Glycoproteins released from carrot cells into culture media were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and visualized by staining with Coomassie brilliant blue or with the periodic-acid Schiff procedure. The appearance or disappearance of two glycoproteins of Mr 65,000 (GP65) and Mr 57,000 (GP57) was closely related to the formation of somatic embroys. GP65 was released specifically from embryogenic cells cultured in a medium without 2,4-dichlorophenoxyacetic acid, in which they can form somatic embryos. GP57 was released from the same embryogenic cells, if they were cultured in a medium with 2,4-dichlorophenoxyacetic acid, in which they cannot form somatic embryos. Nonembryogenic cells which cannot form somatic embryos, released only GP57.
