Previous research also established a significant correlation between seed...

Phytic acid (myo-inositol-1,2,3,4,5,6-hexakisphosphate) is the primary storage component of phosphorus in plant seeds. The first step in phytic acid biosynthesis is the de novo synthesis of myo-inositol, which is catalyzed by the enzyme D-myo-inositol 3-phosphate synthase (MIPS EC 5.5.1.4). Previous work detected four MIPS genes in soybean (Glycine...

This study explored the feasibility of near-infrared (NIR) quantitative and qualitative models for soybean inorganic phosphorus (Pi), which is complementary to phytic acid, a component of nutritional and environmental importance. Spectra, consisting of diffuse reflectance (1100-2500 nm) of ground meal and single-bean transmittance (600-1900 nm) of...

Soybean [Glycine max (L.) Merr.] seed phosphorus is stored primarily as phytic acid, a form in which it is unavailable to monogastric mammals and birds.
