The findings indicate the possibility that hexaploid E. crus-galli may have originated from a tetraploid Echinochloa species other than E. oryzicola, and revealed that ninja possesses a distinct genomic composition, while showing close relationships to E. oryzicola in both its chloroplast and nuclear genomes.
BACKGROUND AND AIMS
Polyploidization is one of the major evolutionary forces in grasses (Poaceae), yet the genomic relationships between polyploid species across different continents remain poorly understood. Here, we aim to determine whether phylogenetically distinct South American allohexaploid fescues, Festuca uloch...

The results indicate that while the Ormosia plastomes retain the typical angiosperm quadripartite structure, they show a substantial expansion of the inverted repeat (IR) regions compared to the sister lineage of core genistoids (represented by Lupinus and Sophora), with the boundaries extending to the clpP gene.

Br Brachypodium hybridum exemplifies how recurrent allopolyploidization, minimal subgenomic recombination, and environmental filtering generate and maintain genetic diversity, establishing it as a model for polyploid evolution and ecological adaptation in grasses worldwide.

While interspecific hybridization is a recognized key driver of plant diversification in recently diverged lineages, the resulting introgression can generate complex patterns of genetic and morphological variation that often challenge the recognition of species boundaries. In

The recognition of Allium erimomeli as a distinct species emphasizes the significance of polyploidy and insular isolation in the diversification of A. Codonoprasum in the Aegean region and enhances the understanding of evolutionary relationships within the section.

The genus Inula (Asteraceae) includes numerous medicinally important species, but phylogenetic relationships within the Inula complex remain difficult to resolve using morphological characters alone. In this study, we assembled and annotated the complete chloroplast genome of Inula grandis using Illumina paired-end seq...
