Genome-wide QTL analysis in combination with a genetical-genomics approach reveals new candidate genes for the control of tuber carotenoid content in potato
Ontology highlight
ABSTRACT: The aim of this study was to conduct a genome-wide analysis for constituent tuber carotenoid QTL. Using a genetical genomics approach samples from clones with similar carotenoid traits were bulked and patterns of gene expression were measured for each bulk by microarray analysis. Variation of gene expression within these bulks may be due to either polymorphisms located near to or within the gene (cis-eQTL) or indirectly from a distant location on the genome (trans-eQTL). Differentially expressed clones from bulks with contrasting carotenoid traits were genetically mapped in order to re-enforce the QTL analysis, and provide a rapid means of developing gene markers closely associated with the target traits.
