Project description:We sought to understand the change in the global gene expression profile of the ΔYGP1 strain in comparison with the BGL-6_Kl parental strain. The transcriptome analysis revealed the change in expression of genes involved in cell wall structure, biogenesis, and integrity that might contribute to the improvement of the BGL display efficiency phenotype.
Project description:To solve the problem of low FK520 production by Streptomyces hygroscopicus var. ascomyceticus FS35, PHB synthesis gene phaC and PHB decomposition gene fkbU were co-overexpressed in parent strain FS35 to construct recombinant strain OphaCfkbU. Surprisingly, recombinant strain OphaCfkbU accumulated more biomass than parent strain FS35 in whole fermentation. Therefore, to explore the effect of co-overexpression on the strain growth, comparative transcriptome analysis were carried out between parent strain FS35 and recombinant strain OphaCfkbU. Transcriptome data showed that co-overexpression increased the utilization of sugar sources and stimulated the generation of coenzymes, ribosome, acyl carrier proteins and sulfate donors. This study revealed the internal mechanism of the effect of PHB on strain growth, proving a reference for the role of PHB in other microorganisms.
Project description:Previous studies have applied genomics and transcriptomics to identify the immune and genetic markers as key indicator traits for cattle tick susceptibility/resistance, however, results differed between breeds, and host proteomics and metabolomics were not considered. We used serum samples from Santa Gertrudis cattle phenotypically divided into groups as tick-resistant (TR) and -susceptible (TS) to conduct differential abundance analyses of protein profiles between the two groups. The serum proteins were digested into peptides followed by identification and quantification by sequential window acquisition of all instances of theoretical fragment ion mass spectrometry (SWATH-MS).
Project description:To study the roles of NWMN_0641, we used microarray to compare the transcriptome of the NWMN_0641 deletion strain with that of the wild-type Staphylococcus aureus Newman strain. Transcriptome of the NWMN_0641 deletion mutant strain and the wild-type Newman strain
