Project description:We used microarrays to discern patterns of gene expression in response to global climate change factors on leaf tissue of an annual dicot, Geranium dissectum, growing in a natural grassland. Keywords: multifactorial global change treatments There are 5-8 biological replicates for each of the sixteen treatments - a total of 100 samples. The four global change factors at two levels are ambient or elevated CO2, ambient temperature or ambient + 1 degree C warming, natural rainfall (601.2 mm/yr) or natural rainfall supplemented with 50% of every storm added immediately following each storm with a 3 week season extension, ambient growth nitrogen or ambient supplemented with 7 g N m-2 y-1, supplied as Ca(NO3)2. There were 16 treatments applied in a nested design in the field.We hybridized the Geranium samples using cross-species hybridization to Arabidopsis cDNA arrays which had an Arabisopsis genomic DNA common reference in the Cy3 channel.
Project description:We determined the set of newly acquired CRISPR spacers during naive and primed adaptation in E. coli. We compared primed adaptation when targeting different plasmid and chromosomal sites. These data provide insight into the sequence features that impact the efficiency of primed adaptation in E. coli.
