MAX2 RNI-like superfamily protein [Arabidopsis thaliana (thale cress)] - Gene

Summary

Go to the top of the page Help

Official Symbol: MAX2
Official Full Name: RNI-like superfamily protein
Primary source: TAIR:AT2G42620
Locus tag: AT2G42620
See related: Araport:AT2G42620
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: AtMAX2; F14N22.11; F14N22_11; MORE AXILLARY BRANCHES 2; ORE9; ORESARA 9; PLEIOTROPIC PHOTOSIGNALING; PPS
Summary: The mutations at MAX2 cause increased hypocotyl and petiole elongation in light-grown seedlings. Positional cloning identifies MAX2 as a member of the F-box leucine-rich repeat family of proteins. MAX2 is identical to ORE9, a proposed regulator of leaf senescence. Involved in positive regulation of light responses.

This study provides genetic evidence that the functions of the MAX2 orthologs, and perhaps the MAX2 signaling pathways, are conserved in parasitic and non-parasitic plants. OaMAX2 of Orobanche aegyptiaca and Arabidopsis AtMAX2 share conserved functions in both development and drought responses.
