耐鹽堿雅羅魚遺傳資源研究平臺簡介
耐鹽堿雅羅魚遺傳資源研究平臺致力于系統(tǒng)開發(fā)雅羅魚資源，深入探討魚類耐鹽堿的生理與分子遺傳機制，培育耐鹽堿魚類新品種，為我國水產(chǎn)科技事業(yè)發(fā)展提供科學(xué)的信息資源和技術(shù)支撐。雅羅魚具有耐鹽堿、耐低溫及種間表型差異大等特點，是開展耐鹽堿魚類良種培育和魚類耐鹽堿遺傳機制研究的模式實驗材料。
目前，該平臺搜集了分布于我國不同水域類型中具有代表性的雅羅魚野生種。我們利用這些資源已經(jīng)或即將開展下列研究：DNA分子標(biāo)記開發(fā)、野生種(群)遺傳結(jié)構(gòu)分析、遺傳連鎖圖譜構(gòu)建及QTL分析、耐堿分子遺傳機制研究和培育耐鹽堿新品種。上述研究工作的開展必將推進我國雅羅魚種質(zhì)資源深度挖掘及保護利用的進程，同時也將對魚類耐鹽堿分子機制的深入研究奠定良好的基礎(chǔ)。培育的耐鹽堿雅羅魚新品種對我國北方水產(chǎn)養(yǎng)殖結(jié)構(gòu)的調(diào)整及鹽堿水域水質(zhì)改良具有十分重要的經(jīng)濟價值和生態(tài)意義。
經(jīng)過多年努力，通過相關(guān)項目的執(zhí)行，課題組擁有一批從事鹽堿魚類基礎(chǔ)生物學(xué)、耐鹽堿分子遺傳機制、滲透壓調(diào)節(jié)生理生化分析、遺傳育種、增養(yǎng)殖研究人員在內(nèi)的人才隊伍，其中包括高級研究人員2人（研究員1人），博士3名，碩士1名，研究生11人。并與斯坦福大學(xué)、清華大學(xué)、臺灣中央研究院等國內(nèi)外院所簽訂了魚類耐堿生理生化和分子機制研究合作研究協(xié)議。課題組目前在研項目包括國家農(nóng)業(yè)行業(yè)專項等，為平臺的正常運轉(zhuǎn)和研究的順利進行提供了經(jīng)費支持。
INTRODUCTION
The platform of genetic resources for saline-alkaline resistant (SAR) Leuciscus will mainly focus on the introduction of the resources of Leuciscus distributed in China, the mechanisms of saline-alkaline resistance clarified in physiological and molecular genetic level, ,and the new varieties of SAR fish species produced through intercross or transgenosis. The representative wild species of Leuciscus distributed in different types of water environment hasve been collected, including the Leuciscus waleckii grown in Songhua River in Harbin and Dalinoer Lake in innerInner Mongolia, the L. brandti migrated from Japan Sea to Suifen River, the L. leuciscus baicalensis and L.idus grown in Erqis River in Xinjiang. The Leuciscus would be a good experimental model for studying the genetic mechanism of saline-alkaline resistance and breeding new SAR fish varieties, due to its excellent performances in high saline-alkaline and low temperature tolerance and remarkable phenotypic differences between species.
Presently, the studies have been or would be carried out as follows: 》》
