Control of seed dormancy and germination by DOG1-AHG1 PP2C phosphatase complex via binding to heme

Control of seed dormancy and germination by DOG1-AHG1 PP2C phosphatase complex via binding to heme

The hormone abscisic acid (ABA) prevents seeds from germination when conditions are not suitable. Here the authors show that DOG1, a positive regulator of germination, impairs ABA signaling via genetic and physical interactions with the AHG1 phosphatase and that DOG1 binding to heme is required for...

Sumario:The hormone abscisic acid (ABA) prevents seeds from germination when conditions are not suitable. Here the authors show that DOG1, a positive regulator of germination, impairs ABA signaling via genetic and physical interactions with the AHG1 phosphatase and that DOG1 binding to heme is required for this activity.
