敏化突變 的英文怎麼說
中文拼音 [mǐnhuàtūbiàn]
敏化突變
英文
sensitizing mutation-
The morphological, physiological, biochemical and genetic diversities between bacillus thuringiensis wild - type strain ybt - 1463 and its plasmid - free mutant bmb171 was comparatively studied. it showed that the plasmid - free mutant strain bmb171 lost the ability to form the parasporal crystal, but there was on obvious diversities were observed on the sensitivity to 10 antibiotics, the utilization of 19 carbon sources and 12 nitrogen sources, as well as the growth properties between ybt - 1463 and bmb171, whereas the electro - transformation frequencies of bmb171 were much higher than those of ybt - 1463, respectively with 5 exogenous plasmids as the donor dnas
對出發菌株ybt - 1463和其無質粒突變株bmb171的部分形態、生理生化和遺傳學特性進行的比較研究的結果表明，突變株bmb171不形成伴胞晶體，但在個體形態與菌落特徵、對紅黴素等10種抗生素的敏感性、對葡萄糖等19種碳源和谷氨酸等12種氮源的利用能力及生長性能與出發菌株ybt - 1463無明顯差異。The antarctica plays an important role in the study of global changes and it is the only land without large - scale human activities influence which makes it is sensitive to the global climate changes. penguin is the most impartment factor in the antarctic environment and its dropping sediment records the history of the population and the distribution change on the ardley island
南極地區在研究全球變化中具有突出的地位，南極地區的各種環境因子對全球氣候變化有敏感的反應，而且它是地球上唯一未被人類活動大量影響的地區，所以，南極地區的生態學研究有特殊的重要性。Accordingly, ers2 - 1 is still able to confer ethylene insensitivity via a single receptor gene ers1 in the quadruple mutant, but at a highly reduced level compared to its function in the triple mutants. the major difference between the quadruple and triple mutants is the absence of a wild - type ers2 gene in the quadruple mutant, and we propose that the dominance conferred by ers2 - 1 can be mediated and amplified via the wild - type ers2 to the subfamily i receptor ers1
三突變體的遺傳背景與四突變體相比，只是在三突變體中保留了ers2的野生型基因，而當這個野生型的ers2基因突變后，對乙烯不敏感的ers2 - 1基因的功能便減弱了，說明顯性基因ers2 - 1在etr1 - 7 ； err2 - 3 ； ein4 - 4三突變體中的功能可以經由活化ers2后再傳給ers1 ，而不僅僅是直接傳給ers1 。Compared with the traditional technique that relies on hydrogen peroxide, jk - fast can shorten the processing period and improve the fiber quality
Taed具有低毒性，無敏感性，不會引起基因突變，降解成二氧化碳、水、氨、和硝酸鹽。Abstract : plant responses to salt stress via a complex mechanism, including sensing and transducing the stress signal, activating the transcription factors and the corresponding metabolizing genes. since the whole mechanism is still unclear, this review emphasize the biochemical events during the plant adaptation to salt stress referring to an index of importance : the homeostasis in cytoplasm, the biosynthesis of osmolytes and the transport of water. most of these biochemical events were elucidated by study of halophyte and salt - sensitive mutations, also many important genes involved were cloned and used to generate stress - tolerance phenotypes in transgenic plants. on the other hand, about the molecular mechanism in signal transduction, the research of arabidopsis mutations and yeast functional complementation provided helpful traces but not full pathway
摘要植物對鹽脅迫的耐受反應是個復雜的過程，在分子水平上它包括對外界鹽信號的感應和傳遞，特異轉錄因子的激活和下游控制生理生化應答的效應基因的表達.在生化應答中，本文著重討論負責維持和重建離子平衡的膜轉運蛋白、滲調劑的生物合成和功能及水分控制.這些生理生化應答最終使得液泡中離子濃度升高和滲調劑在胞質中積累.近年來，通過對各種鹽生植物或鹽敏感突變株的研究，闡明了許多鹽應答的離子轉運途徑、水通道和物種特異的滲調劑代謝途徑，克隆了其相關基因並能在轉基因淡水植物中產生耐鹽表型;另一方面，在擬南芥突變體及利用酵母鹽敏感突變株功能互補篩選得到一些編碼信號傳遞蛋白的基因，這些都有助於闡明植物鹽脅迫應答的分子機制。Researchers studying rat and monkey brains found that by placing the sensitive tip of an electrode near a neuron they could pick up the sudden changes in the electric field that occurred when signals coursed through the cell
研究大鼠與猴子大腦的人員發現，將電極的敏感尖端放在一神經元附近，他們能檢測到信號迅速穿過神經元時電場發生的突然變化。Such chemical sensitivity suggests to scientists that organisms may be easily affected by small but sudden changes in the chemistry of air, water, and land
這種對化學成分的敏感使科學家認識到，空氣、水體和土地中的化學成分突然的，哪怕是很小的改變，都會使生物有機體很容易受到影響。The study intends as a solution to the problem of the optimization designing of the system and the quantification inspection ubiquitously in the x - ray radiographic inspecting system, based on full comprehension and researching of high - energy x - ray digital radiography ( dr ), computerized tomography ( ct ) inspecting system, after analyzing the influence of such factors as the sensitivity of the system, the optimization designing of the radiographic inspecting system and the quantification inspection of the tiny flaw being the abrupt change structure are discussed
本論文針對x射線成像檢測系統中普遍存在的系統優化設計和定量檢測問題，在充分了解和研究高能x ?射線數字成像（ digitalradiography ，簡稱dr ） 、計算機層析成像（ computerizedtomography ，簡稱ct ）檢測系統的基礎上，通過分析影響系統靈敏度的因素，探討了射線成像檢測系統的優化設計和突變結構處微小疵病的定量檢測方法。分享友人
