A transcriptome-based study on the phylogeny and evolution of the taxonomically controversial subfamily Apioideae (Apiaceae).

ABSTRACT:

Background and aims

A long-standing controversy in the subfamily Apioideae concerns relationships among the major lineages, which has prevented a comprehensive study of their fruits and evolutionary history. Here we use single copy genes (SCGs) generated from transcriptome datasets to generate a reliable species tree and explore the evolutionary history of Apioideae.

Methods

In total, 3351 SCGs were generated from 27 transcriptome datasets and one genome, and further used for phylogenetic analysis using coalescent-based methods. Fruit morphology and anatomy were studied in combination with the species tree. Eleven SCGs were screened out for dating analysis with two fossils selected for calibration.

Key results

A well-supported species tree was generated with a topolog
