This paper reviews the research progress in the area of molecular biology of magnetotactic bacteria , and it focuses on genomes and genetic system of magnetotactic bacteria , genes and protein associating with magnetosomes 本文對趨磁細菌及其胞內產物磁小體作了介紹,論述了該領域分子生物學方面的研究進展,包括與磁小體相關的基因和蛋白的研究、趨磁細菌遺傳體系及基因組方面的研究等,展望了該領域今后的發展前景。

Another possible explanation for rococo genetic systems is atavism , in which some biological mechanisms revert back to an ancestral state , although presumably with modification , in a new , derived genetic background 有關舊式遺傳學系統的另一個可能的解釋是隔代遺傳,在此過程中一些生物學機制恢復到一種原始生物才有的狀態,盡管該狀態可能會在一種新的衍生遺傳學背景下發生改變。

For instance , one correspondent concurred “ that evolution is right ? but still i see god in the will and cunning intention in the genetic system of all living organisms and in the system and order present in the laws of nature 舉例來說,一位讀者同意演化是對的,但是在所有生物的遺傳系統與自然律呈現的系統與秩序中,我仍然看見上帝的意志與巧妙的意旨。

Owing to the cofinement of the host of agrobactrium tumefliens and the difficulties of the maize inbred lines for obtaining embryogenic calli , the genetic system of maize was n ' t ideal enough 由于農桿菌介導玉米遺傳轉化受到農桿菌宿主的限制和玉米自交系獲得再生植株難的影響,使玉米自交系遺傳轉化體系仍不完善。

Two magnetosome deletion mutants were constructed by conjugative transposon mutagensis and the application of this genetic system . the two magnetosome deletion mutants were named as nm4 and nm21 respectively 并利用此體系,通過接合轉座誘變技術,獲得了2個磁小體缺失突變株: nm4 、 nm21 。

Some of these events may appear to recapitulate features of primitive genomes , providing indirect clues as to how early genetic systems could have functioned 隔代遺傳中的一些事件可能會再次反映出原始基因組的特征,從而為早期遺傳學系統是如何擁有功能提供間接的線索。

The deposits are related to each other , forming a genetic system from late paleozoic to early mesozoic eras in zhenan - xunyang area 它們構成鎮安旬陽地區晚古生代到早中生代的一個互有聯系的成因體系。

Because their parents ' genetic systems are now incompatible , hybrid offspring either do not survive or are sterile 因為父母的遺傳系統已互不相容,混血子女不是活不了就是不育。

The result of such combined effects of the genetic system and the environment is strong homozygosity of the biotypes found by the author . 遺傳系統和環境的這種聯合效應的結果,使作者看到了生物型的強純合性。
