Nitrogen-reponsive transcriptome of a mutant strain of Nostoc sp. PCC 7120 lacking nsiR3 (ΔnsiR3)

In order to identify possible RNAs regulated by small RNA NsiR3 we have analyzed the responses to nitrogen removal in a mutant lacking nsiR3 (ΔnsiR3). RNA samples were isolated from cells growing in the presence of combined nitrogen (ammonium) or after 8 h of nitrogen deprivation. Nitrogen deprivation-induced expression in Nostoc sp. PCC 7120 (ΔnsiR3 strain) was measured in cells subjected to nitrogen deprivation for 0 and 8 hours. Two different experiments were performed for each time-point.
