Abstract
The history of research on gravitropism has been largely confined to the primary root-shoot axis and to understanding how the typically vertical orientation observed there is maintained. Many lateral organs are gravitropic too and are often held at specific non-vertical angles relative to gravity. These so-called gravitropic setpoint angles (GSAs) are intriguing because their maintenance requires that root and shoot lateral organs are able to effect tropic growth both with and against the gravity vector. This chapter describes methods and considerations relevant to the investigation of mechanisms underlying GSA control.
