The GIBBERELLIN INSENSITIVE DWARF1 (GID1) gene encodes a receptor integral to Gibberellic acid (GA) signaling, which is pivotal for plant growth, development, and stress responses. Until now, GID1 genes have not been documented in mango. In this research, the mango (Mangifera indica) genome yielded four GID1 homologous genes, and this study focuses on the research of MiGID1A and MiGID1B genes. Expression analysis indicated that MiGID1A is mainly expressed in leaves, while MiGID1B is predominantly found in flowers and buds. Both genes exhibited a significant upsurge in expression under salt and drought stress conditions. Moreover, the overexpression of these genes significantly advanced early flowering under long-day conditions. MiGID1A and MiGID1B transgenic plants showed significantly higher root length and survival rate than WT plants under drought and salt stress treatment. In addition, under drought and salt stress treatment, the contents of malonaldehyde (MAD) and hydrogen peroxide (H
