Abstract

Treatment of cell suspension cultures of soybean, alfalfa, or tobaccowith macromolecular elicitors resulted in the release of low molecular mass (500-2000 u (Dal)) endogenous elicitors that could pass througha dialysis membrane into the surrounding culture medium. The active compounds induced phenylalanine ammonia-lyase (PAL) activity in cells of all three species, isoflavonoid phytoalexin accumulation in soybean and alfalfa cells, and an oxidative burst in soybean cells. Release offactors from soybean cells was inhibited by the RNA synthesis inhibitor actinomycin D, but not by diphenylene iodonium, an inhibitor of theoxidative burst. The activity of the factors released from tobacco cells in response to the proteinaceous elicitor cryptogein, or from alfalfa cells in response to yeast elicitor, was unaffected by pretreatment with sodium periodate or proteinase K. In contrast, treatment of thefactor(s) from soybean cells with proteinase K or trypsin destroyed its ability to induce the phytoalexin glyceollin. Ion-exchange chromatography revealed that the active material from cell cultures of each species consisted of at least two components. One component released from soybean cells appears to be a small peptide.
