QTL Mapping in New Arabidopsis thaliana Advanced Intercross-Recombinant Inbred Lines
BACKGROUND Even when phenotypic differences are large between natural or domesticated strains, the underlying genetic basis is often complex, and causal genomic regions need to be identified by quantitative trait locus (QTL) mapping. Unfortunately, QTL positions typically have large confidence intervals, which can, for example, lead to one QTL being masked by another, when two closely linked lo...
متن کاملNew Arabidopsis advanced intercross recombinant inbred lines reveal female control of nonrandom mating.
Female control of nonrandom mating has never been genetically established, despite being linked to inbreeding depression and sexual selection. In order to map the loci that control female-mediated nonrandom mating, we constructed a new advanced intercross recombinant inbred line (RIL) population derived from a cross between Arabidopsis (Arabidopsis thaliana) accessions Vancouver (Van-0) and Col...
متن کاملBreeding designs for recombinant inbred advanced intercross lines.
Recombinant inbred lines derived from an advanced intercross, in which multiple generations of mating have increased the density of recombination breakpoints, are powerful tools for mapping the loci underlying complex traits. We investigated the effects of intercross breeding designs on the utility of such lines for mapping. The simplest design, random pair mating with each pair contributing ex...
متن کاملMapping Isoflavone QTL with Main, Epistatic and QTL × Environment Effects in Recombinant Inbred Lines of Soybean
Soybean (Glycine max (L.) Merr.) isoflavone is important for human health and plant defense system. To identify novel quantitative trait loci (QTL) and epistatic QTL underlying isoflavone content in soybean, F5:6, F5:7 and F5:8 populations of 130 recombinant inbred (RI) lines, derived from the cross of soybean cultivar 'Zhong Dou 27' (high isoflavone) and 'Jiu Nong 20' (low isoflavone), were an...
متن کاملQTL Mapping: Overview and Using Inbred Lines
While the machinery of quantitative genetics can blissfully function in complete ignorance of any of the underlying genetic details, we are certainly interested (at least one some level) on the genetic basis of trait variation. At the most practical level, if a gene of major effect is segregating in our population of interest, we would certainly like to not only to be aware of this, but also to...
