Elucidating cis- and trans-regulatory variation using genetical genomics.
Genetic variation, through its effects on gene regulatory networks, has an important role in determining biologic phenotypes and disease susceptibility. Recent studies using segregating populations have characterized variation in gene expression resulting from genetic differences and have used well-established assays to identify many cis-acting polymorphisms. Although trans effects have been sh...
متن کاملGenetic dissection of leaf development in Brassica rapa using a genetical genomics approach.
The paleohexaploid crop Brassica rapa harbors an enormous reservoir of morphological variation, encompassing leafy vegetables, vegetable and fodder turnips (Brassica rapa, ssp. campestris), and oil crops, with different crops having very different leaf morphologies. In the triplicated B. rapa genome, many genes have multiple paralogs that may be regulated differentially and contribute to phenot...
متن کاملGenetical metabolomics of flavonoid biosynthesis in Populus: a case study.
Genetical metabolomics [metabolite profiling combined with quantitative trait locus (QTL) analysis] has been proposed as a new tool to identify loci that control metabolite abundances. This concept was evaluated in a case study with the model tree Populus. Using HPLC, the peak abundances were analyzed of 15 closely related flavonoids present in apical tissues of two full-sib poplar families, Po...

متن کاملAdvances in Genetical Genomics of Plants
Natural variation provides a valuable resource to study the genetic regulation of quantitative traits. In quantitative trait locus (QTL) analyses this variation, captured in segregating mapping populations, is used to identify the genomic regions affecting these traits. The identification of the causal genes underlying QTLs is a major challenge for which the detection of gene expression differe...
