RESUMO
Lipochitooligosaccharides (LCOs) are plant growth regulators that promote at subfemtomolar concentrations cell division in tobacco protoplasts. In response to LCO treatment, tobacco cells release a second growth factor that fully mediates the growth-promoting activities of the initial extracellular LCO stimulus. This diffusible growth factor was isolated from the protoplasts' culture filtrate and shown to be a peptide. We report that the LCO-induced mitogen released by tobacco cells and a synthetic heptadecapeptide derived from region 2 of the tobacco homolog of the early nodulin gene ENOD40 are antigenically related and qualitatively indistinguishable in their ability to stimulate cell division.
