Soybean evolution from the ancient tetraploid flowers pollinate crops since the diplont, low level of genetic variation within species, genome larger and contains extensive areas of reproduction and rich repeat sequences, chromosome and small cells to carry out genetic research, which makes soybean genetic map study clearly behind other cr...

大豆是由古四倍体演变而来的二倍体自花授粉作物，种内遗传变异程度低，基因组较大并含有广泛的复制区和丰富的重复序列，染色体又很小，难于进行细胞遗传学研究，这使得大豆遗传作图研究明显落后于其它作物。

Diplotene chromosome to further reduce this time synaptonemal complex has disappeared.

双线期的染色体进一步缩短，此时联会复合体已消失。

This result suggests that genes are not disjointed entities with parts spread out from one end of a chromosome to another.

Superoxide dismutase (EC 1.15.1.1;SOD) is a metal-containing enzyme that widely exist in organisms. It catalyzes the dismutation of superoxide free radical and produces hydrogen peroxide and oxygen.It plays an important role in protecting the plasmalemma from the reactive oxygen species.A recombinant plasmid pPICZA-sodM18 was constructed and after its linearization was transferred into chromosome of Pichia pastoris GS115 by electroporation.

超氧化物歧化酶(Superoxide dismutase；EC 1.15.1.1；SOD)是广泛存在于生物体内的金属酶，是机体内唯一以超氧阴离子自由基(O_2~-)为底物的酶，它能专一地催化O_2~-的歧化反应，生成过氧化氢和氧气，能有效的抵御氧自由基和其他氧化物自由基对细胞质膜的毒性，对机体防御氧化损伤起着十分重要的作用。

In this study,we have identified C2H2 ZFP genes in the silkworm,and acquired the basic information for these genes,such as gene distribution on chromosome,gene family information and expression information.This information will be useful for further functional studies on these genes.

综上所述，本研究对家蚕基因组中的C2H2型锌指蛋白基因进行了鉴定，并通过分析获得了这些基因的基本信息，即染色体分布、基因家族信息和基因表达信息等，这些信息为进一步对家蚕C2H2型锌指蛋白基因进行功能研究打下了基础。

Barley seeds were irradiated with five different doses of 60 Co-γ ray.There were many kinds of chromosome aberration in pollen mother cells,such as bridge,laggards in anaphase I and anaphase II,asymmetrical division in anaphase I and asynchronous division in anaphase II,ring quadrivalent in metaphase I,three pole division and micro-nuclei in telophase I,micro-nuclei in tetrad and some micro-nucleus separates from the tetrad to form polyad.

大麦种子经5种不同剂量γ射线辐照后， M1植株的花粉母细胞出现多种染色体畸变类型，例如后Ⅰ、后Ⅱ中出现桥、落后，后Ⅰ中出现不对称分裂，后Ⅱ中出现不同步分裂，中期Ⅰ出现环状四价体，末期Ⅰ中有三极分裂和微核，四分体中出现微核且有的微核独立于四分体，从而形成多分体。
