“…The application of exogenous BL enhanced the contents of proline and soluble sugar but did not influence the levels of soluble protein (Figure 4). In Triticum aestivum, a significant increase in proline content and soluble sugar was noticed after the application of BL, thus protecting plants from the adverse effects of salt toxicity (Talaat and Shawky, 2012;Yusuf et al, 2017). Our results indicated that exogenous BL can protect apple seedlings from osmotic stress mainly through the accumulation of proline and soluble sugar.…”

“…In cucumber, BL increases photosynthesis by increasing chlorophyll content (Yuan et al, 2012). The application of BL improves photosynthesis by positively regulating synthesis and the activation of rubisco enzyme, thus increasing the gaseous exchange parameters of plants under salt stress (Fariduddin et al, 2014;Yusuf et al, 2017). It can be inferred that exogenous BL improves the photosynthetic rate of the apple seedlings under salt stress mainly by increasing chlorophyll content, leaf area, stomatal conductance, and rubisco enzyme activity.…”

“…Reactive oxygen species (ROS) induced by salt stress is alleviated by antioxidant systems, including antioxidants and antioxidant enzymes (Tofighi et al, 2017;Wu et al, 2017). The accumulation of osmolytes, such as sorbitol, proline, and lycine, is critical to osmotic balance (Shahid et al, 2014;Yusuf et al, 2017). Maintaining homeostasis of Na + and K + in cells by activating Na + and K + transporters is vital for plant salt stress tolerance (Azhar et al, 2017).…”

Brassinolide (BL) mediates various physiological processes and improves plant tolerance to abiotic stresses. However, the effects and mechanism of exogenous BL on the salt tolerance of apple seedlings remain unclear. Herein, we investigated the role of BL in the salt stress response of Malus hupehensis Rehd., a widely grown apple rootstock. Saltstressed apple seedlings showed significant decline in chlorophyll content and photosynthetic rate, and the application of 0.2 mg/L exogenous BL alleviated salt stress and maintained photosynthetic capacity. Exogenous BL application can strengthen the activities of superoxide dismutase and catalase and thereby eliminates reactive oxygen species (ROS) production induced by salt stress and promote the accumulation of proline and soluble sugar, thus maintaining osmotic balance. Furthermore, exogenous BL application decreased Na + accumulation and increased K + content in shoots and roots under salt stress by regulating the expression levels of Na + (K +)/H + antiporter genes (MhNHXs). MhBZR1 and MhBZR2, which are the key transcription factors in the BR signal transduction pathway, can directly bind to the promoter of MhSOS1 and MhNHX4-1, respectively, and inhibit their expression. Our findings would provide a theoretical basis for analyzing the mechanism of exogenous BL application on the salt tolerance of apples.

“…In the case of two wheat Triticum aestivum cultivars (LOK-1 and 502), the application of EBL enhanced the sugar content. Moreover, the maximum rise in the content of sugar was detected in the plants treated with the combination of Al and salt stress and sprayed with EBL in LOK-1 (Yusuf et al 2017).…”

Aquatic organisms are exposed to many stressors, e.g., heavy metals. Brassinosteroids, a plant hormone group, can effectively stimulate plants to defend against the negative impact of a heavy metal. The present study was conducted with an aim to find out the influence of 24-epibrassinolide (EBL) on Acutodesmus obliquus treated with 0.01 and 500 μM of lead (Pb) ions during 7 days of cultivation. Pb has a toxic effect on algal cultures because it limits both the growth and development and induces oxidative stress. Simultaneously, 1 μM EBL was involved in protecting algal cells against the toxic effect of Pb. Despite the presence of Pb, EBL significantly increased the number of algal cells and their metabolite content (e.g., proteins, monosaccharides, chlorophylls, carotenes, and xanthophylls). Cultures treated concurrently with EBL and Pb were characterized by a reduction in their content of endogenous Pb, H 2 O 2 , and malondialdehyde. Also, EBL increased the activity of catalase, ascorbate peroxidase, superoxide dismutase, glutathione reductase, and the content of ascorbate and glutathione. EBL increased the phytochelatin synthase activity, thereby enhancing the production of phytochelatins accountable for both binding and detoxification of Pb. These results indicate the influence of EBL on the inhibitory effect of Pb in A. obliquus. These findings help to clarify the role of BRs in the algal adaptation to the prevailing stressful conditions.

“…Moreover, BRs induce oxidative stress tolerance by triggering the accumulation of apoplast H 2 O 2 which subsequently up regulates the antioxidant system (Fariduddin et al, 2014). On the other hand, exogenous application of EBL modified the activity of enzymes of proline metabolism (Yusuf et al, 2017) and it also increased the expression of various oxidative stress marker genes, although to different levels (Sharma et al, 2013). Thus, Vardhini and Anjum (2015) reviewed the reports on the role of BRs in the modulation of enzymatic and non-enzymatic components of antioxidant defense system in abiotic stressed plants.…”

Soil salinity is one of the abiotic stresses, which reduces plant growth and limits crop productivity. Brassinosteroids are considered as the sixth class of plant hormones and they have pleiotropic effects on plants, among them, they can protect plants under abiotic stresses and especially under salt stress. This paper reviews the information published during the last sixteen years related to the effects of brassinosteroids and their spirostanic analogs in plants submitted to saline stress when they are used by means of seed treatments, through the application of foliar sprays or by rooting media. Brassinosteroids stimulated salt stress tolerance in plants is associated to a decrease of oxidative damage generated by this stress and the interaction between brassinosteroids and other plant hormones, for example: abscisic acid, ethylene and salicylic acid.
