Proteins as Morphogenetic Markers in Callus Cultures of Buckwheat Fagopyrum tataricum (L.) Gaertn with Different Morphogenetic Potential

The content of soluble proteins and individual polypeptides was studied in calluses of buckwheat Fagopyrum tataricum (L.) Gaertn with different morphogenic potential. The morphogenic callus had a higher content of soluble proteins and cyclic pattern of changes in this index during passaging, which seems to be due to formation of proembryogenic cell complexes. Comparison of the protein patterns of the calluses demonstrated differences in composition and content of individual components. Morphogenic (35 and 73 kDa) and non-morphogenic callus-specific polypeptides (16 and 62 kDa) have been revealed.
