title: How do plant shoots bend up?  The initial step to elucidate the molecular mechanisms of shoot gravitropism using Arabidopsis thaliana.
abstract: In higher plants, shoots show a negative gravitropic response. To elucidate the molecular mechanisms of this phenomenon, mutational analyses using Arabidopsis thaliana are in progress. This minireview aims to present recent developments in the genetic analysis of shoot gravitropism in this organism. We focus mainly on our studies on the novel shoot gravitropic (sgr) mutants in Arabidopsis thaliana that have dramatic defects in shoot gravitropism.
