| Project Title: | Metabolomic analysis of tomato seed germination |
| Project Summary: | Genomic approaches have accelerated the study of the quantitative genetics that underlie phenotypic variation. We have utilized gas chromatography-time-of-flight/mass spectrometry (GC-TOF-MS) metabolite profiling to characterize tomato seeds during dry and imbibed stages using a recombinant inbred line (RIL) population of Solanum lycopersicum x Solanum pimpinellifolium. In this article we describe, for the first time in tomato, the use of a generalized genetical genomics (GGG) model to study metabolite changes in tomato seeds incorporating genetics as well as environmental effects in a single QTL analysis. The GGG design was used to map genetic quantitative trait loci (G QTLs) and environmental changes by genetic-by-environment interactions (G x E QTLs). A significant canonical correlation was found between metabolites and seed quality traits, revealing a close link between seed quality phenotypes and a specific combination of metabolites. Densely connected metabolites were extracted using graph clustering from correlation networks, and the clusters were evaluated by biochemical-pathway enrichment analysis. The evidence from this study suggests that the number of significant correlations varied among individual metabolites and that the obtained clusters were significantly enriched for metabolites involved in specific biochemical pathways. Thus, the methods described here have the potential to reveal regulatory networks that contribute to our understanding of the complex nature of seed quality. |
