Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT3G11540 SPY cytokinin upstream of the first exon Encodes a N-acetyl glucosamine transferase that may glycosylate other molecules involved in GA signaling. SPY may play a central role in the regulation of GA/cytokinin cross talk during plant development.
AT3G11540 SPINDLY gibberellin T-DNA insertion 13 bp upstream from ATG start. Encodes a N-acetyl glucosamine transferase that may glycosylate other molecules involved in GA signaling. SPY may play a central role in the regulation of GA/cytokinin cross talk during plant development.
