In differentiated cells, plastids can be involved in anabolism (chloroplasts) or in storing reserves in amyloplasts and elaioplasts (Wheatley, 1977).
Second, in entomophilous species, elaioplasts produce large amounts of lipids in their stroma, which are released into the cytoplasm through the plastid envelopes prior to tapetal plasma membrane disruption (Heslop-Harrison, 1968; Dickinson & Lewis, 1973; Pacini & Juniper, 1979b; Reznickova & Willemse, 1980, 1981; Reznickova & Dickinson, 1982; Keijzer & Willemse, 1988b; Murgia et al., 1991; Pacini et al., 1992a; Weber, 1992, 1996; Hesse & Hess, 1993; Hess & Hesse, 1994).
Both tapetosomes and elaioplasts are involved in the formation of tapetal lipids that are released in the locule to form tryphine (Dickinson & Lewis, 1973) by extra situm degeneration (Pacini & Franchi, 1991).
In the tapetum, plastid divisions may occur either before lipid accumulation, as in Cucurbita (Ciampolini et al., 1993), or when elaioplasts are already differentiated, as in Lilium (Clement et al., 1998).
One reason may be pollination type, which influences the resorption (or not) of tapetal elaioplasts and the physicochemical properties of pollenkitt.
