Van Caeseele, L. | Klinger, B. | Sumner, M.J.
Unfertilized mature ovules of Brassica L. contain an abundance of starch in the integument cells from the micropyle to a plane approximately at the level of the central cell polar nuclei. Inside the embryo sac central cell, in the coinciding region, there are transfer cell-like wall projections with plasma membranes appressed to their inner surfaces. H+-ATPase is present along the inner surfaces of the wall projections as indicated by reactivity with antibody raised against plasma membrane H+-ATPase. A number of mitochondria are in close association with wall projections in the region of the egg apparatus. Antibody raised against corn plasma membrane H+-ATPase cross reacts with a protein of the same size in extracts of Brassica napus indicating that the two species contain a similar plasma membrane H+-ATPase.
