Abstract

In higher plants, shoots show a negative gravitropic response. To elucidate the molecular mechanisms of this phenomenon, mutational analyses usingArabidopsis 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 novelshootgravitropic (sgr) mutants inArabidopsis thaliana that have dramatic defects in shoot gravitropism.
