Fixed arrays of single nucleotide polymorphism (SNP) markers have advantages over reduced representation sequencing in their ease data analysis, consistently higher call rates, and rapid turnaround times. A 6 K SNP array represents a cost-benefit "sweet spot" for routine genetics breeding applications rice. Selection informative SNPs across species subpopulations during chip design is essential to obtain useful rates target germplasm groups. This paper summarizes results from large-scale...
While a multitude of genotyping platforms have been developed for rice, the majority them not optimized breeding where cost, turnaround time, throughput and ease use, relative to density informativeness are critical parameters their utility. With that in mind we report development 1K-Rice Custom Amplicon, or 1k-RiCA, robust custom sequencing-based amplicon panel ~ 1000-SNPs uniformly distributed across rice genome, designed be highly informative within indica pools, tailored genomic...
A range of resistance loci against different races Xanthomonas oryzae pv. (Xoo), the pathogen causing bacterial blight (BB) disease rice, have been discovered and characterized. Several deployed in modern varieties, however, due to rapid evolution Xoo, a number already become ineffective. The continuous "arms race" between Xoo rice makes it imperative discover new enable durable deployment multiple genes breeding lines. Rice diversity panels can be exploited as reservoirs useful genetic...
Abstract Background Improvement of α-tocopherol content is an important breeding aim to increase the nutritional value crops. Several efforts have been conducted improve in soybean [ Glycine max (L.)

Colored rice is rich in nutrition and also a good source of valuable genes/quantitative trait loci (QTL) for nutrition, grain quality, pest disease resistance traits use breeding. Genome-wide association analysis using high-density single nucleotide polymorphism (SNP) useful precisely detecting QTLs genes. We carried out genome-wide 152 colored accessions, 22,112 SNPs to map nutritional, agronomic, bacterial leaf blight (BLB) traits. Wide variations normal frequency distributions were...
Tocopherols, known as members of vitamin E, are the major lipophilic antioxidants in soybean. Since soybean seeds contain a low concentration α-tocopherol (α-Toc), tocopherol isoform with highest E activity, some breeding efforts have been implemented to increase content seeds. In present study, we used F2 seed and plant (F3 seeds) populations derived from cross between variety high content, Keszthelyi A.S. (α-Toc 20–30%) Japanese cultivar, Ichihime < 10%) for genetic analysis concentration....
The development, dissemination, and adoption of improved rice varieties are imperative for global food nutritional security. Knowledge the crop's distribution across agro-ecologies is important impact assessment studies, varietal replacement strategies, development implementation agricultural policies. Bangladesh world's 4th largest producer. Though traditional (TVs) abundant valued throughout Bangladesh, population growth vulnerability to climate change, necessitate efficient deployment...
Abstract To breed improved biomass cultivars of Miscanthus ×giganteus, it will be necessary to select the highest‐yielding and best‐adapted genotypes its parental species, sinensis sacchariflorus . We phenotyped a diverse clonally propagated panel 569 M. nine natural diploid M × giganteus at one subtropical (Zhuji, China) five temperate locations (Sapporo, Japan; Leamington, Ontario, Canada; Fort Collins, CO; Urbana, IL; Chuncheon, Korea) for dry yield 14 yield‐component traits, in trials...
Abstract Background Soybean is one of the most important crop sources tocopherols (Toc). However, content α-Toc, an isoform with highest vitamin E activity in humans, low cultivars. With aim broadening genetic variability, we performed quantitative trait locus (QTL) analysis for a high seed α-Toc detected wild soybean and characterized sequence polymorphisms expression profiles γ-tocopherol methyltransferase ( γ-TMT ) genes as potential candidates. Results A recombinant inbred line...
Ionomic profiles are primarily influenced by genetic and environmental factors. Identifying ionomic responses to varietal effects is necessary understand the variations among species or subspecies potentially on profiles. We cultivated 120 rice (Oryza sativa) varieties seedling stage in identical hydroponic conditions determined concentrations of 26 elements (including 3 anions) shoots roots rice. Although were limited genus Oryza pre-framework its elemental chemical properties, we found...
Abstract Miscanthus is a high‐yielding bioenergy crop that broadly adapted to temperate and tropical environments. Commercial cultivation of predominantly limited single sterile triploid clone × giganteus , hybrid between sacchariflorus M. sinensis. To expand the genetic base substantial diversity within its progenitor species should be used for cultivar improvement diversification. Here, we phenotyped panel 605 from six previously described groups 27 genotypes dry biomass yield 16...
The timing of both flowering and maturation determine crop adaptability productivity. Soybean (Glycine max) is cultivated across a wide range latitudes. molecular-genetic mechanisms for in soybean have been determined photoperiodic responses to long days (LDs), but remain only partially the delay under short-day conditions, an adaptive trait cultivars grown lower Here, we characterized late-flowering (LF) habit introduced from Thai cultivar K3 into photoperiod-insensitive genetic background...
Ambient growing temperature and photoperiod are major environmental stimuli that summer annual crops use to adjust their reproductive phenology so as maximize yield. Variation in flowering time among soybean (Glycine max) cultivars results mainly from allelic diversity at loci control sensitivity FLOWERING LOCUS T (FT) orthologs. However, variation the thermal regulation of its underlying mechanisms poorly understood. In this study, we identified a novel mutant confers altered response cool...
Abstract Species within the genus Miscanthus show potential as sustainable bioenergy crops given their low nutrient requirements and high biomass yields. One such species, sinensis , has a wide natural distribution phenotypic variation, including its seed germination characteristics. Such characteristics need to be considered, particularly in ensuring plant establishment regions with harsh winters. Germination rates were measured for 33 M. accessions from different latitudinal Japan....
Abstract To improve the efficiency of breeding Miscanthus for biomass yield, there is a need to develop genomics‐assisted selection this long‐lived perennial crop by relating genotype phenotype and value across broad range environments. We present first genome‐wide association (GWA) genomic prediction study that utilizes multilocation phenotypic data. A panel 568 sinensis accessions was genotyped with 46,177 single nucleotide polymorphisms (SNPs) evaluated at one subtropical five temperate...
Alpha-tocopherol is one of four tocopherol isoforms and has the highest vitamin E activity in humans. Most cultivated soybean seeds contain γ-tocopherol as predominant form, ratio α-tocopherol content to total (α-tocopherol ratio) <10%. Three accessions from Eastern Europe have ratios >20%. This higher likely due mutations promoter region methytransferase-3 (γ-TMT3) gene. We surveyed a wild germplasm collection detected 16 with stable seed >20% under different growth conditions. The were...
Discovery and analysis of genetic variants underlying agriculturally important traits are key to molecular breeding crops. Reduced representation approaches have provided cost-efficient genotyping using next-generation sequencing. However, accurate genotype calling from sequencing data is challenging, particularly in polyploid species due their genome complexity. Recently developed Bayesian statistical methods implemented available software packages, polyRAD, EBG, updog, incorporate error...
