Summary

Go to the top of the page Help

Gene symbol: ARR7
Gene description: response regulator 7
Primary source: Araport:AT1G19050
Locus tag: AT1G19050
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F14D16.20; F14D16_20; response regulator 7
Summary: Encodes a member of the Arabidopsis response regulator (ARR) family, most closely related to ARR15. A two-component response regulator protein containing a phosphate accepting domain in the receiver domain but lacking a DNA binding domain in the output domain. Involved in response to cytokinin and meristem stem cell maintenance. Arr7 protein is stabilized by cytokinin.

What's a GeneRIF?

ARR7 is direct targets of ABI4.ARR7 negatively regulate abscisic acid-mediated inhibition of germination.
Title: ABI4 represses the expression of type-A ARRs to inhibit seed germination in Arabidopsis.
activity of cytokinin and auxin directly converges on the promoters of two A-type ARABIDOPSIS RESPONSE REGULATOR (ARR) genes, ARR7 and ARR15, which are negative regulators of cytokinin signalling and have important meristematic functions
Title: Hormonal control of the shoot stem-cell niche.
Phosphorylation of ARR7 is necessary for ARR7-mediated cytokinin response.
Title: Phosphorylation of Arabidopsis response regulator 7 (ARR7) at the putative phospho-accepting site is required for ARR7 to act as a negative regulator of cytokinin signaling.
ARR7 mainly acts as a transcriptional repressor for a variety of early cytokinin-regulated genes encoding transcription factors, signal transmitters, plant development, and cellular metabolism.
Title: Genome-wide expression profiling of ARABIDOPSIS RESPONSE REGULATOR 7(ARR7) overexpression in cytokinin response.
