Secondary Pollen Presentation and a Curious Rupture of the Style in Spigelia (Spigeliaceae, Gentianales)

Plant Biology, 1999
Abstract: In the genus Spigelia (Spigeliaceae, Gentianales) we report for the first time the phenomenon of secondary pollen presentation. In Spigelia anthelmia, S. marilandica, and S. splen‐dens a deposition mechanism as found in some members of the Rubiaceae could be observed in living material. In Spigelia longi‐flora, S. sellowiana, and S. speciosa

Convergent elaboration of apocarpous gynoecia in higher advanced dicotyledons (Sapindales, Malvales, Gentianales)

Nordic Journal of Botany, 1983
The apocarpous gynoecia of three separate groups of higher advanced dicotyledons show postgenital fusion of their apical parts. In this fused region the pollen tube transmitting tissue of the carpels is united into a compitum, which provides advantages of a syncarpous to the apocarpous gynoecium. It is supposed that in at least some of these groups the

Transposable elements in Coffea (Gentianales: Rubiacea) transcripts and their role in the origin of protein diversity in flowering plants

Molecular Genetics and Genomics, 2008
Transposable elements are major components of plant genomes and they influence their evolution, acting as recombination hot spots, acquiring specific cell functions or becoming part of protein-coding regions. The latter is the subject of the present analysis. This study is a report on the annotation of transposable elements (TEs) in expressed sequences

Endomycorrhizas in the Gentianales: Structures and Evolution of the Vesicular- Arbuscular Mycorrhiza (VAM)

2003
In 1885, Frank created the term mycorrhiza [1]. Therefore, the symbiotic associations between flowering plants and fungi have been known for more than a century. Vesicular-arbuscular mycorrhiza (VAM) is the most common symbiosis in flowering plants, where almost all show VAM at some stage in their development. Although the roots of the flowering plants
