Brassinosteroids (BRs) play important roles in many growth and developmental processes. BRs signal to regulate BR-INSENSITIVE1-ETHYL METHANESULFONATE-SUPPRESSOR1 (BES1) and BRASSINAZOLE-RESISTANT1 (BZR1) transcription factors (TFs), which, in turn, regulate several hundreds of transcription factors (termed BES1/BZR1-targeted TFs or BTFs) and thousands of genes to mediate various BR responses. Chromatin Immunoprecipitation followed by high-throughput sequencing (ChIP-seq) with BES1/BZR1 and BTFs is an important approach to identify BR target genes. In combination with RNA-sequencing experiments, these genomic methods have become powerful tools to detect BR target genes and reveal transcriptional networks underlying BR-regulated processes.

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

D047369 Chromatin Immunoprecipitation A technique for identifying specific DNA sequences that are bound, in vivo, to proteins of interest. It involves formaldehyde fixation of CHROMATIN to crosslink the DNA-BINDING PROTEINS to the DNA. After shearing the DNA into small fragments, specific DNA-protein complexes are isolated by immunoprecipitation with protein-specific ANTIBODIES. Then, the DNA isolated from the complex can be identified by PCR amplification and sequencing. Immunoprecipitation, Chromatin
