Open AccessLow impact of polyploidization on the transcriptome of synthetic allohexaploid wheat
Bread wheat is a recent allohexaploid (genomic constitution AABBDD) that emerged through a hybridization between tetraploid Triticum turgidum (AABB) and diploid Aegilops tauschii (DD) less than 10,000 years ago. ...

Tracing the ancestry of modern bread wheats
For more than 10,000 years, the selection of plant and animal traits that are better tailored for human use has shaped the development of civilizations. During this period, bread wheat (Triticum aestivum) emerged...

Open AccessPaleogenomics: reconstruction of plant evolutionary trajectories from modern and ancient DNA
How contemporary plant genomes originated and evolved is a fascinating question. One approach uses reference genomes from extant species to reconstruct the sequence and structure of their common ancestors over...

Reconstructing the genome of the most recent common ancestor of flowering plants
Jérôme Salse and colleagues report a reconstruction of the most recent common ancestor of modern monocots and eudicots, which dates to the late Triassic era. Their results represent a resource for plant geneti...

Open AccessPaleo-evolutionary plasticity of plant disease resistance genes
The recent access to a large set of genome sequences, combined with a robust evolutionary scenario of modern monocot (i.e. grasses) and eudicot (i.e. rosids) species from their founder ancestors, offered the oppo...

Open AccessDeciphering the genomic structure, function and evolution of carotenogenesis related phytoene synthases in grasses
Carotenoids are isoprenoid pigments, essential for photosynthesis and photoprotection in plants. The enzyme phytoene synthase (PSY) plays an essential role in mediating condensation of two geranylgeranyl dipho...

Open AccessRNA-seq in grain unveils fate of neo- and paleopolyploidization events in bread wheat (Triticum aestivum L.)
Whole genome duplication is a common evolutionary event in plants. Bread wheat (Triticum aestivum L.) is a good model to investigate the impact of paleo- and neoduplications on the organization and function of mo...

Combined meta-genomics analyses unravel candidate genes for the grain dietary fiber content in bread wheat (Triticum aestivum L.)
Grain dietary fiber content in wheat not only affects its end use and technological properties including milling, baking and animal feed but is also of great importance for health benefits. In this study, inte...

Genomics in cereals: from genome-wide conserved orthologous set (COS) sequences to candidate genes for trait dissection
Recent updates in comparative genomics among cereals have provided the opportunity to identify conserved orthologous set (COS) DNA sequences for cross-genome map-based cloning of candidate genes underpinning q...

Open AccessNew insights into the origin of the B genome of hexaploid wheat: Evolutionary relationships at the SPA genomic region with the S genome of the diploid relative Aegilops speltoides
Several studies suggested that the diploid ancestor of the B genome of tetraploid and hexaploid wheat species belongs to the Sitopsis section, having Aegilops speltoides (SS, 2n = 14) as the closest identified re...

Single nucleotide polymorphism, genetic map**, and expression of genes coding for the DOF wheat prolamin-box binding factor
Wheat prolamin-box binding factor (WPBF) was shown to be an activator of Triticum aestivum L. storage protein genes. Three homoeologous genes encoding this transcription factor were isolated from a bacterial arti...
