It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.

M1代的生物学性状、幼苗的抗氧化酶活性、MDA含量、蛋白质含量和染色体畸变率及微核率等发生了较大的变化。2）对其矮杆变异株和紫色茎杆突变体（M2）做RAPD和AFLP分子鉴定等研究，结果显示了矮杆变异体和紫色茎杆突变体的DNA序列发生了改变，而非仅仅产生生理损伤；同一种变异体或突变体，在M2代单株间也存在着明显的差异，表明它们可能还处于分离状态。

Human beings have acquired illustrious accomplishments in many fields of natural science through millennia evolution of human civilization, but there has been many ill-defined enigmas in biology, a vital subject involved the secrets of human beings selves, in which one of the most interesting questions is that how the polymer as DNA and RNA moves in confined environments.

人类文明经过几千年的演化发展，在自然科学的诸多领域都取得了辉煌的成就，但是涉及到人类自身奥秘的学科——生物学，却有许多未解之谜，因此它也成为当今最有活力的学科之一，其中最引人注目的一个问题就是DNA，RNA等分子在细胞中的动力学行为。

This integration allows users of NCBI's Entrez databases to quickly categorize proteins, genes and small molecules by metabolic pathway, disease state or other BioSystem type, without requiring time-consuming inference of biological relationships from the literature or multiple experimental datasets.

这个整合允许NCBI的Entrez数据库的用户通过代谢通路，疾病状态或其他BioSystem类型快速的分类蛋白质，基因和小分子，不需要从文献或多个实验数据集中耗时的推论生物学关系。

To further elucidate the mechanism of BMP in regulating cell differentiation and to provide basis for BMP gene therapy, this study centers on the effects of BMP2 gene transfection on fibroblasts and contains the following works:① A 1.2kb fragment containing full length human BMP2 coding region was inserted into pBK-CMV (expressed both in protocaryon and eukaryon) by using predetermined orientation methods, resulting in phagemid expression vector for BMP2 (pBK-B2).② pBK-B2 was transfected into NIH3T3 cells by using LipofectAMINE.

为了进一步从分子水平探讨BMP对细胞分化的调控作用，并为BMP基因疗法的建立提供依据，本实验围绕BMP2基因转染对成纤维细胞的生物学作用进行了以下几个方面的工作：①将含有人BMP2全长编码序列的基因片段(1.2kb)定向克隆于噬菌粒表达载体pBK-CMV中，成功构建了人BMP2噬菌粒表达载体pBK-B2。

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%。
