The banana (Musa acuminata) genome and the evolution of monocotyledonous plants
This first monocotyledon high-continuity whole-genome sequence reported outside Poales represents an essential bridge for comparative genome analysis in plants and clarifies commelinid-monocotYledon phylogenetic relationships, reveals Poaceae-specific features and has led to the discovery of conserved non-coding sequences predating monocotinoid–eudicotylingon divergence.
The pineapple genome and the evolution of CAM photosynthesis
The pineapple lineage has transitioned from C3 photosynthesis to CAM, with CAM-related genes exhibiting a diel expression pattern in photosynthetic tissues, providing the first cis-regulatory link between CAM and circadian clock regulation.
Allopolyploidy, diversification, and the Miocene grassland expansion
It is found that genome duplication has occurred at a remarkable rate, accounting for at least a third of all speciation events in a group of about 1,200 species, focusing here on the grass tribe Andropogoneae, an economically and ecologically important group of C4 species with a high frequency of polyploids.
A genome triplication associated with early diversification of the core eudicots
The rapid radiation of core eudicot lineages that gave rise to nearly 75% of angiosperm species appears to have occurred coincidentally or shortly following the gamma triplication event.
Multiple polyploidy events in the early radiation of nodulating and nonnodulating legumes.
The timing of duplications in the gene trees indicates that the papilionoid WGD occurred in the common ancestor of all papilionoids, and there is evidence for several independent WGDs near the base of other major legume lineages, including the Mimosoideae-Cassiinae-Caesalpinieae (MCC), Detarieae, and Cercideae clades.
Origin and evolution of the octoploid strawberry genome
A near-complete chromosome-scale assembly for cultivated octoploid strawberry (Fragaria × ananassa) is reported and the origin and evolutionary processes that shaped this complex allopolyploid are uncovered, providing a useful resource for genome-wide analyses and molecular breeding.

It is found that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns.
Assembling the Tree of the Monocotyledons: Plastome Sequence Phylogeny and Evolution of Poales1
The results of an initial project by the Monocot AToL (Angiosperm Tree of Life) team on phylogeny and evolution in Poales are presented, using sequence data for 81 plastid genes from 83 species of angiosperms and recovered highly concordant relationships using maximum likelihood (ML) and maximum parsimony (MP).
Diversification times among Brassica (Brassicaceae) crops suggest hybrid formation after 20 million years of divergence.

Evidence is found that the tribe Brassiceae originated around the intersection forming between the Arabian Peninsula and Saharan Africa approximately 24 million years ago (Mya), and the maternal genomes of the three diploid crop Brassicas are not closely related, which challenges previous hypotheses about the biogeographic origins.
A Phylogenomic Assessment of Ancient Polyploidy and Genome Evolution across the Poales
Improved resolution of the timing of WGD events in monocot history provides evidence for the influence of polyploidization on functional evolution and species diversification.
