“…The two BRs at 3.0µM concentration caused a considerable increase in seedling growth even under stress and restored the growth to the level of unstressed control seedlings. It was shown that brassinosteroids relieved the salinity-induced inhibition of seed germination and seedling growth in barley (Kulaeva et al 1991) and rice (Anuradha and Rao 2001). Similarly, brassinosteroids improved the percentage of seed germination and seedling growth in sorghum under osmotic stress (Vardhini and Rao 2003).…”

“…Epibrassinolide was found to increase drought tolerance in wheat (Nilovskaya et al 2001). BRs developed resistance to low temperature in maize (He et al 1991) and rice (Kamuro and Takaysuto 1991), and increased tolerance to high temperature in wheat (Kulaeva et al 1991). The increase in thermotolerance in Brassica napus seedling by epibrassinolide was associated with accumulation of heat shock proteins (Dhaubhadel et al 1999).…”

The effect of 24-epibrassinolide and 28-homobrassinolide on seed germination and seedling growth of radish (Raphanus sativus L.) was studied under cadmium toxicity. The impact of brassinosteroids (BRs) on free proline levels and the activity of antioxidant enzymes catalase (CAT; EC 1.11.1.6), peroxidase (POD; EC 1.11.1.7), superoxide dismutase (SOD; EC 1.15.1.1), ascorbic peroxidase (APOX; EC 1.11.1.11) and guaiacol peroxidase (GPX; EC 1.11.1.7) in radish seedlings under Cd toxicity was evaluated. The effect of BRs on the activity of ascorbic acid oxidase (AAO; EC 1.10.3.3) and lipid peroxidation in radish seedlings challenged with Cd stress was also investigated. BRs supplementation alleviated the toxic effect of the heavy metal and increased the percentage of seed germination and seedling growth. Out of the two substances, HBL was found to be more effective than EBL in stress alleviation. HBL (3µM) alleviated the toxic effect of the heavy metal and increased the percentage of seed germination by 57% over Cd and 20% over unstressed control. Similarly supplementation of HBL (3µM) caused an increase of 156%, 78% and 91% in length, fresh weight and dry weight of seedling, respectively, over Cd treatment alone. The amelioration of seedling growth by BRs under metal toxicity was associated with enhanced levels of free proline. The activities of antioxidant enzymes CAT, SOD, APOX and GPX were increased in the seedlings from treatments with Cd along with BRs. Brassinosteroid treatment reduced the activity of POD and AAO in heavy metal stressed seedlings. Lipid peroxidation induced by Cd was found reduced with the supplementation of BRs. The results obtained in the study clearly indicated the ameliorative influence of brassinosteroids on the inhibitory effect of Cd toxicity.

“…Kartal et al (2009) reported that 28-HBL treatment significantly increased protein content in barley seedlings. Kulaeva et al (1991) reported that BRs can protect cereal leaf cells from heat shock stress. Pre-treatment with both 22S, 23S-homoBL and 24-EBL activated total protein synthesis and de novo synthesis of different polypeptides when wheat leaves were heat-shocked by subjecting them to 40°C as well as normal temperatures.…”

“…Increase in protein content as a result of EBL application could have been due to the BR-modulated synthesis of polypeptides and proteins under normal as well as environmental stress conditions (Kulaeva et al 1991;Clouse & Sasse 1998;Dhaubhadel et al 2002). Additionally, the BR-mediated alteration in proteins and enzymes by regulation of transcription and translation (Bajguz 2000) was found to be one of the reasons behind the enhanced protein and amino acid contents as a result of EBL seed treatment.…”

Pesticides are applied to protect crops from a variety of insect pests but their application cause toxicity to plants that results, among others, in reduction of protein as well as amino acid contents. The present study is aimed at observing the effect of seed pre-soaking with 24-epibrassinolide (EBL) on the protein and amino acid content in the leaves of Brassica juncea L. grown in soil that is amended with pesticide imidacloprid (IMI). Soil amendment with IMI resulted in a decrease in the contents in leaves of total proteins and 21 amino acids studied. Seed soaking with 100 nM of EBL resulted in the recovery of total protein as well as amino acid contents in leaves, when compared with plants grown in only IMI amended soils.
