Study IDST000289
Study TitlePPDK RNAi effects in endosperm metabolite pools
Study SummaryMaize plants were transformed with endosperm-specific PPDK RNAi knockout constructs to alter starch/protein ratios. Metabolite pool comparisons will be examined from sibling kernels harvested from segregating ears.
