Slide1
Approach Set up 10 common gardens spanning climate zones across eight states and 1,100 miles, each containing a propagated panel of 732 switchgrass genotypes.Sequence, assemble, and annotate the switchgrass genome.Analyze biomass and survival among genotypes for climate–gene–biomass associations.
Nationwide collaboration unlocks switchgrass genome
BRC Science Highlight
GLBRC February 2021
Geographic distribution of common gardens and plant collection locations, and spatial distribution models of each ecotype. The ecotype color legend accompanies the representative images of each ecotype to the right of the map.
Objective
Produce a high-quality reference sequence of the complex switchgrass genome
All four BRCs have expanded the network of common gardens and are exploring improvements to switchgrass through more targeted genome editing techniques to improve crop traits and customize the crop for additional end products.
Result/Impacts
The
reference genome will provide breeders with the necessary tools to increase switchgrass yield for the sustainable production of bioenergy.
