个人简介:

刘洁,女,博士,太阳集团7237网站教师。20079月-20106月,河北农业大学太阳集团7237网站作物遗传育种专业攻读农学硕士学位,从事棉花氮素循环与体细胞胚胎发生相关性的研究;20109月-20122月,四川农业大学小麦研究所作物遗传育种专业攻读农学博士学位,从事小麦穗发芽相关基因SNP分析研究;20122-20166月,中国教育部-澳大利亚塔斯马尼亚大学公派博士,博士期间主要就读于澳大利亚联邦科工组织(CSIRO),从事水稻ALMT基因功能研究。

迄今为止,提出OsALMT4介导的苹果酸分泌影响了水稻体内锰元素分布的概念;明确了对OsALMT4表达量的调控会影响水稻植株对光线的适应性;将ALMT基因家族在生物界中的分布拓宽到细菌、真菌、苔藓等物种中。以第一作者、共同作者在《Plant Physiology》、《Frontiers in Plant Science》、《Agronomy》等国内外学术刊物上发表学术论文7篇,其中SCI收录论文5篇。

 

Personal Introduction:

Liu Jie, female, Ph.D., is a teacher of College of Agronomy, Sichuan Agricultural University. I studied at Agriculture University of Hebei for the master’s degree of Crop Breeding from September 2007 to June 2010. During this period, I mainly focused on the research of the relationship between cotton Nitrogen circulation and somatic embryogenesis. After then, I started to work on SNP analysis of wheat pre-harvest sprouting related genes at Triticeae Research Institution, Sichuan Agricultural University. From February 2012 to June 2016, I registered at University of Tasmania, Australia as a Ph.D. student, but my research of functional analysis of rice ALMT genes was mainly performed at Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia.      

So far, I have proposed the concept of the malate efflux via OsALMT4 affects Manganese distribution in rice, clarified that altered expression of the malate-permeable anion channel OsALMT4 reduces the growth of rice under low radiance, and expanded the distribution of ALMT gene family members from plant to bacteria, fungi and moss. Up to now, I have published 7 academic papers as first author or co-author on academic journals of Plant Physiology, Frontiers in Plant Science and Agronomy, 5 of which have been recorded by SCI.

 

主要研究方向:

  1. 水稻ALMT基因家族功能分析:通过水稻OsALMT4转运体功能分析相关工作,研究结果表明OsALMT4介导的苹果酸分泌显著影响了锰元素在超表达植株体内的分布,并且OsALMT4的超表达还显著影响了水稻植株对光线的适应性。

  2. 棉花体细胞胚胎发生与氮素循环的关系:氮素循环相关基因在胚性愈伤组织和胚状体中的表达量要明显高于非胚性愈伤组织,但在胚性愈伤组织和胚状体中的表达量差异不大,且再生能力强的品种酶活性高于再生能力弱的品种。

  3. 大麦新耐铝位点的鉴定:通过对大量大麦品种进行耐铝性分析发现了一个耐铝性中等的中国品种CXHKSL。CXHKSL并不具有典型的大麦耐铝基因HvAACT的5’端结构。但是通过对其耐铝机制的分析表明,CXHKSL也是通过根际分泌柠檬酸来对抗铝毒害。通过进一步对CXHKSL和铝敏感材料Gairdner 构成的双单倍体株系进行QTL分析发现,这一新的耐铝位点位于与HvAACT1一样的4H染色体区域。
