Genome-wide expression quantitative trait loci (eQTL) analysis in maize

Abstract: BackgroundExpression QTL analyses have shed light on transcriptional regulation in numerous species of plants, animals, and yeasts. These microarray-based analyses identify regulators of gene expression as either cis-acting factors that regulate proximal genes, or trans-acting factors that function through a variety of mechanisms to affect transcript abundance of unlinked genes.ResultsA hydroponics-based genetical genomics study in roots of a Zea mays IBM2 Syn10 double haploid population identified tens of tho… Show more

“…A slight majority (54.0%) of eQTLs were local at an FDR of 0.1. However, consistent with other studies (Holloway et al, 2011), the ratio of local to distant eQTLs was sensitive to the FDR threshold, with local eQTLs becoming proportionally more abundant at more stringent thresholds (Table 1).…”

“…Here, mRNA transcript abundance for each gene in the genome is treated as a trait for genetic mapping. Over the last decade, eQTL mapping has been used to understand the genetic architecture of variation in gene expression in model systems, crops, and humans (Brem et al, 2002;DeCook et al, 2006;West et al, 2007;Smith and Kruglyak, 2008;Kliebenstein, 2009;Holloway et al, 2011;Grundberg et al, 2011;Maranville et al, 2011;Zhang et al, 2011;Barreiro et al, 2012;Cubillos et al, 2012aCubillos et al, , 2012bSnoek et al, 2012). More recently, studies have begun to explore how eQTL effects on transcript abundance can interact with the environment (Li et al, 2006;Smith and Kruglyak, 2008;Grundberg et al, 2011;Maranville et al, 2011;Barreiro et al, 2012).…”

“…Fourth, the maize materials for genotyping by the three platforms are not from the same plants, the residual heterozygosis of inbred lines may also be a factor influencing the concordant rate. Regulation of expression variation may be broadly defined by traditional linkage studies 22,39 . In experimental populations from two parental lines, eQTL mapping resolution is limited by population size.…”

“…In plants a number of studies have been conducted on a range of species including Arabidopsis thaliana, barley (Hordeum vulgare), maize (Zea mays), poplar (Populus spp. ), and wheat (Triticum aestivum) (Decook et al 2006;Jordan et al 2007;Keurentjes et al 2007;West et al 2007;Potokina et al 2008;Drost et al 2010;Druka et al 2010;Holloway et al 2011;Zhang et al 2011). Using a genetical genomics approach, gene expression by environment interaction has been studied in Caenorhabditis elegans and yeast, but to date no studies in plants have taken advantage of gene expression measurements in more than one environment to help in understanding G·E (Li et al 2006;Smith and Kruglyak 2008).…”
