研究领域/research interest

植物分子遗传与进化、特殊油料植物储存油脂生物合成的分子机理与遗传育种。

长期目标:  通过研究植物储存油脂生物合成的遗传与分子机理, 调查关键功能基因的作用机制,发展重要性状的分子标记、构建重要农艺性状的QTL图谱, 发掘、利用植物油脂累积过程中关键基因资源为农业生产服务。

近期目标:集中研究特种油料植物蓖麻、小桐子、南美油藤累积储存油脂的遗传规律,克隆、鉴定与油含量或特殊脂肪酸(如蓖麻油酸、亚麻油酸)相关的关键靶基因的功能;同时发展以SSR和SNP为基础的分子标记,构建蓖麻含油量、种子大小等重要农艺性状的QTL图谱。

Our research interest focuses on addressing the genetic or molecular basis for biosynthesis of plant storage lipids in developing seeds. Using biodiesel plants castor bean (Ricinous communis) and physic nut (jatropha curcas) as model systems, we clone and characterize key genes in lipid biosynthesis, which are critical in controlling oil content or fatty acid compounds in developing seeds. We try to address the molecular mechanism of key lipid genes from cDNA, transcription factor, miRNA, imprinted gene, protein enzyme and environmental factors. Also, we develop SSR, SNP markers and DNA sequence to investigate the genetic diversity and relationships among germplasms, facilitating QTL mapping of interesting traits and molcecular breeding in biodiesel plants.
