“…Under drought stress condition, plants accumulate high levels of oxidative stress molecules, including ROS (Farooq et al 2019), which could directly damage chloroplasts known as the most susceptible organelles to oxidative stress condition (Yamauchi 2018). Our results indicated that the reduction of chlorophyll contents found in both nano-Cu o priming and water-treated groups during drought (Table 1), which may help plants allocating energy and maintain ROS production resulted from photosynthesis to adapt to drought (Casimiro and Arrabaça 2015;Gururani et al 2015;Huang et al 2019;Regier et al 2015;Wang et al 2018).…”

Abiotic stresses, including drought, detrimentally affect the growth and productivity of many economically important crop plants, leading to significant yield losses, which can result in food shortages and threaten the sustainability of agriculture. Balancing between plant growth and stress responses is one of the most important characters for agricultural application to maximize plant production. In this study, we initially report that copper nanoparticle priming positively regulates drought stress responses in maize. The copper nanoparticle priming plants displayed enhanced drought tolerance indicated by their higher leaf water content and plant biomass under drought as compared with water-treated plants. Moreover, our data showed that the treatment of copper nanoparticle on plants increased anthocyanin, chlorophyll and carotenoid contents compared to water-treated plants under drought stress conditions. Additionally, histochemical analyses with nitro blue tetrazolium and 3,3'-diaminobenzidine revealed that reactive oxygen species accumulation of priming plants was decreased as a result of enhancement of reactive oxygen species scavenging enzyme activities under drought. Furthermore, our comparative yield analysis data indicated applying copper nanoparticle to plant increased total seed number and grain yield under drought stress conditions. Our data provided the evidences that copper nanoparticle regulates plant protective mechanisms associated with drought tolerance, which is a promising approach for the production of drought tolerant crop plants.

“…We previously reported that exogenous Z‐3‐HAC stimulated the protective effects of the antioxidant system in protecting the photosystem (Tian et al ). In this study, we showed that Z‐3‐HAC not only enhanced the Pn but also increased the SPAD value, shoot biomass and plant height in peanut seedlings under salinity stress conditions (Table ), suggesting that Z‐3‐HAC might help to enhance the light use efficiency and CO 2 assimilation in peanut leaves under salinity conditions (Paul and Pellny , Guo et al , Farooq et al ). Notably, the application of Z‐3‐HAC did not affect these physiological parameters under normal growth conditions, which was consistent with other growth‐regulating substances, such as melatonin (Chen et al ), silicon (Zhu et al ) and sodium selenate (Subramanyam et al ).…”

“…In this paper, the importance of non‐enzymatic antioxidants, such as AsA and GSH, was further demonstrated. In the AsA‐GSH cycle, there is a close relationship between the activities of GR, MDHAR and DHAR and the metabolism of reactive oxygen species (ROS; Mittler et al , Noctor et al , Farooq et al ). As shown in Fig.…”

Green leaf volatiles (GLVs) are released by plants when they encounter biotic stress, but their functions in the response to abiotic stress have not been determined. We have previously shown that exogenous application of (Z)-3-hexeny-1-yl acetate (Z-3-HAC), a kind of GLV, could alleviate salt stress in peanut (Arachis hypogaea L.) seedlings; however, notably little is known concerning the transcription regulation mechanisms of Z-3-HAC. In this study, we comprehensively characterized the transcriptomes and physiological indices of peanut seedlings exposed to Z-3-HAC and/or salt stress. Analysis of transcriptome data showed that 1420 genes were upregulated in the seedlings primed with Z-3-HAC under salt stress compared with the non-primed treatment. Interestingly, these genes were significantly enriched in the photosynthetic and ascorbate metabolism-related categories, as well as several plant hormone metabolism pathways. The physiological data revealed that Z-3-HAC significantly increased the net photosynthetic rate, SPAD value, plant height and shoot biomass compared with the non-primed peanut seedlings under salt stress. A significantly higher ratio of K + :Na + , reduced-to-oxidized glutathione (GSH:GSSG), and ascorbate-to-dehydroascorbate (AsA:DHA) were also observed for the plants primed with Z-3-HAC compared with the salt stress control. Meanwhile, Z-3-HAC significantly increased the activity of enzymes in the AsA-GSH cycle. Taken together, these results highlight the importance of Z-3-HAC in protecting peanut seedlings against salt stress by affecting photosynthesis, cellular redox homeostasis, K + :Na + homeostasis, and phytohormones.

“…These molecules are of paramount importance in the plant immunity system playing several roles to impede fungal invasion (Rio et al , Lehmann et al , Camejo et al ). But, a disruption in their homeostasis leads to oxidative stress that would eventually disrupt plant growth and development (Czarnocka and Karpiński , Farooq et al ). Bhar et al () reported in chickpea an accumulation of ROS and a downregulation of key photosynthetic genes together with reduced rates of photosynthesis and growth under infection with F. oxysporum .…”

Phytopathogen infection alters primary metabolism status and plant development. The alternative oxidase (AOX) has been hypothesized to increase under pathogen attack preventing reductions, thus optimizing photosynthesis and growth. In this study, two genotypes of Medicago truncatula, one relatively resistant (Jemalong A17) and one susceptible (TN1.11), were infected with Fusarium oxysporum and Rhizoctonia solani. The in vivo foliar respiratory activities of the cytochrome oxidase pathway (COP) and the alternative oxidase pathway (AOP) were measured using the oxygen isotope fractionation. Gas exchange and photosynthesis‐related parameters were measured and calculated together with antioxidant enzymes activities and organic acids contents. Our results show that the in vivo activity of AOX (valt) plays a role under fungal infection. When infected with R. solani, the increase of valt in A17 was concomitant to an increase in net assimilation, in mesophyll conductance, to an improvement in the maximum velocity of Rubisco carboxylation and to unchanged malate content. However, under F. oxysporum infection, the induced valt was accompanied by an enhancement in the antioxidant enzymes, superoxide dismutase (SOD; EC1.15.1.1), catalase (CAT; EC1.11.1.6) and guaiacol peroxidase (GPX; EC1.11.1.7), activities and to an unchanged tricarboxylic acid cycle intermediates. These results provide new insight into the role of the in vivo activity of AOX in coordinating primary metabolism interactions that, partly, modulate the relative resistance of M. truncatula to diseases caused by soil‐borne pathogenic fungi.
