Phylogenetic relationships within the Gentianales based on NDHF and RBCL sequences, with particular reference to the Loganiaceae

American Journal of Botany, 2000
Phylogenetic relationships in the Gentianales with focus on Loganiaceae sensu lato are evaluated using parsimony analyses of nucleotide sequence data from the plastid genes rbcL and ndhF. Inter‐ and intrafamilial relationships in the Gentianales, which consist of the families Apocynaceae (including Asclepiadaceae), Gelsemiaceae, Gentianaceae ...

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

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

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

Suppression of Mediterranean Fruit Fly (Diptera: Tephritidae) With Trimedlure and Biolure Dispensers in Coffea arabica (Gentianales: Rubiaceae) in Hawaii

Journal of Economic Entomology, 2017
To assess the potential to suppress Mediterranean fruit fly, Ceratitis capitata (Wiedemann; Diptera: Tephritidae), via mass trapping with Trimedlure (TML), we compared fly catch (as catch per trap per time period) provided by either a novel, solid, triple-lure dispenser with TML, methyl eugenol (ME), and raspberry ketone (RK) (TMR) or solid TML plugs ...

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

Les Eumolpinae (Col. Chrysomelidae) des Apocynaceae et des Asclepiadaceae (Gentianales)

Bulletin mensuel de la Société linnéenne de Lyon, 1982
Certains Eumolpines nord-américains, euro-asiatiques et africains ont développé une sélection pour les Asclépiadacées et les Apocynacées, mais cette sélection générale du groupe est souvent plus restreinte au niveau spécifique. La monophagie d'une espèce d'Eumolpine est souvent stabilisée envers un genre végétal donné (monophagie du troisième degré ...
