To get more factors associated with erythropoiesis in K562 cells, modified differential display reverse transcription polymerase chain reaction method was applied to identify genes with differential expression in uninduced and hemin-induced K562 cells. Remarkable differential ESTs were firstly selected for cloning, sequencing and analyzed with bioinformatics methods.

为了进一步获得分化过程中相关基因表达的信息，我们应用改良的差异显示RT-PCR技术，分析K562细胞在Hemin诱导的红系分化前后的基因表达变化，获得红系分化相关基因的线索，进而确定在红系分化中起重要作用的基因，并研究它们的作用机制。

The research on the Na+/H+ antiporter gene from Zostera marina L. can help to find the structural and functional difference of the different plant Na+/H+ antiporter gene and help to mastering the salt-tolerance mechanisms of the Na+/H+ antiporter gene.

研究大叶藻中Na~+/H~+逆向转运蛋白基因对于了解不同植物Na~+/H~+逆向转运蛋白基因在结构与功能上的差异，以及进一步深入了解该类基因的耐盐作用机理具有重要意义。

The wheat transformation frequency was between 0.33~0.66%, and cultivated time was only about 3~4 months.4 Through the hybridization of Anhui local wheat cultivated variety and the herbicide resistance variety which is including Bar gene by genetic engineering, the herbicide resistance F1 generation plant were obtained which was self-crossed or backcrossed with Anhui variety.

转化周期为3~4个月左右。4 杂交育种以含Bar基因的抗除草剂小麦基因遗传工程体为基因供体，与安徽品种进杂交，获得的F1后代均为抗性植株。

Six plants of BC2F1 pyramiding Xa23 and IPT genes were further obtained in the combinations of "[(9311/// He'xi 15/CBB23//GC-1) 9311] 9311","[(E32/// He'xi 15/CBB23//GC-1) E32] E32". After backcrossed and self-crossed 1~2nd, the plants pyramiding Xa23 and IPT genes can be used in program of hybrid rice breeding.

携带IPT基因的抗病植株再与杂交稻亲本进行回交，在2个BC2回交组合&[（9311///合系15/CBB23//GC-1） 9311] 9311&和&[（E32///合系15/CBB23//GC-1） E32] E32&中获得了7株携带IPT基因与Xa23基因的植株，这些植株再经过1~2代回交和自交，即可用于杂交稻育种。

GUS staining shows that GUS gene was expressed in stems, leaves, calyxes, stamens and siliques in transgenic Arabidopsis plants, with higher expression in green tissue such as stems, leaves, siliques, while invisible in roots, petals, and seeds. The data indicate that MPBQ MT gene promoter was likely to be expressed preferentially in green tissues such as stems, leaves, and young siliques.

GUS组织化学染色结果表明，在MPBQ MT启动子驱动下，报告基因GUS在拟南芥的茎、叶、花萼、雄蕊、种荚均有表达，且在茎、叶、种荚中表达量较高，而在根、花瓣和种子中则没有观察到GUS基因的表达，表明MPBQ MT基因可能仅在拟南芥幼嫩茎、叶、种荚等绿色组织中特异性高表达。

Part of one gene could be recombined with part of other gene to give one normal gene.

The RT-PCR method can extract the intrahepatic bile duct cancer cell′s hTR gene.We construct the eukaryon express vector containing the antisense RNA and hammerhead ribozyme gene successfully.

RT-PCR法可调出其hTR基因有效片段；成功构建了针对hTR模板区的反义RNA基因和核酶基因的真核表达载体。

It contains 215 bp, named as ZM908. Biosoftware anlysis sug gests that ZM908 gene properly belongs to the mRNA-like non-coding RNA gene which is purposed to lack of obvious open reading frame (the longest possibly contains 98 AA), contain poly tale and have stable RNA structure in vivo. ZM908 contains high conserved nucleotide sequence with ZM401 (including 371-598bp, 698-847bp and 929-1047bp in ZM908). The highest conserved sequence reaches 86%.The RT-PCR analysis result revealed that ZM908 is transcriptable.

基因分析显示这段序列含1215bp，命名为ZM908；采用生物学软件对ZM908序列和结构进行分析，表明该基因缺乏明显的开放阅读框架，序列中最长可能的开放阅读框架仅编码98个氨基酸，具有poly尾部结构，RNA分子具有稳定的二级结构，符合非编码RNA基因的特点，可能属于类似于mRNA的非编码基因；ZM908与ZM401有高度保守的区段(ZM908序列中有三段和ZM401是高度保守的，分别为371-598bp，698-847bp和929-1047bp)，相似性最高达到86%。
