mutant phenotype 中文意思是什麼
mutant phenotype
解釋
突變表型-

Rlean meat percentage is one of the most important economic traints in pig breeding programs. myostatin is a negative regulator of skeletal muscle growth. null or low activity of myostatin, individual muscle of mutant amimals would show a large and widespread increase in skeletal mass. myostatin null animals have significantly larger diameter or more quantity of fiber skeletal muscle. the phenotype was termed double muscling. in order to probe the relation between myostatin and high lean meat rate and plump - hipped trait, we sythesized the c ' 80 amino acids coding sequence of porcine myostatin and costructed the cloning and expressing vector of it
肌生成抑制素（ myostatin ，即mstn ）是近幾年來（ mcpherrona . c等， 1997 ）發現的骨骼肌生長的負調控因子，它主要在骨骼肌中表達。其活性的喪失，會引起動物肌肉的過度發育，肌纖維直徑變大或肌纖維數增加，表現為雙肌癥狀。肌生成抑制素研究的突破將對豬、肉雞、肉牛等畜禽生產性能的提高具有特別重要的意義。 -
These candidates affecting heart mutant phenotype are to be identified

The future characterization and genetic analysis for candidate mutant were carried out and find that some candidate mutant ( such as roi30 doil - 1 doi0311131 ) have good phenotype by drought h2o2 aba - stressed treatment. at the same time we also observe the development of candidate mutant at different growth stages carefully. many modal difference between mutant an d wild type at the same period were found, such as more rosette layering fatty and big in leaves, advancment or delay for the flower period, rosettes living in the main stem, shorten in figure, the amount of seed little, sterilization etc. these physiological and modal changes may reflect with maladjustment in expressions of some gene and confusion on their inner control, . we will futher study concrete and detailed function mechanism
我們對這些擬南芥侯選突變體進行進一步的鑒定和遺傳學分析，發現ro口口、 doil 、 doi口jlll3i等潛在突變株對aba 、過氧化氫及早脅迫有明顯表型，同時對潛在突變體的生長發育進行了詳細的觀察，發現多數潛在突變株與同條件下野生型比出現了許多明顯的形態改變，如:蓮座基葉增多、分層、肥大，花期提前或延遲，主莖生輪座，株型矮化，產籽量少，不育，敗育等，這些生理和形態上的差異很可能反映了它們內部某些基因的表達受到了影響、代謝調控發生了紊亂，具體和詳細的作用機制還需要進一步的研究。 -

敲除突變株的構建及其表型的改變 -
Fig. 1 the pga22 phenotype. the pga22 mutant seedlings were grown in the absence ( far left ) or presence of increasing concentrations of estradiol ( second from the left to far right )
在逐漸增加雌激素誘導劑濃度后（從左側第二株至第六株） ，突變表型逐漸增強。 -
Using conjunction mobilization, we screened the mutant of eaggec 17 - 2 with the mutant phenotype by one step. compared mutant and eaggec 17 - 2, the experiments such as growth under iron - deficient conditions, virulence testing to the mouse, and ybt biosynthesis and regulation showed that ybtp, ybtq and ybtx genes have no significant effects on iron uptake, mouse virulen
Eaggec17毛攜帶的hpi毒力島的功能研究eaggec172的ybtp 、 ybtqyybtx突變株沒有表現出鐵缺陷培養條件下的生長抑製表型，對ybt的合成無明顯影響；對野生株與ybtp突變株的鼠毒力對比實驗表明， lds 。 -
By analyzing the wing phenotype, cuticle phenotype of germline clone embryo, deficiency kit mapping, direct sequencing and searching the genome sequence database, three genes : sll, oxt and pygo were identified ( each gene corresponding to one group of mutant alleles )
並通過綜合分析翅的形態，生殖系克隆胚胎的表皮形態，以及缺失作圖，直接測序和搜索基因組數據庫，鑒定出了三個基因，這三個基因分別對應于該三類突變體等位基因。 -
The chimeric gene was transformed into rice calli by particle bombardment. many resistance calli were obtained, and gus activity was detected. in order to confirm the causality of the mutant phenotype and osdd2 gene, we took an approach of functional knockout ofosdd2 gene, with the method rnai ( rna interference )
為了進一步驗證本基因的功能，利用獲得的包含wrky保守域的cdna片斷構建了可能產生rna干涉（ rnainterference ， rnai ）的載體，利用農桿菌轉化法轉化水稻，目前已經獲得一批轉基因苗。 -
Lividans mutant strains la1 and la2 generated by gene replacement in dndb and dndc were obtained respectively. both of these two mutants lost dnd phenotype because of disruption of a respective dnd gene
首先利用基因置換實驗獲得分別在dndb 、 dndc基因內部發生基因中斷的突變菌株la1利la2 ，並通過southern雜交進行了驗證。 -
Recently, research on the sos3 / athktl double mutants in arabidopsis showed functional disruption of athktl was shown to suppress t he salt sensitive phenotype of sos3 mutant indicating that wild - type sos3 may inhibit the activity of athktl as a na + influx transporter. but hitherto there is no evidences in electrophysiology about regulation of k + and na + influx by sos3 protein
結果暗示athkt1可能是一個na ~ +內流轉運體並起了調節k ~ + 、 na ~ +吸收系統的作用，並且野生型sos3蛋白可能抑制athkt1蛋白na ~ +內流轉運體的活性， athkt1可能是sos途徑的調節對象之一。
