Plant growth and development are controlled by the concerted action of many signaling pathways that integrate information from environmental signals with that from developmental and metabolic cues. Physiological studies have demonstrated that abscisic acid and sugars have both similar and antagonistic effects on diverse processes, including seed development, germination, and seedling growth. Recent genetic studies have identified several loci that are involved in both sugar and hormonal responses. It is rarely clear whether these apparent linkages reflect direct or indirect interactions between sugar and hormone signaling pathways, but the identification of gene products that are encoded at these loci is allowing these possibilities to be tested.
