Phylogenomics and adaptive evolution of hydrophytic umbellifers (tribe Oenantheae, Apioideae) revealed from chloroplast genomes.

ABSTRACT:

Background

Tribe Oenantheae consists mainly of aquatic species within the Apioideae. The unique morphology and habitat distinguish this group from other Apioideae groups. However, the genomic information of these group species has not been widely developed, and the molecular mechanisms of adaptive evolution remain unclear.

Results

We provide comparative analyses on 30 chloroplast genomes of this tribe representing five genera to explore the molecular variation response to plant adaptations. The Oenantheae chloroplast genomes presented typical quadripartite structures, with sizes ranging from 153,024 bp to 155,006 bp. Gene content and order were highly conserved with no significant expansion or contraction observed. Seven regions (rps16 intron-trnK, rpoB-trnC, trnE-trnT-psbD,
