Transcription profile of T. thermophilus HB8 strain lacking mutS, mutL, or mutS2 gene

ABSTRACT: We analyzed the expression profile of mutS, mutL, or mutS2 deletion mutant strain of Thermus thermophils HB8 during the exponential growth phase. When compared with wild type using t-test (P < 0.01), 8, 111, and 18 genes were over 2-fold up-regulated in mutS, mutL, and mutS2-lacking strains, respectively. Keywords: cell type comparison Wild-type and the mutant strains were precultured in 3 mL of rich medium for two times at 70°C and then subcultured to 1000 mL of rich medium. These cells were cultured at70°C for 300 min , and then cells were harvested from 50 ml of the culture. Total RNA were extracted from wild-type and mutant strains and used for the cDNA synthesis by SuperScript II (Invitrogen, Carlsbad, CA). The cDNA fragments were labeled with GeneChip DNA Labeling Reagent (Affymetr
