Abstract
Seed germination is associated with grain yield and quality in crop production. Gibberellic acid (GA) serves as a major phytohormone in the promotion of seed germination. It is synthesized in the embryos and transmitted to the aleurone layers, where GA triggers the synthesis and secretion of a set of hydrolases, especially α-amylase. Subsequently, the storage nutrients such as starch in the endosperm are digested by these hydrolases and absorbed by the embryo to sustain seed germination and early seedling establishment (Kaneko et al, 2002). The detailed GA biosynthesis process has been well studied and thoroughly reviewed in several literatures (Sakamoto et al, 2004; Reinecke et al, 2013). ...
