Project description:The alkaliphilic halotolerant bacterium Bacillus sp. N16-5 often faces salt stress in its natural habitats. One-color microarrays was used to investigate transcriptome expression profiles of Bacillus sp. N16-5 adaptation reactions to prolonged grown at different salinities (0%, 2%, 8% and 15% NaCl) and the initial reaction to suddenly alter salinity from 0% to 8% NaCl.

Project description:We used microarrays and a previously established linkage map to localize the genetic determinants of brain gene expression for a backcross family of lake whitefish species pairs (Coregonus sp.). Our goals were to elucidate the genomic distribution and sex-specificity of brain expression QTL (eQTL) and to determine the extent to which genes controlling transcriptional variation may underlie adaptive divergence in the recently evolved dwarf (limnetic) and normal (benthic) whitefish. We observed a sex-bias in transcriptional genetic architecture, with more eQTL observed in males, as well as divergence in genome location of eQTL between sexes. Hotspots of nonrandom aggregations of up to 32 eQTL in one location were observed. We identified candidate genes for species pair divergence involved with energetic metabolism, protein synthesis, and neural development based on co-localization of eQTL for these genes with eight previously identified adaptive phenotypic QTL and four previously identified outlier loci from a genome scan in natural populations. 88% of eQTL-phenotypic QTL co-localization involved growth rate and condition factor QTL, two traits central to adaptive divergence between whitefish species pairs. Hotspots co-localized with phenotypic QTL in several cases, revealing possible locations where master regulatory genes, such as a zinc finger protein in one case, control gene expression directly related to adaptive phenotypic divergence. We observed little evidence of co-localization of brain eQTL with behavioral QTL, which provides insight on the genes identified by behavioral QTL studies. These results extend to the transcriptome level previous work illustrating that selection has shaped recent parallel divergence between dwarf and normal lake whitefish species pairs and that metabolic, more than morphological differences appear to play a key role in this divergence.

One-color microarrays was used to investigate transcriptome expression profiles of Bacillus sp. N16-5 adaptation reactions to prolonged grown at different salinities (0%, 2%, 8% and 15% NaCl) and the initial reaction to suddenly alter salinity from 0% to 8% NaCl. Salt induced gene expression was measured when culture was grown on different salinities (0%, 2%, 8% and 15% NaCl) to mid-logarithmic phase. And salt induced gene expression was also measured at 0 min, 10 min, 30 min, 60min, 120min after a sudden change salinity from 0% to 8% NaCl.
