摘要： Seed germination is an important event in the life cycle of seed plants, and is controlled by complex and coordinated genetic networks. Many genes involved in the regulation of this process have been identified in different plant species so far. Recent studies in both Arabidopsis and wheat have uncovered a new role of MOTHER OF FT AND TFL1 (MFT) in seed germination. Here, we reported a homolog of MFT in soybean (GmMFT) which strongly expressed in seeds. Detailed expression analysis showed that the mRNA level of GmMFT increased with seed development but declined during seed germination. The transcription of GmMFT also responded to exogenous application of ABA and GA3. Ectopic expression of GmMFT CDS in Arabidopsis moderately inhibited seed germination. All these evidences suggest that GmMFT may be a negative regulator of seed germination.
