Phylogenetic relationships in Apocynaceae based on nuclear PHYA and plastid trnL-F sequences, with a focus on tribal relationships

Caryologia, 2019
To date, most molecular phylogenetic studies of Apocynaceae have been based on plastid DNA regions or nuclear ribosomal DNA. In this study, we used part of the PHYA (phytochrome A) exon, a low-copy nuclear gene, and combined it with the trnL-F region ...

Evolution of pyrrolizidine alkaloid biosynthesis in Apocynaceae: revisiting the defence de-escalation hypothesis. [PDF]

New Phytol, 2018
Summary Plants produce specialized metabolites for their defence. However, specialist herbivores adapt to these compounds and use them for their own benefit. Plants attacked predominantly by specialists may be under selection to reduce or eliminate production of co‐opted chemicals: the defence de‐escalation hypothesis.

Homospermidine synthase evolution and the origin(s) of pyrrolizidine alkaloids in Apocynaceae. [PDF]

Am J Bot
Abstract Premise Enzymes that are encoded by paralogous genes and produce identical specialized metabolites in distantly related plant lineages are strong evidence of parallel phenotypic evolution. Inference of phenotypic homology for metabolites produced by orthologous genes is less straightforward, since orthologs may be recruited in parallel into ...

Apocynaceae wood evolution matches key morphological innovations. [PDF]

Am J Bot
Abstract Premise This paper provides an overview of the wood anatomy of the dogbane family (Apocynaceae), reconstructs wood anatomical trait evolution, and links this evolution with woody growth‐form transitions and floral and seed trait innovations across the family.

A new species of Mandevilla (Apocynaceae) from limestone outcrops in Central Brazil with a short note on the occurrence of geophytes in rauvolfioids and apocynoids

Acta Botânica Brasílica, 2023
Mandevilla calcicola, endemic to limestone formations in Goiás state, Brazil, is described. A key and photos for all Mandevilla species reported in Goiás and Distrito Federal, Brazil, are included.

Increasing the known floristic diversity of Brazilian inselbergs: two new species of Mandevilla (Apocynaceae) from Espírito Santo [PDF]

Acta Botânica Brasílica, 2019
Two new species of Mandevilla endemic to inselbergs of the state of Espírito Santo, Brazil, are described. Mandevilla alata resembles M. callista but differs by having winged stems, shorter petioles, shorter pedicels, and a white corolla with a red ...

Settling a family feud: a high‐level phylogenomic framework for the Gentianales based on 353 nuclear genes and partial plastomes

American Journal of Botany, Volume 108, Issue 7, Page 1143-1165, July 2021., 2021
Premise Comprising five families that vastly differ in species richness—ranging from Gelsemiaceae with 13 species to the Rubiaceae with 13,775 species—members of the Gentianales are often among the most species‐rich and abundant plants in tropical forests. Despite considerable phylogenetic work within particular families and genera, several alternative

, 2015
In order to test the monophyly of Mandevilla Lindl., the largest genus in tribe Mesechiteea (Apocynaceae, Apocynoideae). and its affinities to other genera, in the tribe.
