|a In plants, glucose (Glc) plays pivotal roles in development and stress responses mainly by supplying fuel for growth and regulating expression of genes essential for crosstalk with hormonal, oxidative, and defense signaling. However, the complicated relationship between Glc and plant hormones is still not very clear. In this study, gsm3 (glucose-sensitive mutant 3), an Arabidopsis mutant with Glc-sensitive phenotype, was identified. Compared to wild type, the cotyledon expansion rate of gsm3 was significantly decreased under the condition of 4.5% Glc. Fluridone was able to rescue the Glc-induced defects of gsm3 in cotyledon expansion. AAO3 and ABI4 are key genes involved in abscisic acid (ABA) biosynthesis and signaling transduction, respectively. We found that inactivation of AAO3 or ABI4 in gsm3 background led to reduced sensitivity to Glc. These results indicated that increased ABA synthesis resulted in the sensitivity of gsm3 to Glc. Moreover, our results indicated that gsm3 mutant accumulated more ROS, which made it more sensitive to the application of exogenous H2O2. Overall, GSM3 plays an important role in Glc-ABA signaling cascade during seed germination and early seedling growth
