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...

Intermediate wheatgrass [IWG; Thinopyrum intermedium (Host) Barkworth & D.R. Dewey] is a perennial cereal and forage crop marketed for its grain, Kernza. Lodging, which correlated with plant height, can reduce IWG grain yield. Our goal was to determine the effects of growth regulator trinexapac-ethyl (TE) application rate; harvest timing; N rate on lodging, aboveground biomass, yield, index. Th...

Wheat streak mosaic virus (WSMV) is a mite-vectored with substantial economic impact on wheat production. One of the effective sources resistance to WSMV, Wsm1, carried translocation from Thinopyrum intermedium. The original whole arm form this (T4DL·4JsS) was highly against WSMV but yield penalty in absence virus. Shorter recombinants Th. intermedium are now available. This study characterized...

AimsPerennial crops with more extensive and deep root systems could access stored water build resilience to shortage. In the context of human nutrition, perennial grain are very interesting. However, it is still questionable whether they effective in using subsoil water. We compared intermediate wheatgrass (Kernza®) Thinopyrum intermedium, a crop, alfalfa Medicago sativa, forage for growth upta...

The development of perennial grain crops is driven by the vision simultaneous food production and enhanced ecosystem services. Typically, like intermediate wheatgrass (IWG)[Thinopyrum intermedium (Host) Barkworth & D.R Dewey] have low seed yield other detrimental traits. Next-generation sequencing has made genomic selection (GS) a tractable viable breeding method. To investigate how an IWG prog...

There is considerable variability in salt tolerance amongst members of the Triticeae, with the tribe even containing a number of halophytes. This is a review of what is known of the differences in salt tolerance of selected species in this tribe of grasses, and the potential to use wild species to improve salt tolerance in wheat. Most investigators have concentrated on differences in ion accumu...

Recent molecular phylogenetic studies of polyploid plants have successfully clarified complex patterns of reticulate evolution. In this study of Elymus repens, an allohexaploid member of the wheat tribe Triticeae, chloroplast and nuclear DNA data reveal an extreme reticulate pattern, revealing at least five distinct gene lineages coexisting within the species, acquired through a possible combin...
