The domestic dog exhibits greater diversity in body size than any other terrestrial vertebrate. We used a strategy that exploits the breed structure of dogs to investigate genetic basis size. First, through genome-wide scan, we identified major quantitative trait locus (QTL) on chromosome 15 influencing variation within single breed. Second, examined 15-megabase interval surrounding QTL small and giant breeds found marked evidence for selective sweep spanning gene (IGF1), encoding...
Soybean [ Glycine max (L.) Merr.] yield, when regressed on water needed to replenish 0 100% seasonal evapotranspiration (ET), generates an estimate of season‐specific water‐use efficiency (WUE). The impact unpredictable deficits might be lessened if high‐yielding genotypes had a smaller beta. Our objective was determine the genetic basis beta and carbon isotope discrimination (CID), theorized indicator transpiration (TE). A ‘Minsoy’ × ‘Noir 1’ population 236 recombinant inbred lines (RILs),...
Abstract The first genetic transcript map of the soybean genome was created by mapping one SNP in each 1141 genes or more three recombinant inbred line populations, thus providing a picture distribution genic sequences across mapped portion genome. Single-nucleotide polymorphisms (SNPs) were discovered via resequencing sequence-tagged sites (STSs) developed from expressed sequence tag (EST) sequence. From an initial set 9459 polymerase chain reaction primer sets designed to diverse genes,...
Dog Coats Shed Genetic Secrets The coats of domestic dogs show great variation—long, short, straight, wavy, curly, wiry, or smooth. To investigate how this variation arises, Cadieu et al. (p. 150 , published online 27 August) performed genome-wide association studies on 80 different dog breeds. coat phenotype could be dissected into three simple traits length, curl, and growth pattern texture with each trait controlled by one major gene, FGF5 (fibroblast factor-5), KRT71 (keratin-71), RSPO2...
ABSTRACT Molecular markers provide a rapid approach to breeding for desired agronomic traits. To use them, it is necessary determine the linkage between quantitative trait loci (QTLs) and such markers. The objective of this research was in recombinant inbred (RI) soybean [ Glycine max (L.) Merrill] populations. do this, RI segregants were characterized molecular genetic traits measured several different environments. QTLs then identified by interval mapping. Agronomic compared large (about...
Many agronomic traits of interest to plant breeders are quantitative. Recombinant inbred (RI) lines particularly useful in genetic mapping studies quantitative traits. A recombinant population was derived from the Glycine max (L.) Merr. parents ‘Minsoy’ and ‘Noir 1’. This soybean used investigate basis several traits: days flower (Rl), maturity (R8), reproductive period (RS‐R1), height, lodging score, height divided by (the ability tall plants stand upright), seed protein content, oil size,...
A large recombinant inbred population of soybean has been characterized for 220 restriction fragment-length polymorphism (RFLP) markers. Values agronomic traits also have measured. Quantitative trait loci (QTL) height, yield, and maturity were located by their linkage to RFLP QTL controlling amounts variation analyzed the dependence on particular alleles at a second locus comparing cumulative distributions each genotype (four genotypes per pair loci). Interesting pairs statistically with...
Abstract Phenotypic stereotypes are traits, often polygenic, that have been stringently selected to conform specific criteria. In dogs, Canis familiaris, result from breed standards set for conformation, performance (behaviors), etc. As a consequence, phenotypic values measured on few individuals representative of the stereotype. We used DNA samples isolated 148 dog breeds associate SNP markers with stereotypes. Using size as trait test method, we identified six significant quantitative loci...
Evolution of mammalian skeletal structure can be rapid and the changes profound, as illustrated by morphological diversity domestic dog. Here we use principal component analysis variation in a population Portuguese Water Dogs to reveal systems traits defining structures. This classifies phenotypic into independent components that used dissect genetic networks regulating complex biological systems. We show unlinked quantitative trait loci associated with these individually promote both...
Soil waterlogging is a major environmental stress that suppresses soybean [ Glycine max (L.) Merr.] growth and yield. Our objective was to identify quantitative trait loci (QTL) associated with the tolerance of soil waterlogging. We subjected 208 lines two recombinant inbred (RI) populations, ‘Archer’ × ‘Minsoy’ ‘Noir I’, 2 wk when plants were at early flowering stage. The control not flooded. experiment conducted in three environments: Columbus, OH, 1997 1998 Wooster, 1998. identified...
ABSTRACT In order to breed efficiently, it is necessary identify individual quantitative trait loci (QTLs) as well interactions between these and determine which QTLs produce phenotypes that are environment specific. This can be done by linking molecular markers. The objective of this research was carry out such an analysis for yield, one the most complex agronomic traits. To do this, recombinant inbred lines soybean [ Glycine max (L.) Merrill] were characterized genetic markers analyzed...
Size sexual dimorphism occurs in almost all mammals. In Portuguese Water Dogs, much of the difference skeletal size between females and males is due to interaction a Quantitative Trait Locus (QTL) on X-chromosome QTL linked Insulin-like Growth Factor 1 (IGF-1) CFA 15 autosome. females, haplotype resulting small dominant. males, for large Females, homozygous at CHM marker X chromosome are, average, as males. However, that are heterozygous small, regardless their genotype. This suggests...
Traits that have been stringently selected to conform specific criteria in a closed population are phenotypic stereotypes. In dogs, Canis familiaris , such stereotypes produced by breeding for conformation, performance (behaviors), etc. We measured phenotypes on representative sample establish breed DNA samples from 147 dog breeds were used characterize single nucleotide polymorphism allele frequencies association mapping of identified significant size loci (quantitative trait [QTLs]),...
Abstract In dogs hip joint laxity that can lead to degenerative disease (DJD) is frequent and heritable, providing a genetic model for some aspects of the human disease. We have used Portuguese water (PWDs) identify Quantitative trait loci (QTLs) regulate in joint. A population 286 PWDs, each characterized by ca. 500 molecular markers, was analyzed subluxation as measured Norberg angle, quantitative radiographic measure laxity. significant directed asymmetry observed, such greater observed...
Summary Addison's disease, an immune‐mediated disorder caused by destruction of the adrenal glands, is a rare Western European populations. Studies indicate that polygenic in nature, involving specific alleles CTLA‐4, DRB1*04 and DQ, Cyp27B1, VDR MIC‐A ‐B loci. A similar immune form disease occurs several breeds domestic dog, with frequencies ranging from 1.5 to 9.0%. The high frequency dog likely reflects small number founders associated many breeds, subsequent inbreeding, frequent use...
