Starch metabolism and antiflorigenic signals modulate the juvenile-to-adult phase transition in Arabidopsis.

Abstract excerpt

The physiology and genetics underlying juvenility is poorly understood. Here, we exploit Arabidopsis as a system to understand the mechanisms that regulate floral incompetence during juvenility. Using an experimental assay that allows the length of juvenility to be estimated and mutants impaired in different pathways, we show that multiple inputs influence juvenility. Juvenile phase lengths of wild type (WT)...
