學(xué)科組簡介?? ?? ??
本學(xué)科組是我國率先從事陸生藻類、生物土壤結(jié)皮和空間生物學(xué)研究的科研團(tuán)隊，主要以荒漠、鹽堿地、臨近空間等特殊環(huán)境中的藻類為研究對象，研究它們的多樣性、生理代謝、適應(yīng)進(jìn)化、空間生態(tài)生命支持系統(tǒng)構(gòu)建、經(jīng)濟(jì)產(chǎn)物等方面的特征及形成機(jī)理。已建立測定藻類固沙能力的標(biāo)準(zhǔn)方法，開辟利用藻類進(jìn)行退化土壤生態(tài)系統(tǒng)綜合治理的新技術(shù)；構(gòu)建的空間生命支持系統(tǒng)在近地軌道實現(xiàn)了20多天穩(wěn)定運行，并執(zhí)行了十多次的中外空間飛行計劃。目前承擔(dān)的科研任務(wù)主要有國家重點研發(fā)計劃、國際合作專項、中國科學(xué)院戰(zhàn)略性先導(dǎo)科技專項(A類)、國家載人航天工程項目、國家自然科學(xué)基金等。相關(guān)成果已獲國家授權(quán)發(fā)明專利數(shù)11項，省部級自然科學(xué)二等獎1項，科技進(jìn)步三等獎2項。發(fā)表科研論文兩百多篇(SCI源刊160多)，參編專著3部。?
研究方向有：?
1) 運用高通量測序、多組學(xué)等大數(shù)據(jù)手段，跨極干旱、干旱、半干旱到半濕潤多個氣候帶，從群落組成、裝配，藻類生長代謝、環(huán)境互作等方面研究自然生物結(jié)皮及人工誘導(dǎo)藍(lán)藻結(jié)皮的生態(tài)環(huán)境效益及作用機(jī)理，以推動接種藍(lán)藻的生態(tài)修復(fù)技術(shù)的革新。?
2) 將分子生態(tài)學(xué)實驗手段(高通量擴(kuò)增子、比較基因組和轉(zhuǎn)錄組)與生物統(tǒng)計學(xué)方法相結(jié)合，綜合評估環(huán)境脅迫條件下藍(lán)藻細(xì)胞生理、分子調(diào)控與群落多樣性及種間相作響應(yīng)網(wǎng)絡(luò), 以期深入認(rèn)識陸生藍(lán)藻多樣性及其維持生態(tài)系統(tǒng)功能的潛在機(jī)制。?
3) 從微藻的碳固定、轉(zhuǎn)化途徑、高附加值產(chǎn)物積累、碳流分配調(diào)控等層面研究微藻在減排和經(jīng)濟(jì)利用方面的潛能。?
4) 利用高通量測序、生物信息學(xué)、分子生物學(xué)等技術(shù)，研究藻類在多種脅迫(高溫、高鹽、強(qiáng)輻射等)下，信號傳導(dǎo)和表觀遺傳方面的響應(yīng)機(jī)制。?
5) 以微藻、原生動物、魚類、維管植物等構(gòu)建不同封閉系統(tǒng)，研究各成員適應(yīng)空間飛行環(huán)境的生長代謝和互作關(guān)系，及封閉系統(tǒng)的生態(tài)功能和穩(wěn)定性，以期為宇航員提供氧氣、食物等生態(tài)生保系統(tǒng)。?
