Constancy of wheat histones during development.
Histones were extracted from leaves of winter- and spring-wheat seedlings, flowering shoots of spring wheat, shoots of vernalized and control winter wheat, and roots and shoots of winter wheat, and were compared by polyacrylamide-gel electrophoresis. No differences were found either in the electrophoretic mobility or relative quantity of the various fractions. Wheat histones contained fractions of the exact electrophoretic mobility as F2a1 and F3 of calf thymus and pea histones. Other major fractions of the wheat histones had electrophoretic mobilities similar to those of F1, F2b and F2a2 of peas.
