The role of the tapetum in the formation of sporopollenin-containing structures during microsporogenesis in Pinus banksiana.
In the microsporangium of Pinus the outer layer of the peritapetal membrane and the pro-orbicular cores are not only formed in a similar manner, but are composed of apparently identical materials. Precursors for this lipoidal material are produced by the tapetal protoplasts, as are the precursors of...
