The effects of gelatin on aggregation of protoplasts from higher plants.

Aggregation of protoplasts of Allium fistulosum L., Brassica chinensis L. and Daucus carota L. was induced in great frequency with gelatin and early products of gelatin degradation. The optimal gelatin concentration was 2-5%. The aggregated protoplasts fused into groups and cell walls were formed around them in culture.
