Altered expression of SPINDLY affects gibberellin response and plant development.

Plant physiology - 1 Jul 2001

Swain S M, Tseng T S, Olszewski N E

Abstract excerpt

Gibberellins (GAs) are plant hormones with diverse roles in plant growth and development. SPINDLY (SPY) is one of several genes identified in Arabidopsis that are involved in GA response and it is thought to encode an O-GlcNAc transferase. Genetic analysis suggests that SPY negatively regulates GA response. To test the hypothesis that SPY acts specifically as a negatively acting component of GA signal...
