Abstract excerpt

KEY MESSAGE: AtGASA1 regulates plant growth and development, while conserved Cys-40 and Cys-44 residues in its GASA domain are crucial for controlling ROS accumulation under salt stress. AtGASA1 is a member of the gibberellin acid-stimulating protein (GASA) family, characterized by a GASA domain containing 12 conserved cysteine-rich peptides (CRP). Members of the GASA family are known to play an essential role in...
