Phylogenetic relationships, systematics, and biology of carnivorous Lamiales, with special focus on the genus Genlisea (Lentibulariaceae)

  author={Andreas S. Fleischmann},
Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our… 

The miniature genome of a carnivorous plant Genlisea aurea contains a low number of genes and short non-coding sequences

Genome contraction was a complex process, which involved gene loss and reduction of lengths of introns and intergenic regions, but not intron loss, indicating that genetic redundancy is an important prerequisite for genome size reduction.

Flower palate ultrastructure of the carnivorous plant Genlisea hispidula Stapf with remarks on the structure and function of the palate in the subgenus Genlisea (Lentibulariaceae)

The ultrastructure of the palate trichome showed that the palate glandular trichomes most probably function as scent glands that produce an olfactory stimulus for flower pollinators.



Recent progress in understanding the evolution of carnivorous lentibulariaceae (lamiales).

Studies using various molecular markers have established that Lentibulariaceae and their three genera are monophyletic with Pinguicula being sister to a Genlisea-Utricularia-clade, while the closest relatives of the family remain uncertain.

Toward a comprehensive understanding of phylogenetic relationships among lineages of Acanthaceae s.l. (Lamiales).

This study sampled all known lineages of Acanthaceae including Andrographideae and used sequence data from nrITS and four chloroplast noncoding regions, and parsimony and Bayesian methods of analysis to strongly support most aspects of relationships.

Phylogenetic placement of Triaenophora (formerly Scrophulariaceae) with some implications for the phylogeny of Lamiales

The resulting phylogeny is in agreement with other data such as phytochemistry and provides a framework for further investigation of character evolution in Lamiales.

Phylogenetic Relationships of the Monotypic Genus Amphianthus (Plantaginaceae Tribe Gratioleae) Inferred from Chloroplast DNA Sequences

The most complete phylogeny of the Gratioleae to date is presented and evidence from chloroplast DNA sequences of the ndhF gene and the trnS–trnG–trNG intergenic spacer and intron that unequivocally place Amphianthus within Gratiola is provided, and morphological evidence supporting the findings are discussed.

Phylogeny of the parasitic plant family Orobanchaceae inferred from phytochrome A.

The robust phylogenetic hypothesis inferred from the PHYA data provides a much better context in which to evaluate the evolution of parasitism within Orobanchaceae, the largest of the parasitic angiosperm families.

Evolution of carnivory in Lentibulariaceae and the Lamiales.

It is suggested that carnivory and its preliminary stages ("proto-carnivores") independently evolved more than once among Lamiales, thereby hinting at a marked degree of carnivory in these two genera.

Redefining Phrymaceae: the placement of Mimulus, tribe Mimuleae, and Phryma.

In light of the molecular evidence, it is clear that species of Phrymaceae have undergone two geographically distinct radiations; one in western North America and another in Australia (about 30 species).

Floral anatomy of Thomandersia (Lamiales), with particular reference to the nature of the retinaculum and extranuptial nectaries

It is found that Thomandersia shares a range of characters with each of the families to which it might be sister-group, and that some of these primary homologies must therefore be homoplastic.

The Linderniaceae and Gratiolaceae are further lineages distinct from the Scrophulariaceae (Lamiales).

The Lamiales are one of the largest orders of angiosperms, with about 22,000 species. The Scrophulariaceae, as one of their most important families, has recently been shown to be polyphyletic. As a

Phylogenetics of amaranthaceae based on matK/trnK sequence data-evidence from parsimony, likelihood, and bayesian analyses

Amaranthaceae and Chenopodiaceae together represent the most species-rich monophyletic group in the angiosperm order Caryophyllales and the complex stellate pore ornamentation was reconstructed as having evolved at least twice in parallel.
