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,...
The classic domestication scenario for grains and fruits has been portrayed as the lucky fixation of major-effect "domestication genes." Characterization these genes plus recent improvements in generating novel alleles (e.g., by gene editing) have created great interest de novo new crops from wild species. While editing technologies may accelerate some genetic aspects domestication, we caution that should be understood an iterative process rather than a singular event. Changes human social...
Determination of microsatellite lengths or other DNA fragment types is an important initial component many genetic studies such as mutation detection, linkage and quantitative trait loci (QTL) mapping, diversity, pedigree analysis, detection heterozygosity. A handful commercial freely available software programs exist for analysis; however, most them are platform dependent lack high-throughput applicability. We present the R package Fragman to serve a independent resource automatic scoring...
Increasing cropping system diversity has great potential to address environmental problems associated with modern agriculture, such as erosion, soil carbon loss, nutrient runoff, water pollution, and loss of biodiversity. As other agricultural sciences, plant breeding primarily been conducted in the context dominant monoculture systems, little focus on multicrop systems. Multicrop systems have increased temporal and/or spatial include a diverse set crops practices. In order support...
The development of high-throughput genotyping has made genome-wide association (GWAS) and genomic selection (GS) applications possible for both model non-model species. exploitation genome-assisted approaches could greatly benefit breeding efforts in American cranberry (Vaccinium macrocarpon) other minor crops. Using biparental populations with different degrees relatedness, we evaluated multiple GS methods total yield (TY) mean fruit weight (MFW). Specifically, compared predictive ability...
Abstract Onobrychis viciifolia (hereafter sainfoin) is an autotetraploid (2 n = 4 x 28), allogamous insect‐pollinated perennial legume originating from the Caucasus that has historically been cultivated as a forage. As legume, sainfoin potential to improve sustainability of agriculture and food systems in multiple ways. Sainfoin can provide continuous living cover biological nitrogen fixation enhance soil fertility health. It also ecosystem services resource for pollinators wildlife addition...
The American cranberry, Vaccinium macrocarpon Ait., is an economically important North fruit crop that consumed because of its unique flavor and potential health benefits. However, a lack abundant, genome-wide molecular markers has limited the adoption modern assisted selection approaches in cranberry breeding programs. To increase number available species, this study identified, tested, validated microsatellite from existing nuclear transcriptome sequencing data. In total, new primers were...
The application of genotyping by sequencing (GBS) approaches, combined with data imputation methodologies, is narrowing the genetic knowledge gap between major and understudied, minor crops. GBS an excellent tool to characterize genomic structure recently domesticated (~200 years) understudied species, such as cranberry (Vaccinium macrocarpon Ait.), generating large numbers markers for studies mapping. We identified 10842 potentially mappable single nucleotide polymorphisms (SNPs) in a...
Image-based phenotyping methodologies are powerful tools to determine quality parameters for fruit breeders and processors. The size shape of American cranberry (Vaccinium macrocarpon L.) particularly important characteristics that the harvests' processing value potential end-use products (e.g., juice vs. sweetened dried cranberries). However, attributes can be difficult time consuming processors measure, especially when relying on manual measurements visual ratings. Therefore, in this...
Integrating perennial groundcovers (PGC) — sometimes referred to as living mulches or cover crops into annual cash-crop systems could address root causes of bare-soil practices that lead negative impacts on soil and water quality. Perennial bring otherwise absent functional traits namely perenniality preserve regenerate water, carbon, nutrient cycles. However, if not optimized, they can also cause competitive interactions yield loss. When designing PGC systems, the goal is maximize...
Conversion from annual to perennial grains such as intermediate wheatgrass Kernza ® could sequester soil organic carbon (SOC). To date, no studies have quantified SOC under on working farms. We sampled three sites with paired fields and converted 5–17 years ago 100 cm compared their stocks distributed between mineral-associated matter (MAOM) particulate (POM). POM-C was higher cultivation but total MAOM-C were similar. Our findings suggest that increases at depth POM. Further study is needed...
Abstract Perennial groundcover (PGC) research is an expanding field of study focused on utilizing the soil‐protecting characteristics perennial plants as permanent intercrops in row‐crop agriculture systems. However, there are some risks that PGC could serve a “green bridge” between cash crops. Alfalfa mosaic virus (AMV) one such disease infect legume PGCs, like kura clover ( Trifolium ambiguum M. Bieb), and potentially be transmitted to cash‐crop companions (e.g., soybean). The objectives...
Sugarbeet is a major source of refined sucrose and increasingly grown for biofuel production. Demand higher productivity this crop requires greater knowledge sugarbeet physiology, pathology, genetics, which can be advanced by the development new genomic resources. Towards end, transcriptome expressed genes from leaf root tissues at varying stages production, after elicitation with jasmonic acid (JA) or salicylic (SA), was constructed used to generate simple sequence repeat (SSR) markers. The...
Annual cereal and legume grain production is dependent on inorganic nitrogen (N) other fertilizers inputs to resupply nutrients lost as harvested grain, via soil erosion/runoff, by natural or anthropogenic causes. Temperate-adapted perennial legumes, though currently non-existent, might be uniquely situated crop plants able provide relief from reliance synthetic while supplying stable yields of highly nutritious seeds in low-input agricultural ecosystems. As such, breeding domestication...
The American cranberry (Vaccinium macrocarpon Ait.) is a recently domesticated, economically important, fruit crop with limited molecular resources. New genetic resources could accelerate gain in through characterization of its genomic structure and by enabling molecular-assisted breeding strategies. To increase the availability resources, genotyping-by-sequencing (GBS) was used to discover genotype thousands single nucleotide polymorphisms (SNPs) within three interrelated full-sib...
Societal Impact Statement Agroecosystems are constantly evolving to meet the needs of a growing population in sustainable manner. Concerns about ecological impacts agriculture, including soil loss, have focused attention on crops that provide both agricultural products and services. Perennial, herbaceous live for multiple years can be harvested mechanically produce large root systems may reduce loss; however, these species largely absent from agriculture. The diversity wild, perennial,...
Traditional methods for trait phenotyping have been a bottleneck research in many crop species due to their intensive labor, high cost, complex implementation, lack of reproducibility and propensity subjective bias. Recently, multiple high-throughput platforms developed, but most them are expensive, species-dependent, use, available only major crops. To overcome such limitations, we present the open-source software GiNA, which is simple free tool measuring horticultural traits as shape-...
American cranberry (Vaccinium macrocarpon) is a perennial, woody plant species, native to North bogs and wetlands. Cranberries represent one of the few agriculturally important plants in which wild gene pools are still readily available within undeveloped wetlands northern US Canada. Earlier studies have reported low genetic variation V. macrocarpon at species population level. However, this study, we characterised 229 individuals oxycoccos (small cranberry) from Wisconsin 22 accessions...
