Rapid creation of Arabidopsis doubled haploid lines for quantitative trait locus mapping.
Quantitative trait loci (QTL) mapping is a powerful tool for investigating the genetic basis of natural variation. QTL can be mapped using a number of different population designs, but recombinant inbred lines (RILs) are among the most effective. Unfortunately, homozygous RIL populations are time consuming to construct, typically requiring at least six generations of selfing starting from a het...
متن کاملQuantitative trait Loci for panicle layer uniformity identified in doubled haploid lines of rice in two environments.
Uniformity of stem height in rice directly affects crop yield potential and appearance, and has become a vital index for rice improvement. In the present study, a doubled haploid (DH) population, derived from a cross between japonica rice Chunjiang 06 and indica rice TN1 was used to analyze the quantitative trait locus (QTL) for three related traits of panicle-layer-uniformity; that is, the tal...
متن کاملAdvances in Quantitative Trait Locus Mapping
The mapping of loci underlying variation in quantitative traits is proving to be a powerful tool in genetic studies of animals and other organisms. Quantitative trait locus (QTL) mapping in crosses between genetically diverse lines has shown the presence of many QTL, as similarly have studies within livestock populations. Although much remains to be done with this type of analysis, higher resol...
متن کاملMapping quantitative trait loci by genotyping haploid tissues.
Mapping strategies based on a half- or full-sib family design have been developed to map quantitative trait loci (QTL) for outcrossing species. However, these strategies are dependent on controlled crosses where marker-allelic frequency and linkage disequilibrium between the marker and QTL may limit their application. In this article, a maximum-likelihood method is developed to map QTL segregat...
متن کاملCombined Expression Trait Correlations and Expression Quantitative Trait Locus Mapping
Coordinated regulation of gene expression levels across a series of experimental conditions provides valuable information about the functions of correlated transcripts. The consideration of gene expression correlation over a time or tissue dimension has proved valuable in predicting gene function. Here, we consider correlations over a genetic dimension. In addition to identifying coregulated ge...
