Exogenous gibberellic acid shortening after-ripening process and promoting seed germination in a medicinal plant Panax notoginseng.

ABSTRACT:

Background

Panax notoginseng (Burk) F.H. Chen is an essential plant in the family of Araliaceae. Its seeds are classified as a type of morphophysiological dormancy (MPD), and are characterized by recalcitrance during the after-ripening process. However, it is not clear about the molecular mechanism on the after-ripening in recalcitrant seeds.

Results

In this study, exogenous supply of gibberellic acid (GA₃) with different concentrations shortened after-ripening process and promoted the germination of P. notoginseng seeds. Among the identified plant hormone metabolites, exogenous GA₃ results in an increased level of endogenous hormone GA₃ through permeation. A total of 2971 and 9827 differentially expressed genes (DEGs) were identified in resp
