測序后在genebank上進行序列比較，該基因片段同編號為2634966的枯草芽孢桿菌全序列的2599451到2812870 （功能未知）有85的同源性，但同已發表的13種幾丁質酶的基因（包括枯草芽孢桿菌幾丁質酶基因）的同源性很低，只有30 。In this paper, the whole process of it microsporogenesis and male gametophytes development was observed with microscope to sure weather stamen development is normal. at the same time, in order to provide techniques on biotechnology conservation and the foundation of its resources gene pool in cell engineering, its techniques on culture in vitro was studied
本論文通過對蝟實小孢子發生和雄配子體發育全過程進行細胞觀察，探尋蝟實的雄性器官的發育是否是蝟實有性生殖的薄弱環節，並對蝟實的離體培養進行了初步的研究，為蝟實生物技術保存、建立蝟實種質資源基因庫提供細胞工程方面的途徑和技術。In sporophytically self - incompatible brassica, three s - linked genes, the pollen ligand scr, stigma receptor slg and srk, have been identified. in addition, four genes ( arc1, thl1, thl2 and mod ) that do not link to s locus have also been found, they are regarded as downstream protein factors of self - incompatibility ( si ) response, however, their biological function is not clear
在孢子體型自交不親和的蕓薹屬中，已經鑒定出3個主要與s位點緊密連鎖的基因，花粉中的配體scr和柱頭中的受體slg與srk ：另外鑒定出4個不與s位點連鎖的基因arc1 、 thl1 、 thl2和mod ，它們被認為是si反應的下游蛋白質因子，但是對它們的生物學功能了解的還比較少。With the aim of increasing the expression and stability of mtxl, the mtxl gene originated from b. sphaericus ssii1 was cloned to a shuttle vector pbu4. two recombinant plasmids pmt9 and pmt4 were obtained, with the inserted fragments in the opposite orientations
為了提高mtx1殺蚊毒素蛋白的表達量和穩定性，本文將來源於球形芽孢桿菌b . sss - 1的mtx1毒素基因克隆至穿梭載體pbu4上，得到mtx1插入方向相反的重組質粒pmt9和pmt4 。This review briefly summarizes the research progress on phytases from bacillus subtilis in effect mechanism, property, isolation, purification and taxonomy of the enzyme and gene engineering to speed up the deep research and exploitation of the enzyme
主要綜述了枯草芽孢桿菌植酸酶作用機理、酶學性質、分離純化、分類地位和基因工程方面的研究進展，以便為該酶的深入研究和應用提供借鑒作用。Four colonies of transformed e. coli dh5 a with clear hydroiyzing zone on the chitin agar were obtained. the gene fragment in these isolates was identified by the methods of plasmid processing. dna sequencing analysis showed that sequence homology between pcr fragment and chromosomal dna of b. subtilis from 2599451 to 2812870 was 85 %, and was 30 % between the fragment and the genes encoding for chitinase of bacillus ( including b. subtilis ) in genebank
測序並序列比較結果表明該基因片段同已發表的枯草芽孢桿菌幾丁質酶和內切葡聚糖酶編碼幕因的克隆及重組芽抱桿菌的構建glyb一apre之間的同源性是最高的，為35 % ;同bacz 』了了ussp . bp23ce1b 、 b . p朋刀us內切葡聚糖酶和b . pol理vxap一1 ， 4一內切葡聚糖酶的編碼基因的同源性只有27 % 。Screening of a potato genomic library with a full - length sb401 cdna resulted in the isolation of six positive clones. one of clones, designated 901, was further characterized
