    Abstract:

    Triticeae crops mainly include common wheat, barley, rye, oat and Triticale etc. These species usually host a complex genome with huge size (>5.1Gb, with >80% repetitive elements), thus resulting in establishment of high-quality genome reference behind other cereal crops such as rice and maize. Taking advantage of achievement on sequencing methodologies along with dramatic decrease on the sequence cost, studies of the Triticeae genomics have become reasonable, and breakthroughs in population genetics, pangenomics, and epigenomics have been made. These achievements enabled better understanding of the genomic variation and selection, and also provided resources to decipher the origin, domestication and local adaptation as well as assist genetic improvement of modern varieties. This mini-review summarizes current status and research trends in the Triticeae genomics in the past few years, and proposes the hotspots in post-genomics era in Triticeae crops.
