Lychnis viscaria increases the disease resistance of surrounding plants. Įxtract from the plant Lychnis viscaria contains a relatively high amount of Brassinosteroids. Can provide some protection to plants during chilling and drought stress.Acceleration of senescence in dying tissue cultured cells delayed senescence in BR mutants supports that this action may be biologically relevant.Is necessary for pollen elongation for pollen tube formation.Promotion of vascular differentiation BR signal transduction has been studied during vascular differentiation.It has an unclear role in cell division and cell wall regeneration.Promotion of cell expansion and cell elongation works with auxin to do so.Hormonal activity īRs have been shown to be involved in numerous plant processes: Experiments have shown that long distance transport is possible and that the flow is from the base to the tips (acropetal), but it is not known if this movement is biologically relevant.

One well-supported hypothesis is that all tissues produce BRs, since BR biosynthetic and signal transduction genes are expressed in a wide range of plant organs, and short distance activity of the hormones also supports this. The sites for BR synthesis in plants have not been experimentally demonstrated.

The biosynthetic pathway was elucidated by Japanese researchers and later shown to be correct through the analysis of BR biosynthesis mutants in Arabidopsis thaliana, tomatoes, and peas. The BR is biosynthesised from campesterol.
