glycine betaine 中文意思是什麼
glycine betaine
解釋
甘氨酸甜菜堿-
Depending on the conserved amino acids of glycine betaine abc transporter, a pair of degenerate primers were designed
在h . trueperi發現有甘氨酸甜菜堿abc轉運系統。 -
So genes implicated in expressing glycine betaine are considered as the most important and the most promising plant salt - tolerant genes
因此甜菜堿合成酶基因被認為是最重要和最有希望的鹽脅迫抗性基因。 -
Then, a piece of degenerate primer was designed according to the conserved amino acids of glycine betaine abc transporter system glycine betaine - binding protein as a reversed primer. combined with the opuaa - up, a 2. 3 kb fragment was obtained through pcr. blast result showed a fragment which contained the partial opuaa, the whole opuab and partial opuac sequences were obtained
再次，根據甘氨酸甜菜堿atp轉運系統底物結合蛋白的氨基酸保守序列設計下游簡並引物，與atp結合蛋白的上游簡並引物組合，經pcr擴增獲得2 . 1kb的條帶，測序后通過blast比較，結果顯示獲得atp結合蛋白基因的部分序列、通透酶的全部編碼序列和部分甘氨酸甜菜堿結合蛋白基因的核苷酸序列。 -
Many diverse species of plants accumulate glycine betaine ( glybetaine ) in response to various stresses, and the biosynthesis and accumulation of glybetaine are thought to contribute to various stress
許多植物在受到各種脅迫時，都會引起甘氨酸甜菜堿的積累，甘氨酸甜菜堿的生物合成與積累是植物對脅迫的一種適應機制。 -
Depending on the degenerate primers which were designed according to the conserved amino acids of glycine betaine secondary transporter, a fragment about 1 kb was obtained by pcr. the pcr fragment was purified and labeled with dig as a probe
將其總dna用sau3ai部分酶切后，收集4 15kb大小的酶切片段，克隆到用bamhi酶切的puc18中，構建halobacillussp . d8基因組文庫，共獲得約9000個重組質粒。 -
Choline dehydrogenase ( cdh ) isolated from escherichia coli, can help the expression of glycine betaine efficiently. to get some salt - tolerant plants, the cdh gene, mediated by agrobacterium, was transformed to the haploid of populus simoniixp. nigra
本實驗以農桿菌（ agrobacteriumtumefaciens ）為介導進行遺傳轉化，將編碼cdh的耐鹽基因（ bet - a ）導入小黑楊（ populussimonii p . nigra ）單倍體植株（ haploid ）的基因組內，以期獲得耐鹽植株。 -
Halobacillus trueperi accumulates glycine betaine under condition of high osmolarity. a partial fragment of the glycine betaine transporter beth gene was obtained from the genome of h, trueperi with degenerate primers. through southern blot hybridization and inverse pcr, a 5. 1 kb ecori fragment containing the beth gene was sequenced
將擴增片段用地高辛標記成探針，與用不同限制性內切酶完全酶切的h . trueperi總dna片段作southern雜交，結果顯示在ecori酶切片段的5 . 1kb處有陽性信號。 -
Consequently, study on the mechanisms of salt - tolerance in plants and breeding of salt - tolerant plants has become a key issue in plant biology nowadays. as an important plant osmotic regulators, glycine betaine in plants, under the osmotic stress, can be accumulated in order to give the plants high salt - tolerance by reducing osmotic pressure and maintaining proteinic structure in cell
甘氨酸甜菜堿（ glycinebetaine ）是一種重要的調滲物質，在鹽脅迫下有些植物能通過體內甘氨酸甜菜堿的積累保護細胞內蛋白質的結構和功能，降低細胞水勢，從而來增加自身的耐鹽能力。
