué)碩士學(xué)位，并留校任講師。1995-2001在美國Purdue University生物系和園藝系工作和學(xué)習(xí)，獲得博士學(xué)位。2001-2004年在美國Vector Tobacco公司任科學(xué)家和課題組長。2004年入選中國科學(xué)院“百人計劃”，回遺傳與發(fā)育生物學(xué)研究所石家莊農(nóng)業(yè)資源研究中心工作。 研究方向 1、植物抗逆分子機(jī)制的研究 植物對逆境響應(yīng)以及抗逆的分子機(jī)制是一個重要的生物學(xué)問題，涉及到植物在逆境下的可塑性發(fā)育、基礎(chǔ)代謝以及植物細(xì)胞、組織和個體得能量、水分、離子、氧化還原物的穩(wěn)態(tài)的調(diào)控等生物學(xué)過程。本課題組的研究方向是高等植物逆境生理和分子遺傳學(xué)。主要包括模式植物擬南芥、小麥和大豆在非生物逆境尤其抗鹽堿、干旱和低溫條件下的生理和遺傳機(jī)理。重點(diǎn)是植物根系發(fā)育對逆境適應(yīng)和調(diào)控分子網(wǎng)絡(luò)，逆境條件下植物防御代謝的轉(zhuǎn)換的機(jī)制，以及植物生理節(jié)水的遺傳學(xué)基礎(chǔ)。最終目標(biāo)是揭示植物抗逆的分子機(jī)理，用遺傳轉(zhuǎn)化手段創(chuàng)建抗鹽堿和抗旱節(jié)水新作物品系。 2、大豆固氮效率調(diào)控機(jī)理的研究 大豆是重要的經(jīng)濟(jì)作物，是植物蛋白和油脂的主要來源。大豆可以和根瘤菌共生形成根瘤，進(jìn)而把空氣中的N2轉(zhuǎn)化為植物可以利用的NH3。大豆根瘤的發(fā)育和固氮效率的高低是影響大豆高產(chǎn)優(yōu)質(zhì)的關(guān)鍵因素，二者對環(huán)境脅迫非常的敏感。本課題組利用反向遺傳學(xué)以及轉(zhuǎn)基因等方法對大豆根瘤發(fā)育和固氮效率對非生物脅迫響應(yīng)的分子機(jī)制進(jìn)行系統(tǒng)性研究。重點(diǎn)研究大豆miRNA及靶基因影響大豆根瘤發(fā)育和固氮效率的分子調(diào)控網(wǎng)絡(luò)。 發(fā)表文章（* 通訊作者） Wang Y, Li K, Chen L, Zou Y, Liu H, Tian Y, Li D, Wang R, Zhao F, Ferguson B, Gresshoff P, Li X*.
