Brassinosteroids are a group of over seventy steroid compounds whose discovery in lower and higher plant organisms created new possibilities growth control. The aim the work was to evaluate effect two brassinosteroids: brassinolide (BL) 24-epibrassinolide (24epiBL) as compared auxin rooting enhancer indole-3-butyric acid (IBA), on stem cuttings Thunberg’s barberry cultivars ‘Maria’ ‘Red Rocket’...

Abstract The objective of this work was to evaluate the effects brassinosteroid on chlorophyll a fluorescence parameters, SPAD index, and leaf succulence in young tomato (Lycopersicon esculentum) plants under salt stress. experimental design randomized complete block, 5×2 factorial arrangement - five levels water salinity (0.5, 1.5, 3.0, 4.5, 6.0 dS m-1) × two rates 24-epibrassinolide (0 10-6 m...

Brassinosteroids (BRs) are endogenous plant hormones and are essential for normal plant growth and development. MicroRNAs (miRNAs) of Arabidopsis thaliana are involved in mediating cell proliferation in leaves, stress tolerance, and root development. The specifics of BR mechanisms involving miRNAs are unknown. Using customized miRNA array analysis, we identified miRNAs from A. thaliana ecotype ...

The effect of 24-epibrassinolide (EBR) on glucosinolate biosynthesis in Arabidopsis thaliana was investigated in the present study by using mutants and transgenic plants involved in brassinosteroid (BR) biosynthesis and signal transduction, as well as glucosinolate biosynthesis. The results showed that EBR significantly decreased the contents of major aliphatic glucosinolates including glucoibe...

Color and other quality parameters of “Redglobe” grape (Vitis vinifera L.) berries were evaluated after treatment with brassinosteroid (BR) analogs. Three BRs analogs (24epibrassinolide, Triol, or Lactone) were applied at three concentrations (0.0, 0.4, or 0.8 mg·L−1), at the onset of veraison. A commercial formulation (B-2000 R ) was also applied, at a recommended rate of 0.06 mg·L−1. The test...
