A better understanding of the extent convergent selection among crops could greatly improve breeding programs. We found that quantitative trait locus KRN2 in maize and its rice ortholog, OsKRN2, experienced selection. These orthologs encode WD40 proteins interact with a gene unknown function, DUF1644, to negatively regulate grain number both crops. Knockout or OsKRN2 increased yield by ~10% ~8%, respectively, no apparent trade-offs other agronomic traits. Furthermore, genome-wide scans...
Maize was domesticated from lowland teosinte (Zea mays ssp. parviglumis), but the contribution of highland mexicana, hereafter mexicana) to modern maize is not clear. Here, two genomes for Mo17 (a inbred) and mexicana are assembled using a meta-assembly strategy after sequencing 10 lines derived maize-teosinte cross. Comparative analyses reveal high level diversity between Mo17, B73, including three Mb-size structural rearrangements. The spontaneous mutation rate estimated be 2.17 × 10-8...
Plant height has long been an important agronomic trait in maize breeding. Many plant QTLs have reported, but few of these cloned. In this study, a major QTL, qph1, was mapped to 1.6kb interval Brachytic2 (Br2) coding sequence on chromosome 1. A naturally occurring rare SNP which resulted amino acid substitution, validated as the causative mutation. QPH1 protein is located plasma membrane and polar auxin transport impaired short near-isogenic line RIL88(qph1). Allelism testing showed that...
High-quality genotypic data is a requirement for many genetic analyses. For any crop, errors in genotype calls, phasing of markers, linkage maps, pedigree records, and unnoticed variation ploidy levels can lead to spurious marker-locus-trait associations incorrect origin assignment alleles individuals. High-throughput genotyping requires automated scoring, as manual inspection thousands scored loci too time-consuming. However, SNP scoring result that should be corrected ensure recorded are...
The apple (Malus×domestica) cultivar Honeycrisp has become important economically and as a breeding parent. An earlier study with SSR markers indicated the original recorded pedigree of 'Honeycrisp' was incorrect 'Keepsake' identified one putative parent, other being unknown. objective this to verify parent identify genetically describe unknown its grandparents. A multi-family based dense high-quality integrated SNP map created using 8 K Illumina Infinium array. This used alongside large...
Summary Globally, weedy plants are a major constraint to sustainable crop production. Much of the success weeds rests with their ability rapidly adapt in face human‐mediated management agroecosystems. Alopecurus myosuroides (blackgrass) is widespread and impactful weed affecting agriculture Europe. Here we report chromosome‐scale genome assembly blackgrass use this reference explore genomic/genetic basis non‐target site herbicide resistance (NTSR). Based on our analysis F2 seed families...
Sweet cherry is consumed widely across the world and provides substantial economic benefits in regions where it grown. While breeding has been conducted Pacific Northwest for over half a century, little known about genetic architecture of important traits. We used genome-enabled mixed model to predict performance 505 individuals 32 phenological, disease response fruit quality traits evaluated RosBREED sweet crop data set. Genome-wide predictions were estimated using repeated measures...
Fruit quality traits have a significant effect on consumer acceptance and subsequently peach (Prunus persica (L.) Batsch) consumption. Determining the genetic bases of key fruit is essential for industry to improve increase Pedigree-based analysis across multiple pedigrees can identify genomic basis complex direct implementation in marker-assisted selection. This strategy provides breeders with better-informed decisions improves selection efficiency and, subsequently, saves resources time.
Abstract Genomic regions associated with ripening time (RPT) and soluble solids concentration (SSC) were mapped using a pedigreed population including multiple F 1 2 families from the Clemson University peach breeding program (CUPBP). RPT SSC QTLs consistently identified in two seasons (2011 2012) average datasets (average of seasons). A target region spanning 10,981,971–11,298,736 bp on chromosome 4 reference genome used for haplotype analysis revealed four haplotypes significant...
Abstract Fruit firmness is an important market driven trait in sweet cherry ( Prunus avium L.) where the desirable increase fruit associated with landrace and bred cultivars. The aim of this work was to investigate genetic basis using plant materials that include wild (syn. mazzard), germplasm. A major QTL for firmness, named qP-FF4.1 , had not previously been reported, identified three populations. Thirteen haplotypes (alleles) either soft or firm were germplasm, “soft” alleles dominant...
Bloom time in sweet cherry (Prunus avium L.) is a highly heritable trait that varies between genotypes and depends on the environmental conditions. Bud-break occurs after chill heat requirements of each genotype are fulfilled, dormancy released. critical for fruit production as matching cultivar adaptation to growing area essential adequate set. Additionally, low chilling cultivars interest extend warmer regions, crop increasing winter spring temperatures. The aim this work investigate...
Peach is one of the most important fruit crops in world, with global annual production about 24.6 million tons. The United States fourth-largest producer after China, Spain, and Italy. consumption has decreased over last decade, likely due to inconsistent quality on market. Thus, marker-assisted selection for traits highly desired fresh market peach breeding programs major goals RosBREED project. ability use DNA information select desirable would enable breeders efficiently plan crosses...
The timing of fruit maturity is an important trait in sweet cherry production and breeding. Phenotypic variation for phenology appears to be under strong genetic control, but that control might complicated by phenotypic instability across environments. Although such genotype-by-environment interaction (G × E) a common phenomenon crop plants, knowledge about it lacking other traits. In this study, 1673 genome-wide SNP markers were used estimate genomic relationships among 597 weakly...
Abstract Cherry breeding and genetic studies can benefit from genome-wide marker assays. Currently, a 6K SNP array enables genome scans in cherry; however, only third of these SNPs are informative, with low coverage many genomic regions. Adding previously detected to this could provide cost-efficient upgrade increased across the 670 cM/352.9 Mb cherry whole sequence. For sweet cherry, new were chosen following focal point strategy, grouping six eight within 10-kb windows an average 0.6 cM...
Abstract Background Environmental adaptation and expanding harvest seasons are primary goals of most peach [ Prunus persica (L.) Batsch] breeding programs. Breeding perennial crops is a challenging task due to their long cycles large tree size. Pedigree-based analysis using pedigreed families followed by haplotype construction creates platform for QTL marker identification, validation, the use marker-assisted selection in Results Phenotypic data seven F 1 low medium chill full-sib were...

Much of the cost associated with marker discovery for assisted breeding (MAB) can be eliminated if a diverse, segregating population is generated, genotyped, and made available to global community. Herein, we present an example hybrid, wild-derived family octoploid strawberry that used by other programs economically find tag useful genes MAB. A pseudo test cross between two wild species Fragaria virginiana F. chiloensis (FVC 11) was generated evaluated set phenotypic traits. total 106...
In the last decade, with advent of next-generation sequencing technologies, numerous molecular markers have become available for genetic studies in sweet and sour cherries. Thanks to these tools, saturated linkage maps been built several countries allowing detection quantitative trait loci (QTLs). Hence, marker-assisted selection (MAS) has now a reality crops. Given that cherry is species long period juvenility large areas are needed evaluate thousands new hybrids, MAS will allow breeders...
Black spot disease (Diplocarpon rosae) is the most important leaf of garden roses in warm humid areas. Although partial resistance to black has been shown be moderately heritable, responsible quantitative trait loci (QTL) remain unidentified. Because interspecific nature and high heterozygosity commercial roses, as well relatively small research input compared row crops, genomic resources available for rose are limited. To effectively identify markers associated with QTL controlling...
