Our previous study has shown that MAIGO2 (MAG2) is a subunit of the Golgi/endoplasmic reticulum (ER) multi-subunit tethering complex, and is required for tolerance to general osmotic stresses and abscisic acid and response to ER stress during seed germination and early growth. MAG2 is crucial for multi-environmental stress responses. To verify this hypothesis, the response of mag2 mutants to gibberellic acid (GA), sugar, and heat shock was described in this study. The mag2 mutants showed defects during seed germination and early seedling development under treatments with the GA biosynthesis inhibitor paclobutrazol, sucrose, and glucose. MAG2 is also essential for basal thermotolerance. However, the MAG2 homolog (MAG2L) is not necessary for these responses. MAG2 is an important regulator in the response to multi-environmental stimuli, supposedly through its roles in Golgi/ER retrograde trafficking and ER stress response.
