Project description:A genome-wide analysis of gene expression of the root-colonizing bacterium Pseudomonas putida KT2440 in the rhizosphere of corn (Zea mays var. Girona). To identify reliable rhizosphere differentially expressed genes by this bacterium, populations of P. putida KT2440 previously exposed to a rhizospheric life style for seven days in the rhizosphere of corn were compared with populations previously exposed to a rhizospheric life style for a long period of 138 days.

Project description:The purpose of this set of arrays is to provide a third replicate to use in data analysis addition to the 2 previous replicates for all samples already generated on this project. Our hypothesis is that adaptation to a calcareous environment will be reflected in altered gene expression including genes encoding transporters, ion channels, transcription factors, etc. To test this hypothesis we grew a laboratory non-calcicole (Col-4) and a laboratory calcicole (Cal-0) ecotypes of A. thaliana at low (1 mM) and high (12.5 mM) rhizospheric Ca2+ and compare the patterns of gene expression by microarray analysis. We then collected from the wild, a putative calcicole ecotype (Elland)and a putative non-calcicole (Penicuik) and grew both at low (1 mM) and high (12.5 mM) rhizospheric Ca2+ and compared expression profiles to the laboratory ecotypes.

Project description:Within the human gut reside diverse microbes coexisting with the host in a mutually advantageous relationship. We comprehensively identified the modulatory effects of phylogenetically diverse human gut microbes on the murine intestinal transcriptome. Gene-expression profiles were generated from the whole-tissue intestinal RNA of mice colonized with various single microbial strains. The selection of microbe-specific effects, from the transcriptional response, yielded only a small number of transcripts, indicating that symbiotic microbes have only limited effects on the gut transcriptome overall. Moreover, none of these microbe-specific transcripts was uniformly induced by all microbes. Interestingly, these responsive transcripts were induced by some microbes but repressed by others, suggesting different microbes can have diametrically opposed consequences.
