研究方向

研究方向:植物回響低溫脅迫的分子機制
作為外界主要環境因子,溫度影響植物的生長發育、植被的分布以及農作物的產量。我們實驗室主要是通過分子生物學、遺傳學和生物化學等手段,研究植物應答低溫脅迫的信號轉導途徑、低溫信號與植物激素信號之間的互動作用,以及低溫信號與生物脅迫信號之間的互動作用等。
1. 植物回響零下低溫脅迫的分子調控研究
在植物抗凍性研究方面,我們建立了穩定的凍相關突變體的篩選體系。通過該體系,我們發現蛋白激酶CRPK1(Cold-responsive protein kinase 1)參與負向調控低溫信號途徑關鍵轉錄因子CBF依賴的信號轉導。低溫激活定位於細胞膜上的CRPK1,後者磷酸化細胞質中的14-3-3蛋白,誘導其進入細胞核中,與CBF1/3蛋白互作,介導CBF1/3蛋白的泛素化降解,從而負調控植物對低溫的應答。該研究不僅揭示了低溫信號從細胞膜傳遞到細胞核中的負調控機制,也闡明了CBF蛋白翻譯後修飾的調控機制(Liu et al., 2017,Mol Cell)。而蛋白激酶OST1在植物低溫應答中發揮重要的正向調控作用。OST1激酶活性被低溫迅速誘導,激活狀態的OST1將ICE1磷酸化,抑制ICE1的泛素化降解,從而正調控植物的抗凍性(Ding et al., 2015, Dev Cell)。
在低溫信號和植物激素信號的交叉互作方面,我們發現乙烯信號通路關鍵組分均參與低溫應答。轉錄因子EIN3蛋白直接負調控低溫調節基因CBF和細胞分裂素信號負調控因子A型ARR基因的表達,從而負調控擬南芥的抗凍性。該研究明確了乙烯在植物抗低溫中的作用,同時也揭示乙烯和細胞分裂素信號之間互動作用的分子機制(Shi et al., 2012, Plant Cell)。另一個重要植物激素油菜素內酯信號通路關鍵的蛋白激酶BIN2和轉錄因子BZR1/BES1通過依賴和不依賴於CBF的方式調控下游一系列基因的表達,從而正向調節植物的抗凍能力(Li et al., 2017, Mol Plant)。利用CRISPR技術,構建了cbfs三缺失突變體,明確了CBFs在低溫馴化中的關鍵作用及CBFs的靶基因,並為低溫信號研究提供了理想的遺傳材料 (Jia et al., 2016, New Phytol)。
2. 植物回響零上低溫脅迫的分子調控研究
我們的研究發現擬南芥防衛反應中起重要作用的抗病相關基因CHS1RPP4/CHS2CHS3和LSD1/CHS4參與不同溫度下植物生長的穩態平衡調控 (Wang et al., 2013, Plant J; Wang et al., 2011, Plant J; Huang et al., 2010, Plant Physiol; Yang et al., 2010, Plant J; Huang et al., 2010,New Phytol)。研究揭示TIR-NB類蛋白CHS1通過與R蛋白SOC3互作,蛋白磷酸酶IBR5和伴侶蛋白HSP90分別與R蛋白CHS3和CHS2互作,調控R蛋白的活性,從而調控R介導的溫度依賴的細胞死亡和防衛反應 (Zhang et al., 2016, New Phytol; Liu et al., 2015, PLoS Genet; Bao et al., 2014, New Phytol)。
研究發現擬南芥磷脂結合蛋白BON1在調控溫度依賴的生長發育中是一個關鍵調控因子,BON1與兩個類受體蛋白激酶BIR1和BAK1互作,可能通過BAK1對BIR1和BON1的磷酸化,作用於同一條信號通路,協同調控溫度依賴的植物生長發育和防衛反應 (Wang et al., 2011, Plant J; Yang et al., 2007, Plant Physiol; Yang et al., 2006, Plant J; Yang and Hua, 2004, Plant Cell)。
