Project description:We employed a proteogenomics workflow to identify microproteins encoded by small Open Reading Frames (ORFs) in the genome of Mycobacterium smegmatis strain mc²155.
Project description:We report the complete 4,352,172-bp genome sequence of Mycobacterium orygis strain 51145 assembled into a single circular chromosome. Comparative genomic analyses with other lineages of the Mycobacterium tuberculosis complex can provide insights into the biology, evolution, and epidemiology of this important group of pathogenic mycobacteria.
Project description:In our study, we found that lack of tmRNA affects the biofilm formation in Bacillus subtilis, which has important research significance. Then, we obtained a revertant strain MB from tmRNA mutant strain. And MB strain could restore biofilm production capacity. Therefore, the transcriptomes of the three strains were sequenced. Based on the statistical analysis of gene expression (P < 0.05), there were 756 genes up regulated while 992 genes down regulated by at least two folds when comparing TM to WT. Secondly, there were 974 genes up regulated while 563 genes down regulated by at least two folds when comparing MB to TM. And there were 179 genes up regulated while 307 genes down regulated by at least two folds when comparing MB to WT.
Project description:In this approach, total transcript of a Mycobacterium smegmatis amtR deletion strain was compared under nitrogen surplus and starvation. This is a control experiment to the comparison of wild type and amtR deletion strain, resulting nitrogen-related genes which are not AmtR-controlled. Two biological replicates were analyzed.
Project description:In this approach, changes in total transcript of a glnR deletion strain of Mycobacterium smegmatis due to nitrogen starvation were monitored. This is a control experiment for the comparison of wild type and glnR deletion strain resulting in putative nitrogen-related genes which are not controlled by GlnR.
