“…Plants are frequently damaged by insects, many of which are herbivores, eliciting a rapid increase in endogenous JA levels [166]. Interestingly, when plants are sprayed with JA, plant secondary metabolites and systemic resistance are induced to avoid the damage by insects, although JA itself is non-toxic to insects [167,168].…”

As sessile organisms, plants must tolerate various environmental stresses. Plant hormones play vital roles in plant responses to biotic and abiotic stresses. Among these hormones, jasmonic acid (JA) and its precursors and derivatives (jasmonates, JAs) play important roles in the mediation of plant responses and defenses to biotic and abiotic stresses and have received extensive research attention. Although some reviews of JAs are available, this review focuses on JAs in the regulation of plant stress responses, as well as JA synthesis, metabolism, and signaling pathways. We summarize recent progress in clarifying the functions and mechanisms of JAs in plant responses to abiotic stresses (drought, cold, salt, heat, and heavy metal toxicity) and biotic stresses (pathogen, insect, and herbivore). Meanwhile, the crosstalk of JA with various other plant hormones regulates the balance between plant growth and defense. Therefore, we review the crosstalk of JAs with other phytohormones, including auxin, gibberellic acid, salicylic acid, brassinosteroid, ethylene, and abscisic acid. Finally, we discuss current issues and future opportunities in research into JAs in plant stress responses.

“…ROS in plant cells is a double edged sword, which damages cells at higher concentrations, while acting as a signal molecule at lower concentrations. ROS have very important roles in plant cell cycle regulation [6] and programmed cell death [7], and may interact with other signaling molecules, including salicylic acid [8], jasmonic acid, ethylene [9], NO [10], and Ca 2+ [11]. The interaction of ROS and ethylene has been reported in rice under salt stress [12].…”

Salinity is an issue impairing crop production across the globe. Under salinity stress, besides the osmotic stress and Na+ toxicity, ROS (reactive oxygen species) overaccumulation is a secondary stress which further impairs plant performance. Chloroplasts, mitochondria, the apoplast, and peroxisomes are the main ROS generation sites in salt-stressed plants. In this review, we summarize ROS generation, enzymatic and non-enzymatic antioxidant systems in salt-stressed plants, and the potential for plant biotechnology to maintain ROS homeostasis. Overall, this review summarizes the current understanding of ROS homeostasis of salt-stressed plants and highlights potential applications of plant nanobiotechnology to enhance plant tolerance to stresses.

“…Intervention factors such as plant hormones and nanomaterials play a vital role in plant defense against insect pests [7]. Qi et al showed jasmonic acid (JA) and ethylene contents were increased by Melon aphid infestation, which enhanced the resistance of cucumber plants to aphids [8]. Pawel et al demonstrated that luteolin, quercetin and apigenin in winter triticale can reduce hydrogen peroxide and superoxide radical concentration, protecting the winter triticale from the infestation of Sitobion avenae F and beetles [9].…”

Aphids are one of the most destructive insects in many cultivated plants including wheat, which can cause significant yield loss and damage the quality of agricultural products. Therefore, it is essential to control the occurrence of aphids during wheat growth. Previous studies reported the alterations in the resistance of wheat to pests induced by several external factors such as nutrients in soils and nano-carbonaceous materials. In this study, nanoselenium (nano-Se) was sprayed on wheat leaves at several concentration levels (1.0, 5.0, and 20 mg/L). Nano-Se (5.0 mg/L) could significantly reduce Sitobion avenae number (36%) compared with the control. The foliar application of nano-Se was found to enhance the antioxidation capacity by reducing MDA concentration and increasing GSH-Px, CAT, GSH, Pro and VE concentrations. Phenylpropane pathway was activated after the application of nano-Se, with significantly increasing apigenin and caffeic acid concentrations. The highlevel expression of the related genes (TaBx1A, TaBx3A, TaBx4A, TaASMT2, and TaCOMT) induced the increasing melatonin concentration by 88.6% and DIMBOA concentration by 64.3%. Different ratios of the secondary metabolites to nano-Se were conducted to examine the effects on wheat resistance to the Sitobion avenae.The results revealed the combination of nano-Se and melatonin can achieve the best overall performance by reducing the Sitobion avenae infection by 52.2%. The results from this study suggest that the coordinative applications nano-Se and melatonin combination could be more effectively improve the wheat resistance to aphids via promotion of volatile organic compound synthesis and modulation in phenylpropane and indole metabolism pathways.
