  1. To dress the question if other virulence gene were present in this kind of strains, 152 of 436 irp2 - hybridized strains were re - confirmed and selected for this study. the virulence genes or putative virulence genes detected by pcr or hybridization include heat stable toxin ( st ) & heat labile toxin ( lt ) for enterotoxigenic e. coli ( etec ), invasive plasmid antigen b ( ipab ) for enteroinvasive e. coli ( eiec ), epec adherence factor ( eaf ), epec secretion protein c ( espc ) for enteropathogenic e. coli ( epec ), hemolysin ( hlya ) and shiga toxins ( sltl and slt2 ) for enterohaemorrhagic e. coli ( ehec ) and eaggec probe for entero - aggregative e. coli ( eaggec ). the prra and yc73 genes of pathogenicity associated island ( pai ) of urepathogenic e. coli ( upec ) and " o " island 28 ( rtx 615 ) gene was also detected, the later was a newly discovered putative pathogenicity island in e. coli o157 : h7

    為探討攜帶小腸結腸炎耶爾森氏菌的hpi毒力島的大腸桿菌是否具有其他已知的毒力基因,選取82株由原位雜交和pcr方法初篩irp2陽性的大腸桿菌菌株,進行在致瀉性大腸桿菌的25個毒力基因的檢測,包括腸產毒性大腸桿菌的熱穩定毒素st和熱不穩定毒素lt ,腸侵襲性大腸桿菌的侵襲蛋白b基因ipab ,腸致病性大腸桿菌的eafespc基因,腸出血性大腸桿菌的溶血素hly 、志賀毒素1 ( slt1 ) 、志賀毒素2 ( slt2 )基因,腸集聚性大腸桿菌的eaggec探針,以及在泌尿道致病性大腸桿菌和o157 : h7大腸桿菌中新發現的毒力島基因。

    其中eaf是用來熔化廢鋼、升溫和必要的精煉,如脫磷、脫碳的設備。
  3. The phylogenic relation and similarity of the gene is full length of lfy - like gene, which is 99 % similar both in nucleic acid sequence and amino acid sequences with that of ginlfy f rom the female. compared with the ginlfy of female, the gene from the male tree is deficient in 3 bp, and mutantion sites exists on the varied region of lfy - like

    該基因與文獻報道的銀杏雌株leafy基因相比,核苷酸序列同源性高達99 ,蛋白質序列同源浙江大學博士學位論文摘要性達99 ,缺少了3個核昔酸,突變均在植物leaf 』 y基因的非保守區內。
  4. In order to form a chloroplast transformation system of d. salina, we have conducted some studies including its sensitivity to antibiotics, the activity of promoter, cloning of the chloroplast genes and construction of transformation vectors, so far a pilot transformation system of the d. salina chloroplast has been completed. methods : the sensitivity of d. salina to seven antibiotics or herbicide used commonly in gene engineering was studied and the biological activity of atpa promoter from c. reinhardtii chloroplast was tested by using enhanced green fluorescent protein ( egfp ) as a reporter. primers were designed in the conservative encoding regions according to the chloroplast genomes from four algae which have close genetic relationship with d. salina, and the sequences of 16s rrna, chll and chln of d. salina chloroplast were cloned and sequenced, respectively

    方法:根據杜氏鹽藻的近緣藻類的葉綠體基因組序列資料,在基因編碼區的高度保守區域設計引物,克隆了杜氏鹽藻葉綠體165識na基因、咖l基因和ch n基因,並分別以165識na基因和chln基因序列為同源片段,以cat和bar基因為篩選標記基因構建了三套杜氏鹽藻葉綠體轉化載體: 2鄭州大學2003年博士學位論文杜氏鹽藻( d ~ iiellasalina )葉綠體轉化研究pds165一eaf 、 ptn1269一bar和psp72一5一bar一3 ,用基因槍法轉化杜氏鹽藻,初步建立起杜氏鹽藻葉綠體轉化體系。
  5. Lfy and lfy - like proteins from angiosperm contain a proline - rich region near the amino terminal and an acidic central region which is typical for transcriptional activators and may be important for the function of lfylike protein. the two domain exists in the variable regions of all lfy - like proteins

    與擬南芥leaf 』 y基因相比較,銀杏ginlfy和g毗基因沒有做為轉錄激活區域的位於氨基酸序列中間的酸性區和位於n端的富含脯氨酸區,但這兩個區域均位於leafy基因的非保守區。
