Abstract: Abstract: There are lots of evidence that BRs biosynthesis deficiency or BRs sense disorder lead to plant dwarfism. In this paper we described the genes and dwarf mutations related to the BRs biosynthesis and signal transduction， by doing so， we expatiated on the relationship between plant dwarfism and BRs in molecular level. Then we discussed the mechanism of BRs promoting elongation.
Key words: brassinosteroids (BRs ); brassinlide (Bl); biosynthesis; signal transduction; XET (xyloglucan endotransglycosylase); dwarf mutant
