“…BR and GA are vital hormones in plant that influence various developmental processes, such as cell division, cell elongation, flowering, leaf senescence, and seed germination (Greenboim-Wainberg et al, 2005;Vriet et al, 2013;Fariduddin et al, 2014;Sakata et al, 2014;Hedden and Sponsel, 2015). BR and GA interact with each other at both biosynthesis and signaling levels to form a potential complex network Zhang et al, 2012).…”

“…This positive action is generally correlated with higher expression of stress marker genes, indicating that increased expression of stress responsive genes is responsible, at least in part, for the higher stress tolerance in BR-treated plants (Vardhini and Anjum 2015). In addition, it has been shown that application of BRs activates antioxidative pathways, including ROS-scavenging systems, as well as, non-enzymatic antioxidants, such as osmolytes like proline, glycine betaine, sorbitol, mannitol, and reduced glutathione, ascorbic acid that are needed for osmotic adjustment, stabilization of membranes, and ROS-scavenging (Fariduddin et al 2014). However, it is still unclear whether BRs, directly or indirectly, modulate the responses of plants to oxidative stress.…”

Brassinosteroids (BRs) are plant specific steroidal hormones that play diverse roles in regulating a broad spectrum of plant growth and developmental processes, as well as, in responding to various biotic and abiotic stresses. Extensive research over the years has established stress-impact-mitigating role of BRs and associated compounds in different plants exposed to various abiotic and biotic stresses, suggesting the idea that they may act as immunomodulators, thus opening new approaches for plant resistance against hazardous environmental conditions. In this research the characterization of the transcriptional response of 11 transcription factors (TFs) belonging to BRASSINAZOLE-RESISTANT 1 (BZR1) TF family of Zea mays L. was analyzed in seedlings subjected to different stress conditions. Being important regulators of the BR synthesis, BZR TFs might have stress resistance related activities. However, no stress resistance related functional study of BZR TFs has been reported in maize so far. In silico analyses of the selected 11 TFs validated the features of their protein domains, where the highest degree of similarity observed with recognized BZR TFs of rice and Sorghum bicolor. Additionally, we investigated the organ-specific expression of 11 ZmBZR in maize seedlings. Five of them did not show any transcript accumulation, suggesting that ZmBZR expression might be regulated in a manner dependent on plant developmental stage. For the remaining six ZmBZR, their ubiquitous expression in the whole plant indicates they could function as growth regulators during maize development. More importantly, in response to various stress conditions, the spatial transcript accumulation of all ZmBZR varies along the plant. All six ZmBZR showed up-regulation against N starvation, hypoxia and salt stress. On the contrary, heat stress clearly down-regulated gene expression of all ZmBZR analysed. Consistently with the expression results, the distribution of stress-related cis-acting elements in the promoter of these genes inferred that the maize BZR TFs might play some roles in regulating the expression of the corresponding genes in response to multifarious stresses. In conclusion, these data reveal that BZR TFs have stress signaling activity in maize, in addition to their confirmed role in regulating plant physiology and morphology.

“…Вместе с тем, механизмы стресс-протекторного, в том числе, и солезащитного действия стероидных фитогормонов в настоящее время изучены недостаточно. Кроме того, защитный эффект гормонов обычно оценивают при его совместном действии с повреждающим фактором [Fariduddin et al, 2014;Siddiqui et al, 2018]. Имеются немногочисленные работы, в которых предпринимаются попытки более фундаментального подхода при изучении гормональной регуляции физиологических процессов при стрессе у растений [Ефимова и др., 2016, 2018a; Кузнецов и др., 2016].…”

Abstract. The ability of brassinosteroids, such as brassinolide, 24-epibrassinolide and 28-homobrassinolide to increase the resistance of potato plants (Solanum tuberosum L.) to salt stress was investigated along with the possible mechanisms of their protective action. For the first time, the specificity of the protective effect of brassinosteroids from their chemical structure, the concentration of them and the duration of the exposure was established.
