“…Tapetal malfunction is commonly described as a major factor in the development of male sterility (Laser and Lersten 1972;Rai and Stoskopf 1974;Chauhan 1979) as the tapetum plays a nutritive role in the formation of the pollen grains (Echlin 1971). Tapetal behaviour in cytoplasmic male sterile wheat ranges from premature degeneration (Chauhan and Singh 1966) through no change from the normal fertile condition (De Vries and Ie 1970) to delayed degeneration (Chauhan and Singh 1966;Joppa et al 1966;Chauhan and Kinoshita 1980;Jain et al 1981), depending on the source of the sterility. Premature degeneration resulting in an invasive periplasmodium has been described previously in wheat (Chauhan and Singh 1966;Jain et al 1981) and also in a number of other species (see Scoles and Evans 1979) and appears to be a common manifestation of male sterility.…”

The importance of contact between the microspores and the tapetum and the specific orientation of the pore during normal pollen development has been stressed by a number of authors (Batygina 1962;Christensen and Horner 1974;Scoles and Evans 1979).…”

An anatomical survey of anthers of the Poaceae and Cyperaceae and two related families, the Restionaceae and Flagellariaceae, was conducted to determine the taxonomic distribution and possible phylogenetic significance of pollen arrangement. An unusual pollen arrangement was known from a small number of taxa in the Poaceae and Cyperaceae, in which a single, uniseriate cylinder of pollen grains is arranged in the anther locule such that each grain is in contact with the tapetum (termed here “peripheral” pollen). This contrasts with the prevailing arrangement in other angiosperms in which the locule contains a relatively large number of pollen grains in no special configuration, with many interior grains that never touch the tapetum (termed here “central” pollen). A total of 48 species in these four families was examined in this study, and observations on pollen arrangement for numerous additional species in these families were gleaned from the literature. We confirm that the peripheral arrangement is predominant in Poaceae and Cyperaceae, although both families also include species with central pollen, whereas only central pollen is found in Restionaceae and Flagellariaceae. In the peripheral arrangement, the pore of the pollen grain or pseudomonad, when observed, is in contact with the tapetum, but it has not been definitively demonstrated that this is always the case. Peripheral pollen in the Poaceae and Cyperaceae is nonhomologous because of the presence of pseudomonads in the latter family. It remains unexplained why peripherally arranged pollen or pseudomonads, with the attendant reduction in the number of pollen grains, should be associated with anemophily in these two families.
