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 ...

A fishing expedition to discover the pollinators of several subtropical Apocynaceae. [PDF]

Appl Plant Sci, 2020
Premise Flowers of the Apocynaceae (milkweed family) have complex structures and pollination mechanisms. Pollen removal and deposition in Angadenia, Pentalinon, and Echites are similar, with anthers releasing pollen onto the sterile style head. The mid‐style head excretes a glue that coats the mouthparts of vistors to aid in the transfer of pollen ...

Enabling evolutionary studies at multiple scales in Apocynaceae through Hyb-Seq. [PDF]

Appl Plant Sci, 2020
Premise Apocynaceae is the 10th largest flowering plant family and a focus for study of plant–insect interactions, especially as mediated by secondary metabolites. However, it has few genomic resources relative to its size. Target capture sequencing is a powerful approach for genome reduction that facilitates studies requiring data from the nuclear ...

Echiteae

, 2021
2.6. Echiteae, Odontadenieae, Mesechiteae These three tribes form a well-supported monophyletic clade of predominantly New World genera (Fishbein et al., 2018), but the boundaries among them have been redrawn several times (Morales et al., 2017; Sim ...

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.

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.
