Interpretive Summary: Shifting our grain crop life cycle from annual to perennial would result in a new form of agriculture that is more environmentally friendly and resilient to climate change, but this has proven to be a challenging goal. On the one hand, efforts to breed perenniality into an annual grain crop such as wheat have so far not been fully successful. On the other hand, efforts to rapidly domesticate perennial grasses such as Thinopyrum intermedium have encountered significant hurdles even though it is closely related to wheat. The recent release of the genome sequence of T. intermedium reveals that many wheat domestication genes are highly conserved in T. intermedium. This suggests a road map for directed accelerated domestication of this plant by the help of molecular tools.
