[Wolfgang Schmidt] Small but pack a punch: Plant peptides call the tune

Small regulatory peptides, short chains of amino acids linked by peptide bonds, control a plethora of pivotal biological processes in plants. Although considerable progress has been made over the past two decades in deciphering their role in developmental and signaling pathways, many facets of the biogenesis, function and molecular mechanisms by which peptides act in plants remain to be clarified. A multinational editor team put together a suite of review and original articles that provide insights into the fascinating world of peptide signaling, covering a wide range of topics including methods for the large-scale mining of novel peptides. The article collection is published as a Research Topic in Frontiers in Plant Science.
