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.

Project description:Aim; To identify genes which are differentially expressed between calcicoles and non- calcicoles. Background; Grasslands on the calcareous soils of chalk and other limestones are among the most species-rich plant communities in Europe (Rodwell 1991 et seq.). They have experienced huge losses and remain vulnerable to such impacts as neglect of traditional management, agricultural improvement and global changes in climate, nitrogen depositions and ozone levels. Our understanding of the physiological characteristics of calcicoles and calcifuges remains limited. A detailed understanding of the genetic basis of the mechanisms that enable calcicoles to thrive on calcareous soils is essential to enable us to predict how these plant communities and their constituent species will be affected by environmental change and how the biodiversity of these ecosystems can be sustained.At Lancaster we have been studying calcicole-calcifuge physiology, with particular reference to Ca2+-tolerance, for over fifteen years. Recently, our research has focused on the regulation of apoplastic Ca2+ in Arabidospsis thaliana. We have compared the response of two ecotypes of A. thaliana, the non-calcicole ecotype Columbia (Col-4) and the calcicole ecotype Cal-0, which is a genetically uniform line from an original population collected by Ratcliffe from a rocky limestone slope in 1954, to rhizospheric Ca2+. Our results show that Cal-0, exhibits a markedly higher tolerance to growth on high rhizospheric Ca2+ compared to Col-4.Our hypothesis is that adaptation to a calcareous environment will be reflected in altered gene expression. To test this hypothesis we will grow Col-4 and Cal-0 at low (1 mM) and high (12.5 mM) rhizospheric Ca2+ and compare the patterns of gene expression by microarray analysis. In the first instance, to eliminate any differences in gene expression between the Cal-0 and Col-4 ecotypes, we will compare RNA that will be extracted using the Qiagen RNEasy kits, from plants grown at 16 hour day lengths and will be harvested after 30 days of growth on sand watered with 0.5 X Long Ashton solution containing 1 mM CaCl2.
