例句与用法

	1.	Gene deletion to decrease acetic acid yield of saccharomyces cerevisiaes 6基因降低啤酒酵母产乙酸量
	2.	Effect of avec gene deletion on avermectins production in streptomyces avermitilis 基因缺失对产素调控的影响
	3.	Analysis of dna microarray assay of progressive muscular dystrophy gene deletions 微阵列对进行性肌营养不良基因缺失检测的分析
	4.	2 . the sequence of si gene from ibv - lx4 strain was consisted of 1614 bp from initiation codon atg to the possible cleavage site of spike glycoprotein , encoding for a 18 - amino signal - peptide with the n terminus of si protein and a polypeptide of 537 - amino acids . 19 highly conserved , potential glycosylation sites and 17 cysteines residues were characterized with si protein , homology analysis showe that there were gene deletion - S1基因：其全序列共1614bp (从起始密码子atg到s前体蛋白裂解位点) ，编码537个氨基酸，其氨基端有一编码18个氨基酸的信号肽序列，第12 13位氨基酸残基构成了信号肽的切割位点， 14 19位与111 124位氨基酸残基为s1蛋白的跨膜区域。
	5.	In addition to avermectins , s . avermitilis produces oligomycin , a strongly toxic compound . gene deletion vector pxl05 was used to disrupt oligomycin polyketide synthase ( pks ) encoding genes ( olma ) in streptomyces avermitilis cz8 - 73 , the producer of anthelmintic avermectins b and the cell growth inhibitor oligomycin . olma gene cluster in the chromosome was displaced by deletion allele on the plasmid via double crossover 本研究以产阿维菌素b和寡霉素的阿维链霉菌cz8 - 73为出发菌株，构建了基因缺失载体pxl05 ，并将其转入cz8 - 73中，通过缺失载体和染色体之间的同源双交换，对染色体上长达90kb的寡霉素聚酮合酶( pks )基因簇( olma )进行了缺失。
	6.	Shaking flask experiments and hplc analyses showed that the four mutants no longer produced the toxic oligomycin , and only made four components of avermectins b , which were avermectin b1a , b1b , b2a , b2b . the yields of avermectins b in these mutants were separately equal to those in cz8 - 73 . this revealed that olma genes deletion did n ' t affect the biosynthesis of avermectins 将4株经southern杂交验证正确的基因缺失突变株进行摇瓶发酵和hplc检测，发现4个突变株均不再产生寡霉素而仅产阿维菌素b组分，阿维菌素的总产量和b1的产量与出发菌株相当，说明寡霉素pks基因簇的缺失并不影响阿维菌素的生物合成。
