Nodulation regulation Legumes convert atmospheric nitrogen into biologically useful ammonium with the help of symbiotic bacteria housed in root nodules. Much of nodule development is controlled by the transcription factor NODULE INCEPTION (NIN). Fenget al . show that NIN is proteolytically processed to release a fragment that regulates the later stages of nodulation when the nodules acquire nitrogen-fixing capability. In related work, Jianget al . identified members of the NIN-like protein (NLP) transcription factor family as being regulators of leghemoglobin expression acting through an unusual promotor motif shared across legumes. —PJH
