Brassinosteroid signaling in plants [PDF]
Trends in Endocrinology and Metabolism, 2001 In animals and humans, steroid hormones (SHs) regulate gene transcription via the binding of nuclear receptors. In addition, rapid nongenomic effects of steroids occur and appear to be mediated by plasma-membrane receptors. Plants also use steroids as signaling molecules. These brassinosteroids (BRs) show structural similarity to the SHs of vertebrates

Progress in the analysis of brassinosteroids
Chinese Journal of Chromatography, 2011Brassinosteroids have been considered as a class of plant hormones with high activity. However, the complex matrix of the plant samples and the ultra-trace level of naturally occurring brassinosteroids make their separation and determination very difficult.

Brassinosteroid‐Promoted Growth [PDF]
Plant Biology, 2005 Abstract: Brassinosteroids (BRs) are highly potent growth‐promoting sterol derivatives. BR‐deficient or BR‐insensitive mutants display dwarfism. Whole plants and excised tissues have been used to analyse the mechanisms involved in BR‐promoted growth.

Brassinosteroids in Arabidopsis thaliana
Phytochemistry, 1998From the seeds and siliques of Arabidopsis thaliana, six brassinosteroids, brassinolide, castasterone, typhasterol, 6-deoxocastasterone, 6-deoxotyphasterol and 6-deoxoteasterone, were identified by GC-mass spectrometry or GC-selected ion monitoring. As the occurrence of castasterone, typhasterol, 6-deoxocastasterone and 6-deoxotyphasterol in the shoots

Plants grow on brassinosteroids
Current Opinion in Plant Biology, 2011Brassinosteroids (BRs) are plant steroid hormones known mainly for promoting organ growth through their combined effect on cell expansion and division. In addition, BRs regulate a broad spectrum of plant developmental and physiological responses, including plant architecture, vascular differentiation, male fertility, flowering, senescence ...

Biosynthesis and Metabolism of Brassinosteroids [PDF]
Annual Review of Plant Biology, 2003 Brassinosteroids (BRs) are steroid hormones that regulate the growth and development of plants. Detailed study of the biosynthesis of brassinolide, a C28BR, revealed that two parallel routes, the early and late C-6 oxidation pathways, are connected at multiple steps and also are linked to the early C-22 oxidation pathway. Thus, BR biosynthetic pathways

Brassinosteroid Signaling Pathway
Science's STKE, 2006Plant growth is regulated by an intricate network of hormonal signaling pathways. These small-molecule hormones cause changes in gene expression that are associated with cell expansion and division and changes in development. Paradoxically, six of these hormones appear to have largely overlapping functions, yet the loss of response to any ...

The brassinosteroid chemical toolbox
Current Opinion in Plant Biology, 2014Chemical biology approaches have been instrumental in understanding the mode of action of brassinosteroids, a group of plant steroid hormones essential for plant development and growth. The small molecules used for such approaches include inhibitors of biosynthetic enzymes and signaling components.

Genomic Brassinosteroid Effects
Journal of Plant Growth Regulation, 2003Detailed analysis of brassinosteroid (BR)-regulated genes can provide evidence of the molecular basis of BR effects. Classical techniques (such as subtractive cDNA cloning) as well as cDNA and oligonucleotide microarrays have been applied to identify genes which are upregulated or downregulated after BR treatment or are differently expressed in BR ...

Biosynthesis and metabolism of brassinosteroids [PDF]
Physiologia Plantarum, 1997 Natural brassinosteroids so far identified from various plant species include biosynthetic congeners of brassinolide, such as cathasterone, teasterone, 3‐dehydroteasterone, typhasterol and castasterone as well as another series of 6‐deoxoteasterone, 3‐dehydro‐6‐deoxoteasterone, 6‐deoxotyphasterol and 6‐deoxocastasterone.
