Brassinosteroid signal transduction: clarifying the pathway from ligand perception to gene expression.
Recent genetic screens for novel components of brassinosteroid signaling have revealed proteins with cell surface, cytoplasmic, and nuclear localization that function as either positive activators or negative regulators of the brassinosteroid response. Initial microarray experiments have expanded the number of known brassinosteroid-regulated genes, providing a useful resource for better underst...
متن کاملBrassinosteroid signal transduction--choices of signals and receptors.
Small signaling molecules that mediate cell-cell communication are essential for developmental regulation in multicellular organisms. Among them are the steroids and peptide hormones that regulate growth in both plants and animals. In plants, brassinosteroids (BRs) are perceived by the cell surface receptor kinase BRI1, which is distinct from the animal steroid receptors. Identification of comp...
متن کاملThe ethylene signal transduction pathway in plants.
Ethylene (C2H4), the chemically simplest plant hormone, is among the best-characterized plant growth regulators. It participates in a variety of stress responses and developmental processes. Genetic studies in Arabidopsis have defined a number of genes in the ethylene signal transduction pathway. Isolation of two of these genes has revealed that plants sense this gas through a combination of pr...
متن کاملSignal transduction pathway of TonB-dependent transporters.
Transcription of the ferric citrate import system is regulated by ferric citrate binding to the outer membrane transporter FecA. A signal indicating transporter occupancy is relayed across the outer membrane to energy-transducing and regulatory proteins embedded in the cytoplasmic membrane. Because transcriptional activation is not coupled to ferric citrate import, an allosteric mechanism under...
متن کاملArabidopsis 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...
