“…The culture of C. vulgaris exposed to metals shows that BRs prevent the loss of chlorophyll, sugar, and protein and improve the syntheses of phytochelatins (PC; Bajguz, 2000 , 2002 ). Moreover, it has been proved that brassinolide promotes the growth of mung bean seedlings under aluminum stress ( Abdullahi et al, 2003 ). In addition, EBL considerably increases the fresh mass of shoots and roots as well as chlorophyll content in mung beans under aluminum stress ( Ali et al, 2008a ).…”

Brassinosteroids (BRs) are a widespread group of plant hormones. These phytohormones play a crucial role in the regulation of growth and development of various plant species, and they demonstrate high biological activity. BRs are considered to demonstrate protective activity in the plants exposed to various stresses. Due to rapid industrialization and urbanization, heavy metals have become one of the most important plant stressors. In plants, accumulation of heavy metals beyond the critical levels leads to oxidative stress. However, BRs may inhibit the degradation of lipids, resulted from the overproduction of reactive oxygen species under stress conditions, and increase the activity of antioxidants. They also have the ability to promote phytochelatins synthesis.

“…A aplicação de 24-epibrassinolídeo incrementou o crescimento e induziu a síntese de clorofila em plântulas de Vigna radiata L. Wilczek, sob estresse por alumínio (ABDULLAHI et al, 2003;ALI et al, 2008). Da mesma forma, o 24-epibrassinolídeo também é reconhecido por restabelecer ou induzir a germinação e todas as características de crescimento em trigo e sorgo sob estresse hídrico (VARDHINI; , além de aumentar a tolerância das plântulas sob estresse por metais pesados como, cádmio em Brassica juncea L.

Salinity can be considered a limiting factor to the growth and development of plants to affect various physiological processes. The aim of this study was to determine the effect of 24 -epibrassinolide in emergence, seedling growth, leaf area and chlorophyll concentration in two cultivars of rice in salt stress condition. The study was conducted at the research laboratory of seeds and greenhouse of the Department of Botany UFPel. Rice seeds of cvs. BRS Bojurú tolerant to salinity and BRS Querência not tolerant, were soaked for two hours in water, 100 mMNaCl and 100 mMNaCl solutions supplemented with 24 -epibrassinolide at concentrations of 0.01, 0,1 and 1.0 mM and sown in expanded polypropylene tray. The experimental design was completely randomized with five treatments, two cultivars and four replications. Means were compared by Tukey test (p < 5 %), within each cultivar. In cv. BRS Querência 1 Dr as do PPG em Fisiologia Vegetal,

“…Al ions are capable of binding with lipid components of the plasma membrane [60] causing the rigidification of plasma membrane [61] and to DNA [62], and therefore, impairs cell division [58]. Al is reported to inhibit the plant growth [63], mainly that of root [64,65]. Besides this, Al also alters water relations [41], reduces stomatal opening, decreases photosynthetic activity and causes chlorosis and necrosis of leaves [58].…”

Soil contamination with heavy metals has become a worldwide problem, leading to the loss in agricultural productivity. Plants have a remarkable ability to take up and accumulate heavy metals from their external environment and it is well known that high levels of heavy metals affect different physiological and metabolic processes. Brassinosteroids are considered as the sixth class of plant hormones and they are essential for plant growth and development. These compounds are able of inducing abiotic stress tolerance in plants. In this paper, information about brassinosteroids and plant responses to heavy metal stress is reviewed.
