Abstract Background Brassinosteroid-insensitive 1 suppressor (BRS1) is a serine carboxypeptidase that mediates brassinosteroid signaling and participates in multiple developmental processes Arabidopsis. However, little known about the precise role of BRS1 this context. Results In study, we analyzed transcriptional proteomic profiles Arabidopsis seedlings overexpressing found gene was involved b...
In order to investigate the effects of different levels of drought stress and application of brassinosteroid on some growth, physiological and biochemical characteristics of wild pear (Pyrus biossieriana Buhse) seedlings, an experiment was conducted in greenhouse in factorial form based on fully random pattern with three replications. Experimental treatments included different levels of drought...
Brassinosteroids are steroidal hormones essential for the growth and development of plants. Brassinolide, the most biologically active brassinosteroid, has a seven-membered lactone ring that is formed by a Baeyer-Villiger oxidation of its immediate precursor castasterone. Despite its potential key role in controlling plant development, brassinolide synthase has not been identified. Previous wor...
After feeding of 24-epi-castasterone to the cockroach Periplaneta americana an organ-specific epimerization of the brassinosteroid to 2,24-diepi-castasterone could be detected in female insects. The metabolite being observed only in the ovaries and not in the testes of the insect was identified by GC/MS in comparison with a synthesized authentic sample. Contrary, 24-epi-brassinolide is not meta...
Drought is one of the most important factors limiting crops growth and production and use of plant growth regulators to cope with water stress is of interest to many researchers. In order to study the effects of two plant growth regulators, brassinosteroid (BR) and salicylic acid (SA) on germination and growth of two wheat cultivars in water deficit conditions, a greenhouse experiment was desig...
The brassinosteroid-SIGNALING KINASE (BSK) belongs to the receptor-like cytoplasmic kinase XII subgroup. BSK1 regulates development and immunity in Arabidopsis. However, the function of rice (Oryza sativa) BSK1 is largely unknown. Here, we report that the expression level of OsBSK1-2 is induced after a chitin or fagellin22 (flg22) treatment. Silencing OsBSK1-2 in rice results in compromised res...
Since the isolation and characterization of dwarf1-1 (dwf1-1) from a T-DNA insertion mutant population, phenotypically similar mutants, including deetiolated2 (det2), constitutive photomorphogenesis and dwarfism (cpd), brassinosteroid insensitive1 (bri1), and dwf4, have been reported to be defective in either the biosynthesis or the perception of brassinosteroids. We present further characteriz...
Bri1-associated kinase 1 (BAK1)-interacting receptor-like kinase (BIR) proteins have been shown to play important roles in regulating growth and development, pathogen associated molecular pattern (PAMP)-triggered immunity (PTI) responses, and cell death in the model plant, Arabidopsis thaliana. We identified four BIR family members in tomato (Solanum lycopersicum), including SlBIR3, an ortholog...
