Leaf rust is an important disease, threatening wheat production annually. Identification of resistance genes or QTLs for effective field could greatly enhance our ability to breed durably resistant varieties. We applied a genome wide association study (GWAS) approach identify in 338 spring breeding lines from public and private sectors that were predominately developed the Americas. A total 46 identified seedling traits approximately 20–30 confer varying degrees. The 10 accounting most...
Leaf rust (caused by Erikss. []) is increasingly impacting durum wheat ( L. var. ) production with the recent appearance of races virulence to widely grown cultivars in many producing areas worldwide. A highly virulent race on was recently detected Kansas. This may spread northern Great Plains, where most US produced. The objective this study identify sources resistance several from United States and Mexico at seedling stage greenhouse adult field experiments. Genome-wide association (GWAS)...
Silphium perfoliatum L. (cup plant, silphie) and S. integrifolium Michx. (rosinweed, silflower) are in the same subfamily tribe as sunflower ( Helianthus annuus L.). has been grown many countries a forage or bioenergy crop with quality approaching that of alfalfa Medicago sativa L.) biomass yield close to maize Zea mays some environments. large seeds taste oil similar traditional oilseed sunflower. species all long‐lived, diploid perennials. Crops from this genus could improve stability,...
A network of 21 experiments was established across nine countries on four continents and spanning both hemispheres, to evaluate the relative performance early generation perennial cereal material derived from wheat, rye, barley inform future breeding strategies. The experimental lines were grown in replicated single rows, first year production phenology characteristics as well yield persistence for up three years monitored. study showed that existing is all relatively short-lived (≤3 years),...
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version oilseed sunflower, its close relative. Grain crops with deep root systems will provide farmers new alternatives for managing soil moisture and limiting or remediating erosion, fertilizer leaching, loss biota. Several cycles selection increased seed production potential following initial germplasm evaluation 2002 have provided opportunities to document botany ecology this relatively...
ABSTRACT Perennial wheatgrasses ( Thinopyrum spp.) are recognized sources of genetic variation for annual wheat Triticum aestivum L.) improvement. Amphiploid lines made by crossing spp. and T. (common wheat) can increase resilience to pathogens abiotic stress. However, lack pairing between chromosomes species reduces genome stability, seed set, perenniality. Fifty‐two wheat–wheatgrass amphiploids from the perennials intermedium (Host) Barkworth & D. R. Dewey, ponticum (Podp.) junceum...
Abstract Empirical evidence of the influence climate on plant–pathogen coevolution is limited but crucial to understand, as anthropogenic pressures including fragmentation and change threaten biodiversity. In this study, we tested patterns using Silphium integrifolium Michx., a native tallgrass prairie species that undergoing domestication, its foliar pathogens. We collected seeds from four remnants each three regions along an east–west precipitation gradient in central North America used...
‘Jagger’ has been used widely as a parent to develop hard red winter wheat ( Triticum aestivum L.) varieties throughout the US southern Great Plains. Jagger resistance stem rust pathogen race TTTTF, which is virulent many cultivars, yet genetic basis of this was unknown. Marker analysis and leaf stripe demonstrated that 2NS/2AS translocation from T. ventricosum (Tausch) Ces., Pass. & Gilelli. This segment contains genes Sr38 , Lr37 Yr17 . Stem infection types on Jagger, however,...
New crops with greater capacity for delivering ecosystem services are needed to increase agricultural sustainability. However, even in these crops, seed yield is usually the main criteria grain domestication. This focus on can cause unintended structural and functional changes. Leaves of selected plants tend be more vulnerable infection, which reduce performance, assimilates, ultimately yield. Our objectives were determine impact rust (caused by Puccinia silphii) leaf function Silphium...
Intermediate wheatgrass (IWG, Thinopyrum intermedium, (Host) Barkworth & D.R. Dewey subsp. 2n = 6x 42) is a novel perennial crop currently undergoing domestication efforts. It offers remarkable ecosystem services and yields higher relative to other grain crops. While IWG mostly resistant Fusarium head blight (FHB), identifying genomic regions associated with resistance will help protect the from potential disease epidemics. An biparental population of 108 individuals was developed by...
A previous genome-wide association study (GWAS) for leaf rust (caused by Puccinia triticina) resistance identified 46 quantitative trait loci (QTL) in an elite spring wheat diversity panel. With the aim of characterizing pleiotropic sources to both and stripe P. striiformis f. sp. tritici), responses were tested five U.S. environments at adult-plant stage races seedling stage. The data revealed balanced phenotypic distributions this population except response tritici race PSTv-37. GWAS...
Two PCR-based assays were examined for tracing the presence of a Thinopyrum chromosome segment (Tc6 or Tc14) conferring barley yellow dwarf virus (BYDV) resistance in wheat breeding lines. The microsatellite gwm37 was used to assay its wheat, Group 7, homoeologous segment, and effective characterising breeders material since heterozygous lines could be identified. A new set primers derived from Thinopyrum-specific DNA (csTiB1) provided dominant marker that readily scored by agarose gel...
Perennial grains have been proposed as a soil-healthy alternative to annual grains. Intermediate wheatgrass (Thinopyrum intermedium), whose seed is currently sold under the trade name Kernza®, and silflower (Silphium integrifolium), which in early stages of domestication at The Land Institute Central Kansas, lack characterization for their deficiency symptoms. This has complicated attempts assess causes visible stress on plants field greenhouse. By growing Th. intermedium S. integrifolium...
Dahlia common mosaic virus (DCMV) was previously reported to infect only dahlias ( variabilis). However, DCMV identified for the first time in association with Silphium spp. The complete genome of cloned and sequenced from naturally occurring symptomatic silphium plants grown Kansas. two isolates showed over 98% sequence identity those dahlia D. variabilis endogenous pararetroviral (DvEPRS) also detected all 19 samples tested this study, suggesting that DvEPRS may exist as an integrated...
Abstract Intracellular plant defense against pathogens is mediated by a class of disease resistance genes known as NB‐LRRs or NLRs (R genes). Many the diseases these protect are more prevalent in regions higher rainfall, which provide better growth conditions for pathogens. As such, we expect selective pressure maintenance and proliferation R plants adapted to wetter conditions. In this study, enriched libraries using RenSeq from baits primarily developed common sunflower ( Helianthus annuus...

The majority of domesticated plant species are herbaceous annuals and woody perennials, yet many perennial hold potential for future agricultural systems. In addition to multiyear harvests, perennials provide ecosystem services, including erosion control as a result their large persistent root However, the lifespan has been barrier rapid domestication breeding cycles require phenotyping over multiple growing seasons. Using phenomic selection, high-dimensional secondary traits measured on...
