An Apparent Helical Arrangement of Ribosomes in Developing Pollen Mother Cells of Ipomoea Purpurea (l.) Roth

Behnke (1963) has recently described a helical arrangement of ribosomes in differentiating cells of the small intestine of the rat fetus, and Waddington and Perry (1963) have found the same structures in the muscle cells of Rana pipiens embryo. In the course of an investigation into the development of pollen in Ipomoea purpurea (L.) Roth, a similar arrangement of ribosomes has been seen in the ...

Close clustering of anthers and stigma in Ipomoea hederacea enhances prezygotic isolation from Ipomoea purpurea.

Theory predicts that, for taxa that are already substantially postzygotically isolated but for which hybrid mating is still costly, enhanced prezygotic isolation will be favored. Here, we tested this hypothesis by examining the potential contribution of one particular floral trait, herkogamy, to prezygotic isolation between two species of morning glory, Ipomoea hederacea and Ipomoea purpurea.
