Genes transformed into plants are usually inherited in a regular Mendelian manner. There are, however, transformants in which the selectable trait fails to segregate as expected. Genetic analysis of the kanamycin-resistance (KanR) trait in >900 independent transformants of Arabidopsis revealed that 9% produced progeny families with an enormous deficiency of KanR individuals. Self-pollination of...
A transformation system for Moorella thermoacetica ATCC39073 was developed using thermostable kanamycin resistant gene (kanR) derived from the plasmid pJH1 that Streptococcus faecalis harbored. When kanR with its native promoter was introduced into uracil auxotrophic mutant of M. thermoacetica ATCC39073 together with a gene to complement the uracil auxotrophy as a selection marker, it did not g...
While antimicrobial resistance in Salmonella enterica is mainly attributed to large plasmids, small plasmids may also harbor antimicrobial resistance genes. Previously, three major groups of ColE1-like plasmids conferring kanamycin-resistance (KanR) in various S. enterica serotypes from diagnostic samples of human or animals were reported. In this study, over 200 KanR S. enterica isolates from ...
The dominant kanr marker gene plays an important role in gene disruption experiments in budding yeast, as this marker can be used in a variety of yeast strains lacking the conventional yeast markers. We have developed a loxP-kanMX-loxP gene disruption cassette, which combines the advantages of the heterologous kanr marker with those from the Cre-lox P recombination system. This disruption casse...
The carbon storage regulator gene, csrA, modulates the expression of genes in the glycogen biosynthesis and gluconeogenesis pathways in Escherichia coli and has been cloned, mapped and sequenced (T. Romeo, M. Gong, M.Y. Liu, and A.M. Brun-Zinkernagel, J. Bacteriol. 175:4744-4755, 1993; T. Romeo and M. Gong, J. Bacteriol. 175:5740-5741, 1993). We have now conducted experiments that begin to eluc...
Defined Single-Gene and Multi-Gene Deletion Mutant Collections in Salmonella enterica sv Typhimurium
We constructed two collections of targeted single gene deletion (SGD) mutants and two collections of targeted multi-gene deletion (MGD) mutants in Salmonella enterica sv Typhimurium 14028s. The SGD mutant collections contain (1), 3517 mutants in which a single gene is replaced by a cassette containing a kanamycin resistance (KanR) gene oriented in the sense direction (SGD-K), and (2), 3376 muta...
زمینه و اهداف: بروسلوز از مهم ترین بیماری های مشترک انسان و دام محسوب می گردد. بهترین راه مقابله با بروسلوز انجام واکسیناسیون مناسب میباشد. واکسنهای موجود از قبیل واکسن rev1 با معایبی چون سقط جنین در حیوانات باردار همراه است لذا تهیه واکسن مناسب برای درمان بروسلوز ضروری می باشد. هدف از انجام این مطالعه، طراحی و ساخت وکتور خودکشی pds132-δkanr به منظور حذف ژن مقاومت به آنتیبیوتیک کانامایسین د...
The carbon storage regulator gene, csrA, encodes a factor which negatively modulates the expression of the glycogen biosynthetic gene glgC by enhancing the decay of its mRNA (M. Y. Liu, H. Yang, and T. Romeo, J. Bacteriol. 177:2663-2672, 1995). When endogenous glycogen levels in isogenic csrA+ and csrA::kanR strains were quantified during the growth curve, both the rate of glycogen accumulation...
BACKGROUND The bacterium Bacillus subtilis, which is not a natural riboflavin overproducer, has been converted into an excellent production strain by classical mutagenesis and metabolic engineering. To our knowledge, the enhancement of riboflavin excretion from the cytoplasm of overproducing cells has not yet been considered as a target for (further) strain improvement. Here we evaluate the fla...
