isolation gene 中文意思是什麼
isolation gene
解釋
隔離基因-
Cryptic species have been found in a wide range of marine organisms ; with majority of them are benthic invertebrates. in contrast, marine holoplanktons are thought to have lower diversity and slow speciation due to their strong dispersal potential. this paper reviewed studies on cryptic species and speciation in marine holoplankton. based on findings in 38 studied taxa, it was concluded that : 1 ) cryptic species are pervasive in marine holoplankton, suggesting holoplankton speciation was more active than previously thought ; 2 ) current morphospecies diversity is untenable to reflect true species diversity in marine holoplankton ; 3 ) geographic isolation may facilitate cryptic speciation of marine holoplankton. however, contribution of allopatric speciation is still questionable ; 4 ) ecological speciation may be the prevailing speciation mode in marine holoplankton. cryptic speciation in marine holoplankton is paradoxical, because rapid speciation under strong gene flow is countertuitive. solution of this paradox will help us gain deep insights of marine speciation and biodivesity
隱種廣泛存在於各類海洋生物中，尤其是底棲無脊椎動物.然而，海洋終生浮游生物由於具有較強的擴散能力，往往被視為生物多樣性低、物種形成慢.本文就海洋終生浮游生物隱種與物種形成的研究作一綜述.基於研究的38個種類，結果表明: 1 ）海洋終生浮游生物普遍存在隱種，其物種形成要比想象得快; 2 ）由於引種的廣泛存在，形態種生物多樣性無法反映海洋終生浮游生物真正的物種多樣性; 3 ）地理隔離有助於海洋終生浮游生物隱種的形成，但異域物種形成的作用仍值得商榷; 4 ）生態物種形成很可能是海洋終生浮游生物物種形成的主流模式.海洋終生浮游生物強基因流下快速的物種形成有悖于生物進化常理，解決該悖論將有助於我們對海洋物種形成和生物多樣性的理解 -

By means of plant genetic engineering, foreign insects resistance gene can be transferred into plant cell. we cloned the cpti gene and transferred it into mustard by agrobacterium - mtdi & ted transformation method. and obtained the transgenic mustard plants. the main results are as follows : 1. isolation of cpti gene total rna was isolated from cowpea seedss cotyledons and leaves. the cpti gene fragment was amplified by rt - pcr using sequences of its two sides as primers
本實驗是利用植物基因工程獲得抗蟲的轉基因芥菜植株，結果如下： 1豇豆胰蛋白酶抑制劑基因的分離分別提取豇豆種子、子葉及葉片的總rna ，逆轉錄成cdna 。以豇豆胰蛋白酶抑制劑基因兩端的序列為引物，用rt - pcr的熱啟動方法從上述cdna中擴增出目的基因片斷。 -
This paper focused on two aspects : the physiological effects of cold stress on the euonymus japonicus " zhuzi " ; the isolation of cold - induced cdna gene. the results obtained were as follows : first, the chlorophyll ( chi ) and carotenoid ( car ) contents in euonymus japonicus " zhuzi " seedlings decreased greatly as the cold stress proceeded, accompanied by the sharply increasing contents of mda and pmp. it shows that chi and car degradation under cold stress was correlated with the damage of the plasma membrane
主要研究結果如下： （ 1 ） 『粗枝』大葉黃楊在低溫脅迫下，隨脅迫時間的延長，葉片中脂質過氧化物的終產物（ mda ）含量明顯增加，細胞質膜相對透性（ pmp ）明顯增大；葉綠素（ chl ） 、類胡蘿卜素（ car ）含量降低，且其含量的降低與mda含量增加及pmp升高間呈顯著負相關，說明低溫脅迫下『粗枝』大葉黃楊幼苗chl和car的降低與生物膜的損傷有關。 -

Based on these results, the strategies for conservation e. mollis population to prevent the isolation and fragment of the populations and maintain the high genetic variation among the populations. moreover, it should be avoid the decline of gene flow was resulted from the isolation of the populations so that resulted in the differentiation and genetic decline of the population. finally, it should be adopt some method to spread continuous distribution and extend genetic diversity of the population
針對翅果油樹的遺傳結構和遺傳多樣性的研究結果，提出了保護翅果油樹種群的策略：維持現有翅果油樹種群高的種內遺傳變異水平，遏制由於人為原因而導致的翅果油樹種群隔離或片段化的趨勢，防止由於種群隔離造成基因流降低，從而引起種群分化和種群的遺傳衰退，並採取適當措施擴大種群的連續性和種群內的遺傳多樣性水平。 -
