Glutamate decarboxylase (GAD) is an enzyme that catalyzes the production of gamma-amino butyric acid (GABA) from glutamate through a decarboxylation reaction. A full-length cDNA encoding glutamate decarboxylase (GmGAD1) was isolated from germinating soybean seeds (Glycine max [L.] Merr.). The GmGAD1
Immature embryos of soybean [Glycine max (L.) Merr., cvs. Beeson, Chippewa, Swift, and Tonica] ranging from globular to cotyledon stages were cultured in vitro. A variety of media consisting of 24 combinations of basic media salts, growth regulators, and carbon sources was tested in conjunction with
L-Canavanine, 2-amino-4-(guanidinooxy)butyric acid, and L-arginine incorporation into de novo synthesized proteins was compared in six organisms. Utilizing L-[guanidinooxy14C]canavanine and L-[guanidino14C]arginine at substrate saturation, the canavanine to arginine incorporation ratio was
An optimized regeneration and Agrobacterium-mediated transformation protocol based on whole cotyledonary node explants was developed in soybean (Glycine max) cultivar Zhong Huang 13. Adding 6-benzylaminopurine (BAP) in a germinating medium could significantly increase regeneration efficiency; the
Substantial evidence indicates that amino acid conjugates of indole-3-acetic acid (IAA) function in auxin homeostasis, yet the plant enzymes involved in their biosynthesis have not been identified. We tested whether several Arabidopsis thaliana enzymes that are related to the auxin-induced soybean
