A growing understanding is emerging of the roles of peptide hormones in local and long-distance signalling that coordinates plant growth and development as well as responses to the environment. C-TERMINALLY ENCODED PEPTIDE (CEP) signalling triggered by its interaction with CEP RECEPTOR 1 (CEPR1) is known to play roles in systemic nitrogen (N) demand signalling, legume nodulation, and root system architecture. Recent research provides further insight into how CEP signalling operates, which involves diverse downstream targets and interactions with other hormone pathways.

- Legumes use nitrogen-fixing root nodules and lateral roots for nutrient acquisition but regulate nodule number through autoregulatory and hormonal pathways.
- In Medicago truncatula, a specific hormone, SymCEP7, enhances nodule formation from the shoot while not affecting lateral root growth; this is distinct from other CEP hormones that generally inhibit lateral roots.
- SymCEP7 relies on a specific receptor and increases its activity in certain mutant conditions, and it can promote nodule development even in other plants like White Clover and Lotus, indicating a potentially conserved evolutionary function.
Unlabelled: The nucleosome remodelling and deacetylase (NuRD) complex is essential for the development of complex animals. NuRD has roles in regulating gene expression and repairing damaged DNA. The complex comprises at least six proteins with two or more paralogues of each protein routinely identified when the complex is purified from cell extracts.
