Genetical Genomics: Successes and Prospects in Plants

摘要: Sequencing of expressed genes from several plant species has revealed that there is a relatively high level conservation in amino acid sequence among distantly related taxonomic groups, despite the tremendous phenotypic and developmental diversity kingdom. This appears to be primarily created by polymorphisms contribute quantitative gene expression variation, rather than protein structure modification or creation novel transcriptional units. A few studies have now demonstrated heritability dissection its genetic control plants. The approach – generally referred as genetical genomics relies on transcript trait loci (QTL) analysis transcriptome segregating populations. In this chapter we review principles genomics, results these plants, use dissect traits biological agricultural interest. Although still their infancy, pioneering shown valuable unravel networks implicated transcription regulation, for identification pathways variation. More important, they suggest integrative genomic methods, merge information variation at DNA, expression, metabolites will essential understanding complexity
