Insights into phylogeny, age and evolution of Allium (Amaryllidaceae) based on the whole plastome sequences.

ABSTRACT:

Background and aims

The genus Allium L., one of the largest monocotyledonous genera and one that includes many economically important crops with nutritional and medicinal value, has been the focus of classification or phylogeny studies for centuries. Recent studies suggested that the genus can be divided into 15 subgenera and 72 sections, which were further classified into three evolutionary lineages. However, the phylogenetic relationships reconstructed by one or two loci showed weaker support, especially for the third evolutionary lineage, which might not show the species relationships very clearly and could hinder further adaptive and evolutionary study.

Methods

In this study, a total of 39 complete chloroplast genomes of Allium (covering 12 Allium subgenera) were collect
