Partial characterization of nitrate signaling pathway of Arthrospira platensis PCC 7345

The present study is to elucidate the signaling network involved in nitrate uptake and assimilation of Arthrospira platensis. Expression of adenylate cyclase, cyaC was found to be nitrate signal dependent. The involvement cAMP was also observed in different levels of nitrate signaled assimilatory pathway. We have used differential display to identify a histidine kinases in the nitrate signaling of Arthrospira platensis.
