Project description:We constructed a tiling microarray, covering nearly all of the intergenic regions larger than 50 bp on both strands of the genome of the marine picocyanobacterium Synechococcus WH7803. We analyzed transcript levels from cultures grown under ecologically relevant stress conditions. The investigated stress conditions were cold stress, high light stress, phosphate depletion and iron depletion. We identified several previously unknown small RNAs, partially differentially expressed. The detected RNAs provide a starting point for further investigations on the acclimatisation to different stresses for Synechococcus WH7803.
