Arabidopsis brassinosteroid signaling pathway.
Plants control their size through the action of several phytohormones. One class of growth-promoting hormones is the brassinosteroids (BRs), the polyhydroxylated steroid hormones of plants. Here, we present the Arabidopsis-specific proteins that are the founding members of key BR signaling pathway components found in all plants. The genetic studies that identified these components are unique to...
متن کاملMultiple mechanisms modulate brassinosteroid signaling.
Brassinosteroids are essential hormones for plant growth and development. Genetic studies have identified key components of the BR signaling pathway, including the cell-surface receptor kinases that perceive BR, an intracellular kinase and a phosphatase, and nuclear transcription factors. Subsequent biochemical studies have revealed many details about signaling events from BR perception at the ...
متن کاملBrassinosteroid Signaling: Novel Downstream Components Emerge
Continued genetic screening and analysis of Arabidopsis mutants has extended our view of brassinosteroid signaling beyond hormone perception to downstream events involving a negative cytoplasmic regulator and nuclear localized positive activators of the brassinosteroid response.
متن کاملInterdependency of Brassinosteroid and Auxin Signaling in Arabidopsis
How growth regulators provoke context-specific signals is a fundamental question in developmental biology. In plants, both auxin and brassinosteroids (BRs) promote cell expansion, and it was thought that they activated this process through independent mechanisms. In this work, we describe a shared auxin:BR pathway required for seedling growth. Genetic, physiological, and genomic analyses demons...
متن کاملBRI1/BAK1, a Receptor Kinase Pair Mediating Brassinosteroid Signaling
The Arabidopsis BAK1 (BRI1 Associated receptor Kinase 1) was identified by a yeast two-hybrid screen as a specific interactor for BRI1, a critical component of a membrane brassinosteroid (BR) receptor. In yeast, BAK1/BRI1 interaction activates their kinase activities through transphosphorylation. BAK1 and BRI1 share similar gene expression and subcellular localization patterns and physically as...
