Analysis of Herbivore Stress- and Phytohormone-Mediated Urease Expression in Soybean (Glycine max)

Ureases catalyze the hydrolysis of urea into ammonia and carbon dioxide and, thus, are involved in the metabolism and bioavailability of nitrogen. Ureases occur in plants, fungi, and bacteria. In plants, besides their enzymatic activity, ureases as proteins play a role in defense against insect and phytopathogenic fungi. Little is known about the regulation of urease in plants under stress and whether or not phytohormones may be involved. In...
