title: [Identification of a new bioregulator acting in ultralow doses in bulb onion (Allium cepa L.)].
abstract: A bioregulator that has physicochemical and biological properties similar to a group of bioregulators isolated from various animal tissues has been found in the bulb onion (Allium cepa L.). It was determined that the biological action of the plant bioregulator is determined by a peptide with molecular weight of 4036 +/- 2 Da whose 18-C-terminal amino acid sequence consisted of 18 residues. On models of seed germination of some vegetable cultures, the ability of the bioregulator isolated from supernatant of onion extract in ultralow doses (10(-13) mg of protein/ml) to inhibit growth and development was demonstrated.
