We investigated the variation in plant response in host-pathogen interactions between wild (Aegilops spp., Triticum spp.) and domesticated wheat (Triticum spp.) and Wheat dwarf virus (WDV). The distribution of WDV and its wild host species overlaps in Western Asia in the Fertile Crescent, suggesting a coevolutionary relationship. Bread wheat originates from a natural hybridization between wild ...

Aegilops tauschii Coss. is known as a noxious grass weed seriously affecting wheat quality and yield. To investigate its present occurrence in fields the potential genetic diversity of China, filed survey covering major production regions was conducted during 2017–2019. Seeds different Ae. populations collected from were analyzed with Simple Sequence Repeats (SSRs) technique. Results showed tha...

Gametocidal (Gc) chromosomes can ensure their preferential transmission by killing the gametes without themselves through causing chromosome breakage and therefore have been exploited as an effective tool for genetic breeding. However, to date very little is known about the molecular mechanism of Gc action. In this study, we used methylation-sensitive amplified polymorphism (MSAP) technique to ...

Leaf rust is one of the most devastating wheat diseases worldwide, to which many resistance genes have been successfully introgressed from wild relatives. Though Thinopyrum ponticum-derived leaf gene Lr19 widely effective, and previous studies shown its likely presence in Aegilops tauschii, no thorough investigation has conducted confirm this. The current study examined Ae. tauschii using molec...

To produce a good F1 hybrid variety wheat crop, it is necessary to explore novel cytoplasmic male sterility (CMS) lines and their maintainer line. This study aimed to identify cytoplasmic variation in three isonuclear-alloplasmic male sterile lines Aegilops kotschyi (Ae.kots) -90-110, Aegilops ventricosa (Ae.ven) -90-110, and Triticum spelta (T.spelta) -90-110 and their maintainer line, A-90-11...

Transcription factors (TFs) play important roles in plant growth, development, and responses to environmental stress. In this study, we collected 1,455 full-length (FL) cDNAs of TFs, representing 45 families, from wheat and its relatives Triticum urartu, Aegilops speltoides, Aegilops tauschii, Triticum carthlicum, and Triticum aestivum. More than 15,000 T0 TF FOX (Full-length cDNA Over-eXpressi...

44 Effects of polyploidy in allohexaploid wheat (Triticum aestivum L.) have primarily been ascribed 45 to increases in coding sequence variation and potential to acquire new gene functions through 46 mutation of redundant loci. However, regulatory variation that arises through new promoter and 47 transcription factor combinations or epigenetic events may also contribute to the effects of 48 pol...

Nascent allohexaploid wheat may represent the initial genetic state of common wheat (Triticum aestivum), which arose as a hybrid between Triticum turgidum (AABB) and Aegilops tauschii (DD) and by chromosome doubling and outcompeted its parents in growth vigor and adaptability. To better understand the molecular basis for this success, we performed mRNA and small RNA transcriptome analyses in na...
