Constitutive metabolomic profile of a transgressive segregant of rice with superior salinity tolerance potentials due to unique morphological features and well-modulated growth

Understanding the nature of non-parental phenotypes created by transgressive segregation is important in creating novel genetic recombinants that can withstand different environmental conditions for crop production. FL510, a transgressive salinity-tolerant rice genotype from a cross between IR29 (xian/indica; salt-sensitive) and Pokkali (indica/aus; salt-tolerant), has tolerance mechanisms active under control conditions and improves survival upon the onset of salinity. This study compares normal-state metabolomes and lipidomes of FL510 with those of its parents. Principal component analysis (PCA) of the identified analytes showed clear and expected similarity between FL510 and Pokkali, while partial least squares discriminant analysis (PLS-DA) emphasized overlaps between the metabolic profiles of IR29 and FL510. The analysis identified metabolites with inherited patterns of abundance from either parent in FL510 and those with unique, non-parental abundances, and these were supported by..., , # Data from: Constitutive metabolomic profile of a transgressive segregant of rice with superior salinity tolerance potentials due to unique morphological features and well-modulated growth

## Description of the data and file structure

Samples: Leaf blades from one-month-old plants

Genotypes: FL510 (transgressive salt tolerant recombinant inbred line); IR29 (salt sensitive parent); Pokkali (salt tolerant parent)

Dataset: metabolites identified through shotgun approach. Four total datasets are included, as metabolites were detected from the metabolome (aqueous phase extract) and lipidome (organic phase extract) at both positive and negative ion modes. Each file contains a tab for raw values and a tab for values normalized with a set internal standard listed on row 1. QC sample peaks are also included. These samples were combined extracts from the three genotypes listed above and were used to ensure run quality for the e..., ,
