What is the role of gibberellins (GAs) in the germination of Lomatogonium rotatum seeds?

Label:chem

Topic
Gibberellins (GAs) are essential phytohormones that regulate seed dormancy release and germination. Lomatogonium rotatum is a traditional medicinal plant whose seed germination is often hindered by physiological dormancy. Exogenous GA3 treatment has been shown to improve germination rates in various plant species by antagonizing abscisic acid (ABA) signaling and activating GA-responsive pathways.
Answer
Exogenous GA3 treatment significantly improves the germination rate, vigor index, and other germination traits of Lomatogonium rotatum seeds. It promotes seed germination by activating GA-responsive pathways and alleviating the inhibitory effects of ABA, thus initiating cell elongation and metabolic reactivation.
