Ultrastructure of the stigma and style of Cabomba caroliniana Gray (Cabombaceae)
Cabomba Aubl. is a genus that presents a range of features that have made it to be considered a potential genetic model for studies of early angiosperm evolution. Therefore, any study that expands our knowledge of this genus is potentially useful for the understanding of the evolution of early angio...

| 520 | |a Cabomba Aubl. is a genus that presents a range of features that have made it to be considered a potential genetic model for studies of early angiosperm evolution. Therefore, any study that expands our knowledge of this genus is potentially useful for the understanding of the evolution of early angiosperms. This paper reports the study of the anatomy and the ultrastructure of the stigma and the style of Cabomba caroliniana Gray during the 2 days of anthesis using bright-field microscope, fluorescence microscope and transmission electron microscope. The stigma is dry and has pluricellular papillae. The style is hollow with a central canal coated by an epithelium. The papillae have fewer organelles than those typical of glandular cells, and they are covered by a cuticle that is broken when pollen germinates. The ultrastructure of epithelial cells indicates that the cells lining the canal are secretory. The canal is filled with a fibrillar and granular substance. The pollen tubes grow inside the canal through this substance. The results are discussed in the context of what is known for other species of angiosperms. | ||
