Only a handful of endogenous peptide defense signals have been isolated from plants. Herein, we report a novel peptide from soybean (Glycine max) leaves that is capable of alkalinizing the media of soybean suspension cells, a response that is general

GmSubPep, a 12-amino acid peptide isolated from soybean leaves, induces the expression of genes in soybean suspension-cultured cells that encode proteins involved in defense against pathogens. The peptide is derived from an extracellular subtilisin-l

A family of peptide signaling molecules (AtPeps) and their plasma membrane receptor AtPepR1 are known to act in pathogen-defense signaling cascades in plants. Little is currently known about the molecular mechanisms that link these signaling peptides

Rapid Alkalinization Factor (RALF) is a 49-amino acid peptide initially isolated from tobacco leaves that is capable of arresting both root and pollen tube growth. With suspension cells, addition of RALF causes an elevation of the pH of the extracell

Among the arsenal of plant-derived compounds activated upon attack by herbivores and pathogens are small peptides that initiate and amplify defense responses. However, only a handful of plant signaling peptides have been reported. Here, we have isola

Rapid Alkalinization Factors (RALFs) are plant peptides that rapidly increase the pH of plant suspension cell culture medium and inhibit root growth. A pollen-specific tomato (Solanum lycopersicum) RALF (SlPRALF) has been identified. The SlPRALF gene

Pep1 is a 23–amino acid peptide that enhances resistance to a root pathogen, Pythium irregulare. Pep1 and its homologs (Pep2 to Pep7) are endogenous amplifiers of innate immunity of Arabidopsis thaliana that induce the transcription of defense-rela

A gene encoding a preprohydroxyproline-rich systemin, SnpreproHypSys, was identified from the leaves of black nightshade (Solanum nigrum), which is a member of a small gene family of at least three genes that have orthologs in tobacco (Nicotiana taba

AtPep1, a 23-amino acid peptide recently isolated from Arabidopsis leaves, induces the expression of the genes encoding defense proteins against pathogens. We investigated the structure–activity relationship of AtPep1 with its receptor, a 170 kDa l

A mixture of three homologous bioactive hydroxyproline-rich glycopeptides (HypSys peptides) of 18 amino acids in length, differing only at two residues, was isolated from leaves of Ipomoea batatas, the common sweet potato. One of the peptides represe
