Metabolite Signals Regulate Gene Expression and Source/Sink Relations in Cereal Seedlings

Our knowledge of the genetic structures and regulatory mechanisms active during cereal seedling development has increased dramatically in recent years. For this reason, a more integrated view of the molecular aspects of seedling development and physiology is needed. This review presents the Carbon Metabolite Signal Hypothesis, which attempts to explain how regulatory interactions between metabolite signals and hormonal signals participate in controlling gene expression, growth, and metabolism of the cereal seedling.
