易位的

Discussions are given of the fate of Ms2 during translocation in the hexoploid triticale, the exchange of the names for 4A and 4B chromosomes in common wheat and the possible expoitation of the new locus Ms2 (4BS), and the following speculations are made: In geneic genes of allopolyploid organisms the donor chromosomes tend to be intergenomically translocated to their phylogically and evolutionarily close chromosomes with the same order number and the same arm; it is cofirmed that the 7th International Conference of Wheat Genetics was right to exchange the names between chromosomes 4A and 4B of common wheat in 1988; and as a new genetic marker and a breeding tool for all the chromosome B-carrying species in the tribe of Tritceae, Ms2 (4BS) may have wide application in building and expanding the gene pool of germplasm resources of various species of wheat.

对 Ms2基因在六倍体小黑麦与原太谷核不育小麦远缘杂交中易位时的走向，普通小麦4A与4B染色体的互换更名以及 Ms2(4BS)新位点的开发利用进行了讨论：认为异源多倍体生物核基因的组间易位倾向于从供体染色体向进化亲缘关系较密切，且染色体序数与染色体臂相同的部分同源染色体易位；1988年第7届国际小麦遗传学会对普通小麦4A与4B染色体的互换更名是正确的； Ms2(4BS)作为一个新型的遗传标记，作为小麦族内所有携带B染色体组的物种的育种工具和在拓建各类小麦种质资源的基因库等方面均有广泛的用途。

One/twenty-nine chromosome robertsonian translocation was found in 4 Russion Simmental bulls, three of them were heterozygotes, one of them was homozygote.

其中3头为易位杂合体公牛，1头为易位纯合体公牛。讨论了染色体1/29易位对繁殖力的影响问题。

This review will focus on the role of GluRδ2, one of the main players in this field. Special emphasis will be placed on the processes that regulate the rapid translocation from climbing fibres to parallel fibres of GluRδ2 and the role of GluRδ2 in the reduction of supernumerary climbing fibre contacts on a single Purkinje cell.

这篇综述将集中讲这一领域中的一个主要因素GluRδ2的功能，并特别强调了GluRδ2 的上行纤维到平行纤维的快速易位的调节过程和GluRδ2 在减少过多的上行纤维与单个蒲肯野细胞接触的过程中的作用。

For different FAB subtypes,translocation was most common in M3 patients,detected in 58%;deletion was most common in M1,detected in 18%;and trisomy was most common in M5,detected in 29%.

在不同的FAB亚型中，M3患者发生染色体易位的比例最高，为58%；M1患者中发生染色体丢失的比例最高，为18%；而M5患者中发生三倍体的比例最高，为29%。

If there are two spaces between the king and the rook, then it is called "kingside castling", the common saying "short castling"; if there are three spaces between the king and the rook, then it is called "queenside castling", the common saying "long castling", As the figure shows.

如果王与车之间有两个格的称为&王翼易位&，俗称&短易位&；王与车之间有三个格的称为&后翼易位&，俗称&长易位&。如图所示

Other three alien translocation lines referring to chromosome Lr.14 of L.racemosus were also induced via irradiated pollens.After irradiated by gamma raysof 1KR does,the pollens of T.aestivum-L.racemosus Lr.14 disomic addition lineswere used to pollinate wheat varieties"Yangmai No.5"and"Mianyang No.11".M1plants have pairing between wheat chromosomes and Lr.14 ofL.racemosus at PMCMI stage were self-pollinated,and the M2 seeds used to be Giemsa C-banded andfluorescence in situ hybridized.As the result,three alien translocation lines wereobtained and T12 was observed to have distal translocation chromosomes betweenLr.14S and a wheat chromosome segment(TW-Lr.14S·Lr.14L).T13 wasidentified to contain mostly-alien-translocation chromosome(TLr.14L·Lr.14S-W).T14 was proved to contain a translocation between Lr.14L and 6BS,with approximatebreakpoint at 6BS2.2 region, FL0.22 in the short arm of chromosome T6BL.6BS-Lr.14L.

用普通小麦-大赖草Lr.14二体异附加系经辐射处理过的花粉给扬麦5号和绵阳11号授粉，M1代植株进行PMC MI染色体配对分析和Giemsa C-分带，选出PMCMI小麦和大赖草染色体发生配对的植株进行自交，M2代经RTC M期染色体C-分带和原位杂交，鉴定出3个小麦-大赖草易位系，其中T12为由Lr.14大部分和一个小麦染色体片段组成的易位染色体(TLr.14L·Lr.14S-W)；T13含由Lr.14染色体绝大部分与小麦染色体的一个小片段组成的易位染色体(TLr.14L·Lr.14S-W)；T14易位系的染色体易位发生在小麦6BS2.2区和大赖草Lr.14L之间，易位断点在T6BL·6BS-Lr.14L易位染色体的FL0.22附近。

The results indicated that an improved 1BL/1RS translocation has Glu-B3 and Yr9 without secalin,and has higher SDS-sedmentation value than common 1BL/1RS translocation.

结果表明，在87份材料中鉴定出了一种新的改良1BL/1RS易位系，该类易位系的特征是：含有来自1RS的抗条锈病基因Yr9、不含黑麦碱、具有Glu-B3基因、比一般1BL/1RS易位系具有明显偏高的SDS-沉降值。

Many of the translocation lines can'tset seed normally,some even lost the translocating chromosomes in the subsequentprogeny.

因此，在涉及Lr2、Lr7的大量易位系中，相当部分易位不能正常结实，有些易位染色体在传递过程中丢失。

The technique of CC can be used to study chromosomal changes of lung cancer, but the success rate in identifying clonal abnormal karyotypes is not high, due to the low mitotic activity, poor quality of chromosomes and the complicated karyotypic abnormalities.

特别是二例均有3号与17号染色体的易位，以及涉及13号染色体的易位(l号与13号或12号与13号易位)，这些易位是CC未曾发现的。

Many childhood leukemias result from mutations called translocations, where gene pieces on chromosomes accidentally relocate and misalign. In infant leukemia, the chromosome containing the MLL gene breaks within MLL and ends up fused to a different gene.

很多儿童白血病是由一种被称为易位的基因突变（染色体上基因片断突然移位重排）引起的，在幼儿白血病中，含有MLL的染色体破损，然后融合到其它基因上。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
