ProteomicsPerception of the peptide hormone Systemin
Cell suspension cultures of Solanum peruvianum were subjected to stimulation with 10nM systemin, the inactive systemin analog10nM a17, or injected with equal volume of water. For each treatment, a batch of cells was harvested after 2 minutes, 5 minutes, 15 minutes and 45 minutes. Untreated cells wer...

ProteomicsPhosphorylation landscape on time-resolved SYR1-dependent systemin signaling pathway
Systemin was identified in 1991 as the first plant signaling peptide, and is required for defense against insect herbivores and necrotrophic pathogens in tomato plants. Systemin was first conceived as a hormone-like, long-distance messenger mediating the activation of systemic defense responses far ...

ProteomicsSystemin-induced resistance against Botrytis cinerea in tomato plants. UHPLC-MS/MS
In this study, tomato plants were exogenously treated with either 20nM of he peptide systemin at 20nM or water by soil drenched. 24 hours after the treatment, tomato plants were challenged with the necrotrophic fungus Botrytis cinerea. We performed proteomic, metabolomic and enzymatic studies to dec...

ProteomicsPhosphorylation profiling of phytocytokine versus MAMP signaling reveals systemin-specific signaling events
Plasma membrane-localized pattern recognition receptors (PRRs) percieve host-derived phytocytokines (e.g. systemin) and microbe-associated molecular patterns (MAMPs; e.g. flg22 and chitin). Upon ligand binding, activation of PRRs induces similar early phosphorylation-regulated responses including ex...
