Application

Brassinazole has been used in phenotype analyses to detect morphological changes in G-protein β subunit agb1 mutants.

Packaging

5, 25 mg in glass bottle

Biochem/physiol Actions

Brassinazole induces dwarfism and morphological changes in Arabidopsis, which results in similarity with brassinosteroid deficient mutants. These changes were neutralized by brassinolide treatment, indicating that brassinazole leads to brassinolide deficiency in Arabidopsis.
Brassinazole is an inhibitor of the biosynthesis of brassinosteroids, steroid hormones essential for plant growth and development. It has been used to study brassinosteroids function.

Screening for brassinosteroid (BR) biosynthesis inhibitors was performed to find chemicals that induce dwarfism in Arabidopsis, mutants that resembled BR biosynthesis mutants that can be rescued by BR. Through this screening experiment, the compound brassinazole was selected as the most...

Root developmental plasticity enables plants to adapt to limiting or fluctuating nutrient conditions in the soil. When grown under nitrogen (N) deficiency, plants develop a more exploratory root system by increasing primary and lateral root length. However, mechanisms underlying this...

Six subspecies of hexaploid wheat (Triticumaestivum) have been identified, but the origin of Indian dwarf wheat (Triticum sphaerococcum), the only subspecies with round grains, is currently unknown. Here, we isolated the grain-shape gene Tasg-D1 in Tsphaerococcum via positional cloning. Tasg-D1...
