SPINDLY is a nuclear-localized repressor of gibberellin signal transduction expressed throughout the plant.

Plant physiology - 1 Jun 2002

Abstract excerpt

SPY (SPINDLY) encodes a putative O-linked N-acetyl-glucosamine transferase that is genetically defined as a negatively acting component of the gibberellin (GA) signal transduction pathway. Analysis of Arabidopsis plants containing a SPY::GUS reporter gene reveals that SPY is expressed throughout the life of the plant and in most plant organs examined. In addition to being expressed in all organs where phenotypes...
