ABC transporter is one of the largest protein families which involve in maintenance of osmotic homeostasis,nutrient uptake,pathogen resistance and metal tolerance.In this study,30 ABC genes in dwarfpolish wheat were discovered,which were classified into seven subfamilies(ABCA-ABCG).Expression patterns of 13 ABC genes in roots and leaves under different metal stresses were analysed.All 13 ABC transporters were differentially regulated by various heavy metals,which indicated that these ABC transporters played diverse roles under different heavy metal stresses.For example,we inferred that TpABCA could affect the composition of fatty acid by Cu and Cd.TpABCB genes could be regulated by heavy metals through affecting auxin or malate accumulation and distribution.TpABCC might be important for transport of phytate by uptaking heavy metals.TpABCG genes could be regulated by heavy metals through transporting ABA or immediately induced by heavy metals.

经过漫长的自然和人工选择，地方小麦品种对当地的环境条件具有良好适应性.地方小麦品种是现代小麦改良的重要基因库，但是其优良的环境适应类基因与较为负面的产量、品质基因并存，导致地方小麦品种在现代育种过程中利用不充分.我国保存的小麦地方品种超过上万份，约占小麦资源保存总数的1/3.通过对1300余份中国地方小麦主要农艺性状的连续4年考察，我们筛选出723份，进行了基于DArT标记与660K小麦SNP芯片
基于国际小麦基因组测序协作组织的合作,我们构建了小麦7DL染色体物理图谱,挑选出了4457个MTP克隆,contigN50为348KB.对这些克隆采用二代测序,组装获得了1454个scaffold,最长scaffold达到2.1Mb,scaffold的N50达到391kb,N90为108kb,拼接序列总长为391Mb,覆盖了整个染色体臂的82％,基本完成了小麦7DL的序列草图.为了验证BAC组装的
小麦远缘杂交与染色体工程技术将小麦族外源物种的优异基因转移到栽培小麦中,为小麦分子育种创制了一大批可持续利用的种质资源.由于小麦族植物基因组结构的复杂性,特别是基因组中重复序列达80％以上,为准确鉴定小麦-外源渐渗系新种质带来了困难.在小麦与非洲黑麦(Secale africanum)、多年生簇毛麦(Dasypyrum breviaristatum)和茸毛偃麦草(Thinopyrum interm

AGC类蛋白激酶基因的功能研究在哺乳动物中已经取得的了长足进展,但是在小麦中却鲜有报道。小麦纹枯病主要由腐生营养型真菌禾谷丝核菌(Rhizoctonia cerealis)引起土传病害。本研究通过基因芯片分析,从抗纹枯病小麦中分离了一个受禾谷丝核菌诱导表达的DNR-类型的AGC类激酶编码基因TaAGC1,并研究了其生化特性和抗病功能。序列和系统发育分析表明,TaAGC1编码丝氨酸/苏氨酸蛋白激酶,
