FRIEND OF LEAFY1 is necessary for gametophytic development in Arabidopsis thaliana.
Flower development is crucial for the survival of flowering plant species. Within the flower, development of the haploid gametophyte generation, the male pollen and the female embryo sac, is essential for reproduction. After meiosis, the resulting haploid spores divide mitotically to form multicellular structures. Within these structures, the gametes and accessory cells differentiate. FRIEND OF LEAFY1 (FOL1) is a C2H2 zinc finger transcription factor that is expressed in the inflorescence meristem, the flower meristem and in the developing male and female gametophytes. Loss of function mutations in the FOL1 locus cannot be recovered as homozygotes, suggesting this gene is required for gametophyte development and cannot be passed through the gametes. Preliminary data suggests that FOL1 is consistent with this hypothesis. We will present our analysis of the role of FOL1 in male and female gametophyte development, including results of complementation analysis, and its expression pattern in developing pollen and embryo sacs.
