The phytoalexin response of Lotus japonicus seedlings to selected microbes and chemical signals was analyzed. The symbiotic rhizobium induced vestitol production weakly, while non-symbiotic rhizobia and potential pathogens led to increases in its accumulation. Whereas chitin-related molecules were ineffective, a flagellin-derived peptide not of symbiont origin induced phytoalexin production, indicating discriminative antibiotic production by the plant host.
