Abstract
In the mature Brassica pollen grain, the outermost wall layer, the exine, is surrounded by a trilamellar structure which presents some of the morphological, cytochemical, enzymological and physico-chemical characteristics of a biological membrane. This structure, designated the exinic outer layer (EOL), has been visualized and partially characterized by electron microscope techniques. Its possible involvement in the male-female recognition reaction is discussed.Keywords
