Elaioplast is the final stage of tapetal plastid development (Fig.
First, in strictly anemophilous species, such as Lolium perenne, plastids first develop into chromoplast, later in elaioplast, and then are resorbed with the other tapetal cell components (Pacini et al.
Finally, prior to tapetum degeneration, elaioplast lipids mix with spherosomes and constitute the main part of the pollenkitt, which will reach the pollen wall (Fitzgerald et al.
2010) studied the molecular mechanism of HMGS involved in development of tapetum-specific organelles and fertility of pollen grains, and found that the MVA pathway is essential for development of both tapetosomes and elaioplasts in tapetal cells and for pollen viability, at least during pollen tube elongation.
Whether the initiation or chemical composition of tapetosomes or elaioplasts (Piffanelli & Murphy, 1998) is related to pro-orbicules is unknown.
