Metabolomics Stems

Description

A dataset containing metabolomics variables measured on floral stems of five A. thaliana genotypes at two growth temperatures. See Ecotype and Temperature for more information.

Usage

data("Metabolomics_Stems")

Format

A data frame with 30 rows and 6 variables:

• Pectin_RGI: Rhamnogalacturonan I (µg/100mg)

• Pectin_HG: Homogalacturonan (µg/100mg)

• XG: Xyloglucan (µg/100mg)

• Pectin_linearity: Linearity of pectin (Ratio)

• Contribution_RG: Contribution of rhamnogalacturonan to pectin population (Ratio)

• RGI_branching: Branching of Rhamnogalacturonan I (Ratio)
