Summary: Peppermint has promising potential due to its high proportion of bioactive compounds, especially menthol. A randomized pot experiment showed that the application of 10(-6) M 24-epibrassinolide (EBL) improved the growth, physiology, essential oil content, stomatal behavior, and trichome development of three cultivars of peppermint. This level of EBL significantly increased shoot length, root length, chlorophyll content, P-N, essential oil content, essential oil yield, and menthol yield in the plants.

Summary: The treatment of 24-epibrassinolide (EBR) can maintain the glucosinolates content in broccoli and alleviate the decrease of glucosinolates by upregulating the genes involved in the glucosinolates biosynthesis pathway and activating the transcription factors in the brassinosteroids signal transduction pathway.

Summary: Drought stress is a major problem that negatively affects crop growth and development. Brassinosteroids, including EBR, play an important role in improving drought tolerance by enhancing enzymatic antioxidant defense system and osmoregulation. EBR application improves BR and IAA phytohormone content and upregulates genes related to their signaling pathways, thereby enhancing drought tolerance in crop plants.

Summary: This study evaluated the efficacy of chitosan functionalized with epibrassinolide coating in preserving the postharvest quality of late-harvested pomegranate fruit. The results showed that the CH + 10μM EBR treatment significantly delayed degradation processes, reduced weight loss, respiration, electrolyte leakage and decay, and maintained higher texture and total soluble solids compared to untreated fruit. This was attributed to the higher antioxidant content of the coated fruit.

Summary: Three aza-Bodipy donor molecules, Aza-Bthp, Aza-Sty, and Aza-Fhdt, have been synthesized, exhibiting broad panchromatic absorption and suitable energy levels for use in organic solar cells. Under optimized conditions, they achieved power conversion efficiencies of 2.44, 1.2, and 2.52 for Aza-Bthp, Aza-Fhdt, and Aza-Sty, respectively, when using PC70BM as an acceptor.

Summary: This study demonstrates the protective role of 5-aminolevulinic acid (ALA) and 24-epibrassinolide (EBL) on the growth of drought-stressed banana plants. Exogenous application of ALA or EBL can restore photosynthetic activity, increase productivity, and reduce oxidative damage under reduced irrigation. The study suggests the use of ALA or EBL at a concentration of 30 mg.L-1 to promote the growth and productivity of drought-stressed banana plants.

Summary: This study successfully prepared composite nanoparticles that can achieve sustained release of pesticides while accelerating the degradation of pesticide residues. The composite nanoparticles showed higher deposition on rice and increased pesticide utilization efficiency compared to conventional pesticides, resulting in stronger insecticidal effect and lower residual amount after 21 days.

Summary: Climate change is causing more frequent droughts, which hinder plant growth and productivity. Exogenous application of the plant growth regulator 24-epibrassinolide (EBR) shows promise in improving drought tolerance in Carapa guianensis trees. This study examines the effects of EBR on hydraulic traits, physiological responses, and metabolism in young C. guianensis exposed to drought. The results demonstrate that EBR treatment increases water potential, enhances CO2 fixation, improves stomatal performance, and stimulates antioxidant defenses, ultimately improving the drought tolerance of young C. guianensis plants.

Summary: This study investigates the formation of ectopic xylary elements (EXEs) in Arabidopsis thaliana and its response to the soil pollutant Cadmium (Cd). The results demonstrate that Brassinosteroids (BRs), specifically 24-epibrassinolide (eBL), play a role in promoting EXE formation and alleviating Cd stress. Furthermore, eBL induces a reversal of xylary identity and forms a protective barrier against Cd toxicity.
