STM interacts with a floral integrator protein to maintain inflorescence meristem identity.
In plants, shoot development is characterized by the continuous production of organs initiated on the flanks of the shoot apical meristem (SAM). The activity of the SAM is differentially regulated during distinct developmental stages. The floral transition transforms the vegetative meristem into an inflorescence meristem, which marks the beginning of the reproductive phase. The homeodomain transcription factor, SHOOTMERISTEMLESS (STM), is essential for meristem maintenance. In addition, the characterization of the weak allele stm-10 that displays a late flowering phenotype with defects in floral specification during inflorescence development indicates the participation of STM in flowering. To gain further insights into the role of STM, a two-hybrid screen was performed in order to identify floral integrators that associate with this homeodomain protein. The results will be discussed.
