Input (English): The CY707A gene codes for this molecule's namesake 8-hydroxylase and is the first step of its degradation. This compound can be activated by oxidation to phaseic and dihydrophaseic acid, and one precursor to this molecule is synthesized by NCE decarboxylase, which cleaves a C40 zeaxanthin precursor to xanthoxin. It helps prevent dessication of roots during soil compaction, and during water stress signals the guard cells to collapse and close stomata. Its opposed in its most important function by gibberelin, and in that role suppresses the synthesis of alpha-amylase and upregulates the synthesis of storage proteins. For 10 points, name this plant hormone responsible for seed dormancy.
Output (English): Science
