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

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 ...
