Comparative transcriptome analysis reveals the potential mechanism of GA₃-induced dormancy release in Suaeda glauca black seeds.

ABSTRACT: Suaeda glauca Bunge produces dimorphic seeds on the same plant, with brown seeds displaying non-dormant characteristics and black seeds exhibiting intermediate physiological dormancy traits. Previous studies have shown that black seeds have a very low germination rate under natural conditions, but exogenous GA₃ effectively enhanced the germination rate of black seeds. However, the physiological and molecular mechanisms underlying the effects of GA₃ on S. glauca black seeds are still unclear. In this study, transcriptomic profiles of seeds at different germination stages with and without GA₃ treatment were analyzed and compared, and the TTF, H₂O₂, O₂ ^-, starch, and soluble sugar contents of the corres
