Peptide signaling in Hydra

Characterization of HyNaCs - peptide-gated DEG/ENaCs from Hydra magnipapillata

Peptide signaling in plants.

I plants, only a few peptides have been identified that act as signaling molecules (1). In contrast, signaling peptides are major players in all aspects of the life cycle in animals and yeast (2), suggesting that signaling mechanisms across the eukaryotic kingdom are fundamentally different. In animals and yeast, signaling peptides are synthesized, in general, as part of longer biologically ina...

Peptide Signaling

The study of peptide signaling is yielding both fascinating and valuable information regarding bacterial biofilm development and helping to elucidate the disease processes caused by several human pathogens. Peptide signaling potentially impacts all stages of the biofilm “life-cycle” for many bacterial species, from attachment to maturation and detachment. While the particular roles of the signa...

Hydra

What is Hydra? Hydra is a member of the animal phylum Cnidaria. This phylum includes corals, sea anemones and jellyfish. While most cnidarians are marine, Hydra is unusual in that it lives exclusively in fresh water. Hydra was first described by Antoni van Leeuwenhoek (1632– 1723) in a letter he sent to the Royal Society on Christmas day, 1702. The letter included a red chalk drawing of Hydra o...

Peptide Signaling in Plant Development

Cell-to-cell communication is integral to the evolution of multicellularity. In plant development, peptide signals relay information coordinating cell proliferation and differentiation. These peptides are often encoded by gene families and bind to corresponding families of receptors. The precise spatiotemporal expression of signals and their cognate receptors underlies developmental patterning,...
