Global genomic population structure of wild and cultivated oat reveals signatures of chromosome rearrangements Open
The genus Avena consists of approximately 30 wild and cultivated oat species. Cultivated oat is an important food crop, yet the broader genetic diversity within the Avena gene pool remains underexplored and underexploited. Here, we charact…

A pangenome and pantranscriptome of hexaploid oat Open
Oat grain is a traditional human food rich in dietary fiber that contributes to improved human health. Interest in the crop has surged in recent years owing to its use as the basis for plant-based milk analogs. Oat is an allohexaploid with…

A uniform gene and chromosome nomenclature system for oat (Avena spp.) Open
Context Several high-quality reference genomes for oat (Avena sativa L. and relatives) have been published, with the prospect of many additional whole-genome assemblies emerging in the near future. Aims This has necessitated an effort by t…

Genotype and Environment Affect the Grain Quality and Yield of Winter Oats (Avena sativa L.) Open
The extent to which the quality and yield of plant varieties are influenced by the environment is important for their successful uptake by end users particularly as climatic fluctuations are resulting in environments that are highly variab…

The genome assembly and gene annotation of oat. Open
The data include a summary of the genome assembly and annotation of oat. Chromosome-level genome assembly and scaffold-level genome assembly are both can be found in this dataset. Genome annotation files are provided in .fa file, .gff3 fil…

Analysis of Two New Arabinosyltransferases Belonging to the Carbohydrate-Active Enzyme (CAZY) Glycosyl Transferase Family1 Provides Insights into Disease Resistance and Sugar Donor Specificity Open
Glycosylation of small molecules is critical for numerous biological processes in plants, including hormone homeostasis, neutralization of xenobiotics, and synthesis and storage of specialized metabolites. Glycosylation of plant natural pr…

Detached Leaf Assays for Resistance to Crown Rust Reveal Diversity Within Populations of <i>Avena sterilis</i> Open
Crown rust is the most widespread and damaging disease of oat (Avena species). Genetic resistance to the pathogen is the preferred method for crop protection but widespread deployment of limited numbers of major effect genes has promoted t…

Towards take‐all control: a C‐21β oxidase required for acylation of triterpene defence compounds in oat Open
Summary Oats produce avenacins, antifungal triterpenes that are synthesized in the roots and provide protection against take‐all and other soilborne diseases. Avenacins are acylated at the carbon‐21 position of the triterpene scaffold, a m…

Multi-Environmental Trials Reveal Genetic Plasticity of Oat Agronomic Traits Associated With Climate Variable Changes Open
Although oat cultivation around the Mediterranean basin is steadily increasing, its yield in these regions lags far behind those of Northern Europe. This results mainly from the poor adaptation of current oat cultivars to Mediterranean env…

High-density marker profiling confirms ancestral genomes of Avena species and identifies D-genome chromosomes of hexaploid oat Open
Genome analysis of 27 oat species identifies ancestral groups, delineates the D genome, and identifies ancestral origin of 21 mapped chromosomes in hexaploid oat. We investigated genomic relationships among 27 species of the genus Avena us…

A Consensus Map in Cultivated Hexaploid Oat Reveals Conserved Grass Synteny with Substantial Subgenome Rearrangement Open
Hexaploid oat ( Avena sativa L., 2 n = 6 x = 42) is a member of the Poaceae family and has a large genome (∼12.5 Gb) containing 21 chromosome pairs from three ancestral genomes. Physical rearrangements among parental genomes have hindered …
