Study IDST001947
Study TitleMetabolite profiling of shoots of juvenile maize plants
Study TypeMetabolic diversity analysis
Study SummaryProfiles of primary metabolites in the shoots of juvenile maize inbred lines in the Goodman association panel were analyzed by GC-TOFMS to identify genetic components associated with metabolic control and plant performance. The samples also include those from landrace lines and maize wild relatives.

Processing Storage Conditions:Room temperature
Extract Storage:Room temperature
Sample Resuspension:pyridine
Sample Derivatization:methoxyamination and trimethylsilylation
Sample Spiking:8.2 ug/ml ribitol
