Project description:Aegilops tauschii is the donor of the wheat D subgenome and an important genetic resource for wheat. The assembly of Ae. tauschii acc. AL8/78 reference genome sequence Aet v4.0 was therefore an important milestone for wheat biology and breeding. The combination of the > 4.2 Gb size of the Ae. tauschii genome and > 84% of recently evolved repeated sequences make sequencing this genome challenging. Here, we report further advances in the development of the Ae. tauschii acc. AL8/78 genome sequence. Two new genome-wide optical maps were constructed and employed in the revision of pseudomolecules and estimations of gap lengths. Gaps were closed with contigs of single-molecule Pacific Biosciences reads. The number of gaps in Aet v5.0 decreased by 38,899 compared to Aet v4.0. Transposable elements and protein-coding genes were reannotated. The number of high-confidence genes was reduced from 38,886 in Aet v4.0 to 32,980 in Aet v5.0. A nonredundant set of 478 biologically important genes including many of known function in wheat was manually annotated. Sixty-one microRNA precursor and 60 phasiRNA loci were discovered, annotated, and their expression was characterized. Also characterized was expression of other small RNAs, such as hc-siRNAs and tRFs. This upgraded genome sequence will facilitate the use of Ae. tauschii in wheat breeding and biological research.

Project description:We profiled genome-wide gene expression changes in newly hybridized triploids (ABD), its genome-duplicated hexaploid (AABBDD), stable synthetic hexaploid (AABBDD) and T. turgidum (AABB) and Ae. tauschii (DD) parental lines of two independent crosses to reconstruct the events of allopolyploidization and genome stabilization. Gene expression levels of newly hybridized triploids (ABD), its chromosome-doubled hexaploids (AABBDD), stable synthetic hexaploid (AABBDD) which were selfed during 4 and 13 generations, and their parents, Triticum turgidum (AABB) and Aegilops tauschii (DD) were compared. Total RNA of each line was extracted from three biological replicates of two leaves seedlings except for triploids.For newly hybridized triploids, biological duplicates of two leaves seedlings were used.
