Embryonal Antigens in Maize Caryopses: The Temporal Order of Antigen Accumulation during Embryogenesis

Khavkin, E. E.; Misharin, S. I.; Ivanov, Vladimir N.; Danovich, K. N.

The sequential appearance of a specific group of embryonal antigens (EA), presumably globulins, was demonstrated in developing maize (Zea mays L.) caryopses using a double immunodiffusion test with absorption of common antigens. Cross immunoelectrophoresis was employed to follow the differential pattern of EA accumulation in the growing scutellum and embryonic axis. The transient nature of two predominant EA seems to indicate their role as specific protein reserves of embryonal tissues. Another presumably organ-specific EA was maintained in callus obtained from a 28-day-old culture of scutellum isolated from the mature non-germinated caryopsis.
