Triticeae is a large and important tribe in the grass family Poaceae, including staple food and feed crops such as wheat, rye, barley, and forage crops such as Chinese wild-rye. In the last decade, genome sequencing of the five genuses, including Aegilops, Triticum, Hordeum, Secale, Thinopyrum brought Triticeae study to a new era: Genomics Triticeae. However, many important Triticeae genuses have not been sequenced; the assembling quality was not satisfied; the genome annotation was carried out separately with different standards; and a comparative analysis across the whole Triticeae tribe was not integrated. Here, we analyzed more than 30 genomes from 20 species of ten triticeae genuses, including Aegilops, Dasypyrum, Elymus, Hordeum, Lemus, Psasrostachys, Pseudoroegneria, Secale, Thinopyrum and Triticum. The assembling quality was improved significantly; the contig N50 length reached more than 100 Mb. We summarized our results in the following five aspects: (1) annotation of gene and TE in a unified standard; (2) establishment of Triticeae pan-genome; (3) analysis of the gene family expansion and contraction and their function; (4) phylogeny and evolution analysis and finally (5) accelerations of the Triticeae genomics to wheat improvement. We believe these results will be valuable resources for the whole wheat communities.
