＜正＞EMBRYONIC FL0WER1（EMF1） together with EMF2 has very important role in the maintenance of vegetative development by repressing directly the flower organ identity genes in Arabidopsis. To investigate EMF1-mediated vegetative development, we have analyzed molecular function of EMF1-Interacting protein （EMF1IP） 1, 6, and 9 that had been isolated from yeast two-hybrid screen using EMF1 as bait, and are predicted to encode a MAP kinase （EMF1IP1）, zinc-finger protein （EMF1IP6） and a DnaJ-domain protein （EMF1IP9）, respectively. Using yeast two-hybrid system, it was revealed that middle region of EMF1 shows strong interaction only with the EMF1IP1, whereas C-terminal region of EMF1 shows the interaction with the EMF1IP6 and 9. We also found that C-terminal region of EMF1IP1 and N-terminal region of EMF1IP6 are involved in the interaction with EMF1, and entire EMF1IP9 is necessary for interaction with EMFl. Interestingly, the N-terminal region of EMF1IP6 includes B-box zinc-finger domain, indicating that the B-box zinc-finger might play an important role in the protein-protein interaction. As results of subcellular localization assay of EMF1IPs, it was suggested that EMF1IP1 is localized in nucleus, EMF1IP6 in both cytoplasm and nucleus, and EMF1IP9 in cytoplasm. In addition, experiments using EMF1IPs::GUS and semi-quantitative RT-PCR analysis revealed that EMF1 was expressed during most of vegetative developmental stages after germination, but not in floral clusters including inflorescence meristem. Especially EMF1 was strongly expressed during early growth stage of vegetative development. EMF1IPs were detected in all of developmental stages investigated except at 4 days after germination （DAG）, but differential expressions were observed during the developmental stages after 4 DAG These expression patterns suggest that the interaction between EMF1 and EMF1IPs might strongly occur during early growth stage. Taken together, our results suggest that the interaction between E
