The effect of applying brassinosteroids to seeds on growth, pigment levels and nitrate reductase activity of rice (Oryza sativa L.) plants grown on saline substratum was investigated. Brassinosteroids reduced the impact of salt stress on growth, considerably restored pigment levels and increased of nitrate reductase activity. 
Influence of Brassinosteroids on Wheat Plant (Triticum aestivum L.) Production under Salinity Stress Conditions I- Growth Parameters and Photosynthetic Pigments
Foliar application of BRs increased yield and yield attributes of treated plants and significantly overcome the depressive effect of saline irrigation water at all levels on crop productivity and photosynthetic pigments.
Effect of Crude Brassinosteroid extract on growth and biochemical changes of Gosssypium hirsutum L. and Vigna mungo L
Both the plants exhibited high percentage of vegetative growth such as shoot length, fresh weight, dry weight and leaf area on 3% of BR supplementation and among the concentration, 3% BRs caused maximum effect than the other tested concentrations.
Advances on exogenous applications of brassinosteroids and their analogs to enhance plant tolerance to salinity: A review
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.
Effect of Growth Factors on the Metabolism of Cucumber Crops Grown in a Greenhouse
The article represents a three-year study of the effect of bioactive substances as part of growth promoting factors on the course of physiological processes in cucumber crops when grown under
Effects of brassinosteroids on the plant responses to environmental stresses.
Seed priming with brassinolide improves lucerne (Medicago sativa L.) seed germination and seedling growth in relation to physiological changes under salinity stress
The results showed that germination percentage, germination index, and vigour index of lucerne seeds primed with brassinolide were significantly higher than those of the non-primed seeds under salinity stress in each variety, suggesting that primingLucerne seed with brass inolide at a suitable concentration can improve germination and seedling growth under high-saline soils.
Modulation of morpho-physiological traits of Leymus chinensis (Trin.) through exogenous application of brassinolide under salt stress.
Improvement of growth, development, osmolytes, chlorophyll contents and antioxidant enzymes in L. chinensis due to foliar applied brassinolide was found to be associated with BR-induced positive role in stress amelioration.
Amelioration of Lead Toxicity in Radish (Raphanus sativus L) Plants by Brassinolide
The present study was designed to evaluate the effect of lead (Pb) and combine effect of Pb with brassinolide (BL) on the growth, metabolite contents and enzyme activities in radish plants. Pb
Agricultural industry is subjected to enormous environmental constraints, particularly due to salinity and drought. We evaluated the role of silicon (Si) in alleviating salinity and drought induced
Methyl jasmonate alleviated salinity stress in soybean
It is revealed that MeJA counteracted the negative effects of NaCl stress on plant growth, chlorophyll content, leaf photosynthetic rate, leaf transpiration rate, and proline content.


Effect of brassinosteroids on salinity stress induced inhibition of seed germination and seedling growth of rice (Oryza sativa L.)
Brassinosteroids were found to reverse the inhibitory effect on germination and seedling growth of rice induced by salinity stress and were associated with enhanced levels of nucleic acids and soluble proteins.

This review examines the microchemical and molecular genetic analyses that have provided convincing evidence for an essential role of BRs in diverse developmental programs, including cell expansion, vascular differentiation, etiolation, and reproductive development.
Influence of spectral quality on the growth response of intact bean plants to brassinosteroid, a growth‐promoting steroidal lactone. I. Stem elongation and morphogenesis
Brassinosteroid partially overcame the natural inhibitory effects of CWF radiation on stem elongation and greatly stimulated accumulation of photosynthate in the treated internode, suggesting a possible mobilization role for BR in the intact plant.
Influence of spectral quality on the growth response of intact bean plants to brassinosteroid, a growth-promoting steroidal lactone. II. Chlorophyll content and partitioning of assimilate
Findings suggest a possible mobilization role of BR and establish the importance of adequate PPFD (and photosynthate) for maximum swelling and splitting response to brassinosteroid.
Brassinosteroids : steroidal plant hormones
The structure-activity relationship of brassinosteroids and the practical application of brassionosteroids in agricultural fields are studied.
The influence of salinity on the utilization of root anaplerotic carbon and nitrogen metabolism in tomato seedlings
Products of inorganic carbon incorporation in the roots of salinized plants provide an anaplerotic source of carbon for assimilation of reduced NO 3 - into amino acids, while in control plants the products were predominantly organic acids as part of mechanisms to maintain ionic balance in the cells and in the xylem sap.
A Role for Brassinosteroids in Light-Dependent Development of Arabidopsis
The Arabidopsis DET2 gene encodes a protein that shares significant sequence identity with mammalian steroid 5α-reductases, and brassinosteroids may constitute a distinct class of phytohormones with an important role in light-regulated development of higher plants.
Recent progress in brassinosteroid research
Brassinosteroid inclusion in the category of plant hormones is now widely accepted, and much more research into the effects of brassinosteroids can be expected in future.
Blockage of Brassinosteroid Biosynthesis and Sensitivity Causes Dwarfism in Garden Pea
The findings indicate that the lkb plants are BR-deficient mutants, probably as a consequence of a block in the BR biosynthetic pathway prior to the production of teasterone.
