Gene Details:

• Gene ID: Zm00001eb303190
• Gene Symbol: ZmAGA1
• Gene Name: alkaline α-galactosidase 1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmAGA1 Hydrolyzes RFOs Late during the Lag Phase of Seed Germination, Shifting Sugar Metabolism toward Seed Germination Over Seed Aging Tolerance.
• We report here that maize alkaline α-galactosidase 1 (ZmAGA1) protein is translationally induced and is capable of hydrolyzing RFOs as well as a precursor, galactinol, during seed germination.
• ZmAGA1 overexpression also decreased the seed aging tolerance of mature, desiccated seeds as compared with wild type (WT) or those overexpressing GFP. Compared to that of WT control seeds, the atsip2 (mutant of Arabidopsis AtSIP2 (seed imbibition protein 2, encoding alkaline α-galactosidase)) seeds have similar RFOs and galactinol contents in mature, desiccated seeds but significantly increased the amount of these metabolites at 30 HAI.
• ZmAGA1 Is Translationally Induced and Capable of Hydrolyzing Galactinol and RFOs during Seed Imbibition.
