Description |
| UniProt | Transcription factor that binds to the DNA G-box motif 5'-CACGTG-3' of MAN7 promoter. Involved in the positive regulation of seed germination through MAN7 gene activation. MAN7 is required for both, loosening of the micropylar endosperm, and rupture of the seed coat in germinating seeds. {ECO:0000269|PubMed:23461773}. |
