Exogenous application of brassinosteroid offers tolerance to salinity by altering stress responses in rice variety Pusa Basmati-1

Role of Exogenous 24-Epibrassinolide in Enhancing the Salt Tolerance of Wheat Seedlings

“…In this present study, salt stress significantly increased proline content in leaves and roots of wheat seedlings compared with CK (Figure 2A). Proline, under stress conditions acts as osmoprotectant, membrane stabilizer and ROS scavenger (Sharma et al, 2013;Zhang et al, 2013). These results were in agreement with the present study in which it has been observed that Spray of EBR increased the proline ( Figure 2A) and protein content ( Figure 2B), thus resulted in an increase in the ability of tolerance to NaCl.…”

“…Salt stress significantly decreased the total chlorophyll, chl a, chl b and carotenoids concentrations in leaves of wheat seedlings compared to CK (Table 2). Similarly, Sharma et al (2013) indicated that NaCl stress caused a significant reduction in the chlorophyll concentration.…”

“…All of these results indicated the importance of BRs in protection against stress-induced deleterious effects. Although some studies demonstrated that BRs could alleviate salinity toxicity (Sharma et al, 2013;Derevyanchuk et al, 2015), the mechanisms of EBR action on salt tolerance in plants are still far from being completely understood.…”

“…Recently, wheat salt-responsive proteins or the molecular mechanisms of salt tolerance in wheat (Li et al, 2013) were evidenced. Many studies demonstrated that BRs could enhance salt tolerance in multiple plants, such as rice (Sharma et al, 2013), strawberry (Karlidag et al, 2011) and Arabidopsis thaliana (Derevyanchuk et al, 2015), but limited information is available on the role of brassinosteroids (BRs) in response of wheat plants to salt stress. Therefore, this experiment focuses on the effect of the exogenous application of 24-EBR as a foliar spray on the plant growth, some physiological parameters and chemical content of wheat plants under saline conditions, and determines the mechanism of the application of exogenous 24-EBR could alleviate salinity toxicity and increase salt-tolerance of wheat plants.…”

Effects of 2,4-epibrassinolide on photosynthesis and Rubisco activase gene expression in Triticum aestivum L. seedlings under a combination of drought and heat stress

“…As a potent plant growth regulator, EBR is used to increase the growth and yield of important agricultural crops (Khripach et al 2000). It can also enhance plant tolerance to a variety of abiotic and biotic stresses (Xia et al 2009a, b;Sharma et al 2013;Xi et al 2013). For example, EBR application ameliorates the stress-induced inhibition of photosynthesis in tomatoes and cucumbers (Ogweno et al 2008;Yu et al 2004).…”
