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 ...

American Journal of Botany, Volume 105, Issue 3, Page 495-513, March 2018., 2018 Premise of the Study We provide the largest phylogenetic analyses to date of Apocynaceae in terms of taxa and molecular data as a framework for analyzing the evolution of vegetative and reproductive traits. Methods We produced maximum‐likelihood phylogenies of Apocynaceae using 21 plastid loci sampled from 1045 species (nearly 25% of the family) and ...

International Journal of Biodiversity, Volume 2015, Issue 1, 2015., 2015 Loss of phylogenetic diversity (PD) has gained increasing attention in conservation biology. However, PD is not equally distributed in a phylogeny and can be better assessed when species relatedness (phylogenetic structure: PS) is also considered. Here, we investigate PD and PS in two refuges of biodiversity in northeastern Brazil: the Bahia Costal ...

A revised classification of the Apocynaceae s.l. [PDF]
, 2000 The Asclepiadaceae, as traditionally defined, have repeatedly been shown to be an apomorphic derivative of the Apocynaceae. It has often been recommended that the Asclepiadaceae be subsumed within the Apocynaceae in order to make the latter monophyletic.

Wood anatomy of Rauvolfioideae (Apocynaceae): a search for meaningful non‐DNA characters at the tribal level [PDF]
American Journal of Botany, 2008 Wood anatomical studies in the economically important Apocynaceae or dogbane family are fragmentary. This study represents a first attempt to unravel the phylogenetic significance and major evolutionary trends in the wood of the family, using existing and new microscopic wood observations within the large subfamily Rauvolfioideae.

Reestablishment, new records, and a key for the species of Aspidosperma (Apocynaceae) from the Brazilian Amazon [PDF]
, 2019 As a result of systematic study of the Neotropical genus Aspidosperma (Apocynaceae), we reestablish the species A. centrale and A. duckei, and report A. steinbachii and A. tambopatense as new records for Brazil. We provide taxonomic descriptions of these
