(biochemistry)
Any of a class of plant hormones characterized as long-chain fatty-acid esters; brassins act to induce both cell elongation and cell division in leaves and stems.

To achieve this I will i) decipher the influence of the extracellular matrix on stem cell activity by cell type-specific modulation of matrix integrity; ii) decode the complex role of brassinosteroid hormones by tuning their activities during stem cell initiation; iii) record cell fate signatures by high-resolution 4-D expression maps for cambium subdomains; and iv) Identify novel signalling cascades connecting the extracellular matrix with underlying cells by forward genetics.
Unlike animal steroid hormones which are received by nuclear receptors, brassinosteroids are received by membrane localized leucine rich repeat receptor-like kinases (LRR RLK), such as BRASSINOSTEROID INSENSITIVE 1 (BRI1).
