Although extremely challenging, with the ongoing efforts from related research community, switchgrass whole genome sequencing could be expected to bear fruits in a foreseeable future. The availability of a completed reference genome of switchgrass is of great importance, which would not only facilitate a better understanding of critical biological pathways for complex traits such as biomass production and efficient bioconversion in this bioenergy crop, but also accelerate development of novel genomics, genetics and molecular tools for switchgrass feedstock improvement through conventional and molecular breeding for its cost-effect use for biofuel production. As the extant and emerging genomic tools for switchgrass unfold, a more robust molecular foundation will present opportunities for accelerated breeding and new cultivar development ushering switchgrass genetics and genomics into a new era of bioenergy crop development.
