Project description:Caecal contents from three specific pathogen-free (SPF) mice, and three germ-free (GF) mice were analyzed by DIA-MS (SWATH-MS) using TripleTOF 5600+ (SCIEX). Paraprevotella clara (P. clara) culture supernatants nontreated and treated tunicamycin or 2-fluro-L-fucose (2F-Fuc) were analyzed by DIA-MS using Q Exactive HF-X (Thermo Fisher Scientific). In addition, GF mouse caecal contents were incubated with P. clara or medium control. Supernatant samples were collected at the indicated time points and subjected to peptidome analysis using Q Exactive HF-X (Thermo Fisher Scientific).
Project description:Molecular genetic analyses support a central role of BZR1 in Brassinosteroid (BR) regulation of plant development. The dominant bzr1-1D mutation, which stabilizes the BZR1 protein, completely suppresses the de-etiolated phenotype of the null bri1-116 mutant grown in the dark. Using microarray analysis, we identified genes differentially expressed in bri1-116 compared to wild type and genes differentially expressed in the bzr1-1D;bri1-116 double mutant compared to the bri1-116 single mutant. Consistent with the phenotypic suppression of bri1-116 by bzr1-1D, about 80% of the genes affected in bri1-116 were affected oppositely by bzr1-1D
