Abstract

The participation of salicylate (SalA), gallate (GalA), and benzoate (BenA), in various physiological and biochemical processes in the plant under conditions of boron excess (BE), is largely unknown. The relationship between phenolic acids (PhAs) and regulation of antioxidant enzymes and B forms has been studied in the alleviation of oxidative stress caused by BE within the tomato callus. Tomato calli were subjected to BE (2 mM) in the absence or presence of three levels of BenA, GalA and SalA. The results demonstrated that different levels of PhAs attenuated the oxidative stress of BE by reducing hydrogen peroxide, B accumulation, and lipoxygenase activity (LOX) activity, and the moderate level was the most effective. Phenolic acid treatments reduced the stimulatory effects of BE on catalase (CAT) and superoxide dismutase (SOD) activity. Similarly, BenA and GalA increased the effect of BE stimulation on the activities of ascorbate peroxidase (APX) and peroxidase (POD), while SalA decreased these impacts on both enzymes. The results highlight that PhAs perform an important function in alleviating BE stress in tomato calli by regulating antioxidant enzymes and forms of B accumulation. This research supplies new viewpoints for strategies associated with BE tolerance in tomato plants and therefore can be employed as plant growth stimulators.
