phytoene 中文意思是什麼
phytoene
解釋
八氫番茄紅素-
The coding region of the cdna of the phytoene desaturase gene was cloned by pcr and inserted into vector pbi121 containing intron - kanamycin
再生苗經過戍r和pcrs 。 : : hernbl 。 t分子檢測證明獲得了煙草轉基因植株。 -
Phytoene desaturase ( pds ) has recently been identified as an important enzyme in carotenoid metabolitic pathway. a new full - length cdna clone encoding phytoene desaturase gene was isolated from stigma of saffron using rt - pcr and race techniques ( ( genbank accession no. ay 183118 ) )
其中主要的活性成分是西紅花甙，需經類胡蘿卜素代謝途徑合成，而八氫番茄紅素脫氫酶（ phytoenedesaturase ）是此途徑中的一個早期關鍵酶。 -
For prokaryotic expression, the coding region of the cdna of the phytoene desaturase gene was cloned by pcr and inserted into a prokaryotic expression vector pet - 21a ( + ). the gene was overexpressed in e. coli bl21 ( de3 ) and gave rise to a 63 kd mature protein in response to the iptg induction
用pcr方法擴增番紅花八氫番茄紅素脫氫酶（ pds ）編碼區序列，定向克隆到表達載體pet一藝1a （ + ）上，獲得重組質粒pet一21a （ + ） / cspds 。 -
Northern blot analysis showed higher expression level of pds gene in the stigma and anther than in the leaf and stem. the information we have got is very important for the further research of gene structure, expression and function of phytoene desaturase
此基因的克隆，為深入研究八氫番茄紅素脫氫酶基因結構、表達和調節機制及其結構和功能的關系奠定了重要的基礎。 -
Sequence analysis showed highly similarity to other plants such as narcissus pseudonarcissus., and they all possess a short highly conserved n - terminal sequence encoding a dinucleotide cofactor binding site. thus it is a new member of phytoene desaturase gene family
由此可認為該番紅花八氫番茄紅素脫氫酶基因在結構上與其它植物八氫番茄紅素脫氫酶基因是同源的，是八氫番茄紅素脫氫酶基因家族中的一個新成員。
