Function
AGL15 is a transcription factor that negatively regulates flowering, likely through the photoperiodic pathway. It functions as both a transcriptional activator and repressor, binding DNA specifically to large CArG motifs (5'-CC(A/T)8GG-3'). AGL15 is involved in regulating early embryo development, preventing premature perianth senescence and abscission, and influencing fruit development and seed desiccation. It upregulates the expression of several genes, including *DTA4*, *LEC2*, *FUS3*, *ABI3*, *AT4G38680/CSP2*, and *GRP2B/CSP4*, and can enhance somatic embryogenesis *in vitro*.
