The present investigation describes the effects of 24-epibrassinolide on plant growth, copper uptake and bioconcentration factor in the plants of Brassica juncea L. cv. PBR 91 under Cu metal stress. The study revealed that there was an improvement in the shoot emergence and plant biomass production under the influence of pre-germination treatment of 24-epibrassinolide (24-epiBL). In addition, 24-epiBL blocked copper metal uptake and accumulation in the plants. 
Amelioration of Mn toxicity by Brassinosteroids in Brassica juncea L.
It was observed that 28-homoBL reduced the toxicity of heavy metal on seedling growth by influencing the protein content and antioxidative enzyme activities.
24-epibrassinolide induced antioxidative defense system of Brassica juncea L. under Zn metal stress
24-EBL seed-presoaking treatment improved the plant growth in terms of increase in shoot length and mitigated the toxicity of Zn metal by increasing the number of leaves, thereby revealing stress-protective properties of the brassinolide.
Alleviation of Cadmium and Mercury Stress by Supplementation of Steroid Hormone to Raphanus sativus Seedlings
The present work was undertaken to study the effects of 24-epibrassinolide (24-EBL) on percent germination, growth (root length, shoot length, fresh weight and dry weight), lipid peroxidation, sodium
Role of Homobrassinolide and Salicylic Acid on the Vegetative Growth of Groundnut (Arachis hypogaea., L) Plants Subjected to Cadmium Stress
The present study was carried out to study the role of homobrassinolide (HomoBL) and salicylic acid (SA) on vegetative growth of groundnut (Arachis hypogaea., L.) wherein field experiments were
Isolation and characterization of 24-Epibrassinolide from Brassica juncea L. and its effects on growth, Ni ion uptake, antioxidant defense of Brassica plants and in vitro cytotoxicity
It was observed that pre-treatment of isolated 24-Epibrassinolide lowered the Ni ion uptake in plants and improved growth, and the amelioration of Ni toxicity was also observed by the activities of antioxidant enzymes.
Effects of 28-homobrassinolide on nickel uptake, protein content and antioxidative defence system in Brassica juncea
The effects of 28-homobrassinolide (HBL) on nickel uptake, protein content and activities of antioxidative enzymes were determined in the seedlings of Brassica juncea L. The seeds were treated with
Influence of 24-epibrassinolide on seedling growth and distribution of mineral elements in two maize hybrids
It was found that hybrids react differently to exogenously applied hormone, and find­ings suggest that maize hybrid seedlings treated with lower concentrations of 24-EBL could survive and be successful in polluted areas.


Effects of Brassmosteroids on Growth, Nodulation, Phytohormone Content and Nitrogenase Activity in French Bean Under Water Stress
Brassinosteroids in the unstressed plants increased root nodulation, ZR content and nitrogenase activity, and also ameliorated their stress-induced decline in the nodulated roots, and among the brassInosteroids, epibrassinolide was relatively more effective.
Brassinolide Amelioration of Aluminum Toxicity in Mungbean Seedling Growth
Results showed that BL had promoted growth of mungbean seedlings under Al stress, and the most significant promotive effect of BL on morphological traits and chlorophyll content seems to depend on the addressed traits, BL concentration, and Al stress.
Effects of 24-epibrassinolide on seed germination, seedling growth, lipid peroxidation, proline content and antioxidative system of rice (Oryza sativa L.) under salinity stress
24-epiBL treatment considerably alleviated oxidative damage that occurred under NaCl-stressed conditions and improved seedling growth in part under salt stress in sensitive IR-28 seedlings.

Brassinosteroids and lead as stimulators of phytochelatins synthesis in Chlorella vulgaris
The brassinosteroids showed a stronger stimulation of the synthesis of PC by the algal cell than the culture treated with lead alone and growth was very quick.
Blockade of heavy metals accumulation in Chlorella vulgaris cells by 24-epibrassinolide
In vitro stem elongation of sweet pepper in media containing 24-epi-brassinolide
It appears that EBR does not always act directly on stem elongation but may be an elicitor and/or an enhancer of elongation in concert with endogenous and other exogenously added growth regulators.
Effect of brassinolide on gene expression in elongating soybean epicotyls.
Two-dimensional gel analysis of in vitro translated mRNA is shown that a submicromolar concentration of BR alters the pattern of gene expression in elongating soybean epicotyls, suggesting that the molecular mechanism of BR-induced elongation is likely to differ from that of auxin- induced elongation in this system.
Copper toxicity in rice seedlings: Changes in antioxidative enzyme activities, H2O2 level, and cell wall peroxidase activity in roots
It appears that growth inhibition of root caused by Cu is associated with H2O2 dependent peroxidase-catalyzed formation of cross-linking among cell wall polymers.
