Previously, we described the AtGRF [Arabidopsis thaliana growth-regulating factor (GRF)] gene family, which encodes putative transcription factors that play a regulatory role in growth and development of leaves and cotyledons. We demonstrate here that the C-terminal region of GRF proteins has transactivation activity. In search of partner proteins for GRF1, we identified another gene family, GRF-interacting factor (GIF), which comprises three members.

- OsGRF1 is a rice gene that encodes a novel transcriptional regulator, identified alongside eleven homologs in the rice genome.
- All OsGRF proteins share two conserved domains and are primarily expressed in young, growing tissues, with gibberellic acid increasing the expression of seven of these genes.
- High levels of OsGRF1 transcripts are found in the shoot apical meristem, suggesting its role as a transcriptional activator involved in regulating vegetative growth in rice.
Previously, we identified a novel rice gene, GROWTH-REGULATING FACTOR1 (OsGRF1), which encodes a putative transcription factor that appears to play a regulatory role in stem elongation. We now describe the GRF gene family of Arabidopsis thaliana (AtGRF), which comprises nine members. The deduced AtGRF proteins contain the same characteristic regions--the QLQ (Gln, Leu, Gln) and WRC (Trp, Arg, Cys) domains--as do OsGRF1 and related proteins in rice, as well as features indicating a function in transcriptional regulation.
