Metabolite Identification
Common NameSyringolide 1
DescriptionSyringolide 1 is a phytotoxin belonging to the class of plant metabolites known as syringolides. This compound has been shown to interact specifically with soluble proteins in soybean leaf extracts, with a notable binding affinity characterized by a Kd value of 8.7 nM (PMID:12237390 ). The binding activity is attributed to a 34-kDa protein isolated using a syringolide affinity-gel column (PMID:9501258 ). Notably, syringolide 1 does not exhibit ligand-specific binding to the microsomal fraction of these extracts (PMID:12237390 ). Furthermore, competition studies indicate a direct correlation between the binding affinity of syringolide 1 and its elicitor activity, suggesting its role in plant defense mechanisms (PMID:12237390 ). In biological assays, syringolide 1 has been demonstrated to trigger significant physiological responses, such as Ca2+ influx, K+ efflux, and extracellular alkalization in soybean cells that carry the disease-resistance gene Rpg4, while showing no effect in rpg4 cultivars (PMID:12226392 ). These findings highlight the potential role of syringolide 1 in mediating plant defense responses against pathogens.
