OBJECTIVE: To construct the recombinant plasmid pPHU281_A_Spec_B, which knock out Porphyrmonas gingivalis (Pg) FimA gene. METHODS: Genomic DNA was extracted from PgATCC33277 which was cultured in anaerobic condition. The upstream and downstream gene of FimA was cloned from Pg genenomic DNA with specific restriction sites by polymerase chain reaction. Suicide vector pPHU281 was inserted by three fragments: upstream, downstream of FimA gene and spectinomycin resistance gene...

The isiAB genes have proven to be highly stress-responsive under a variety of environmental conditions, including iron deficiency, high salt and oxidative stress. In order to understand the function of IsiA and its importance in oxidative stress, we constructed a knock out mutant of the isiA gene and compared differential gene expression of the DeltaisiA strain in the presence and absence of H2O2. We used the full genome microarray for the cyanobacterium Synechocystis sp. PCC 6803 as previously described [Postier BL, Wang HL, Singh A, Impson L, Andrews, HL, Klahn J, Li H, Risinger G, Pesta D, Deyholos M, Galbraith DW, Sherman LA and Burnap RL (2003) BMC Genenomics 4: 23-34]...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
