SHI RELATED SEQUENCE(SRS), which encode proteins with a single zinc finger motif. The genes are members of a small gene family of putative transcription factors in which the SHORT INTERNODES (SHI) gene is found. The predicted amino acid sequence of SHI has acidic and glutamine-rich stretches and shows sequence similarity over a putative zinc finger region to three presumptive Arabidopsis proteins. This suggests that SHI may act as a negative regulator of GA responses through transcriptional control. We identified 14 SRS genes, including JTY(5), LWM(4) and F106(5).
