Barley Genetics Newsletter v49 (2019-2020) is available at GrainGenes at https://wheat.pw.usda.gov/ggpages/bgn/.

In 2020, we lost both Phil Bregitzer and Udda Lundqvist, Editors of BGN, and we will miss them greatly. Many thanks to Jerry Franckowiak and Victoria Blake for the completion of this issue.

The following gene class has been added to GrainGenes, based on the information in the Wheat Gene Catalogue (WGC). This includes all genes, along with any associated alleles, references, loci and germplasm sources:

Many new mapping sets for oat have been added to the GrainGenes collection of genetic maps. Many thanks to Charlene Wight at AAFC for precurating these map sets.

Following the publication of the Wheat 10+ Genomes Project at Nature, GrainGenes is releasing genome browsers and BLASTable database for the the reference quality genome assemblies.

You can find the 10 genome browsers here (under Wheat/ 10+ Wheat Genome Project): https://wheat.pw.usda.gov/GG3/genome_browser

You can reach the BLAST tool here: https://wheat.pw.usda.gov/blast

Five new mapping sets for oat have been added to the GrainGenes collection of genetic maps. Many thanks to Charlene Wight at AAFC for precurating these map sets.

The following gene class has been added to GrainGenes, based on the information in the Wheat Gene Catalogue (WGC). This includes all genes, along with any associated alleles, references, loci, germplasm sources:
Frost tolerance or resistance is the ability of a plant to survive freezing temperatures, and is an important part of winter hardiness. A lack of frost resistance is considered as a major factor limiting cultivation of winter wheat (Wurschum et al., 2017).

Pc53 for resistance to Puccinia coronata (crown rust) was mapped in two oat populations by Admassu-Yimer el al. (2018) Mapping of crown rust resistance gene Pc53 in oat (Avena sativa), PLoS ONE 13(12):e0209105

See Oat-2018-Pc53 mapping data for links to the maps.

For all recent oat genetic maps added to GrainGenes, see the Oat Mapathon Progress page.

Nine QTL from Montilla-Bascon et al (2015) were mapped to DArT and SSR markers in a GWAS analysis of 177 Spanish oat cultivars and landraces. These include five for adult resistance to crown rust, three for adult resistance to powdery mildew and one for seedling powdery mildew resistance.

MNase chromatin states tracks are available at GrainGenes IWGSC Chinese Spring v1.0 genome browser based on the data provided by the Akhunov Lab.

MNase-sensitive and MNase-resistant footprint data, as well as their intersects against 1,000 wheat genomes are available at the GrainGenes IWGSC Chinese Spring genome browser.
