“…Furthermore, various plants respond to environmental stresses by activating enzymes, resulting in increased levels of allantoin and allantoate (Sagi et al, 1998). Recently, the constitutive accumulation of allantoin was shown to improve overall plant performance under stress by activating abscisic acid signaling pathways (Wang et al, 2012), and exogenous application mitigated oxidative damage symptoms (Watanabe et al, 2014).…”

“…So, for example, АОcatalyzes the last stages in biosynthesis of two phytohormones; oxidation of abscisic aldehyde up to abscisic acid and oxidation of indole-3-acetaldehyde up to indole-3-acetic acid (Walker-Simmons et al, 1989, and Koshiba et al, 1996). XDH takes part in a purine metabolism and also in biosynthesis of ureides in higher plants; ureides like urea, as "scavengers", could remove oxygen radicals, which are formed under stress conditions (Sagi et al, 1998) Aldehyde oxidase gene (AAO3) doesn't show any expression in bean plants but in chickpea we can observe an intense expression when molybdenum and nitrogen are added to plant irrigation water, (Tab.4).The most important isoformis AAO3,whichcatalyzes the oxidation of abscisicaldehyde to abscisicacid(ABA) in the last cytosolicstep of ABA synthesis. Due to the function of ABA in many aspects of plant growth and development, andin adaptation to a variety of abiotic stresses, AAO3-deficient plantswithreduced ABA levels are characterized by a high transpirationrate, reduced stress tolerance, and impairedseeddormancy (Seoand Koshiba, 2011in Bittner (2014).…”
