Recessive-interfering mutations in the gibberellin signaling gene SLEEPY1 are rescued by overexpression of its homologue, SNEEZY.

Abstract

This article reports the genetic interaction of two F-box genes, SLEEPY1 (SLY1) and SNEEZY (SNE), in Arabidopsis thaliana gibberellin (GA) signaling. The SLY1 gene encodes an F-box subunit of a Skp1-cullin-F-box (SCF) E3 ubiquitin ligase complex that positively regulates GA signaling. The sly1-2 and sly1-10 mutants have recessive, GA-insensitive phenotypes… (More)
