Comparison of the expression after nitrogen stepdown of some genes likely
involved in heterocyst differentiation. Data taken from global studies carried out with
Anabaena
sp. strain PCC 7120 and
Nostoc punctiforme
. The values are expressed as fold
induction at the indicated hours after combined-nitrogen withdrawal—cont'd

*TSP: Transcriptional start point showing increased use in the wild type but not in the hetR mutant (Mitschke
et al., 2011). These TSPs were located within the upstream 200 nucleotides of the assigned ORF, except when
indicated otherwise. The TSPs corresponding to ORFs encoding unknown or hypothetical proteins with RPKM
<3 (
Flaherty et al., 2011
) are not shown in the table.
†
TSPs further upstream than 200 nucleotides of the assigned ORF, with no apparent ORF between the TSP and
the assigned ORF.
