Metabolite Quantitative Trait Loci Mapping for Fragrance and Fatty Acid Composition in Rice (Oryza Sativa L.).

ABSTRACT:

Background

Fragrance is a premium trait of grain quality in the traditional, Jasmine-style rice (Oryza sativa L.) variety Phka Rumduol (PRD). Rice fragrance is a combination of various volatile compounds with characteristic odours and flavours that can be traced back to fatty acids. Given the complexity of fragrance phenotype, the use of a robust phenotyping platform in identifying metabolite quantitative trait loci (mQTL) is essential to providing the most suitable set of genetic markers associated with desirable fragrance metabolites and their fatty acid origins in PRD-derived rice breeding lines.

Results

Using combined untargeted metabolomics via GC×GC-TOF-MS, targeted fatty acid analysis with GC-MS, mQTL for individual volatile compounds and fatty acids were identified i
