The shape of produce is an important agronomic trait. The knowledge of the cellular regulation of organ shapes can be implemented in the improvement of a variety of crops. The plant-specific Ovate Family Proteins (OFPs) regulate organ shape in Arabidopsis and many crops including rice, tomato, and melon. Although OFPs were previously described as transcriptional repressors, recent data support a role for the family in organ shape regulation through control of subcellular localization of protein complexes. OFPs interact with TONNEAU1 RECRUITMENT MOTIF (TRMs) and together they regulate cell division patterns in tomato fruit development. OFPs also respond to changes in plant hormones and responses to stress. The OFP-TRM interaction may work in conjunction with additional shape regulators such as IQ67 Domain (IQD) proteins to modulate the response to tissue level cues as well as external stimuli and stressors to form reproducible organ shapes by regulating cytoskeleton activities.
