|a The trithorax group (TrxG) factors play a critical role in the regulation of gene transcription by modulating histone methylation. However, the biological functions of the TrxG components are poorly characterized in different plant species. In this work, we identified three allelic ethyl methane-sulfonate-induced mutants P7, R67 and M3 in the woodland strawberry Fragaria vesca. These mutants show an increased number of floral organs, a lower pollination rate, raised achenes on the surface of the receptacle and increased leaf complexity. The causative gene is FvH4_6g44900, which contains severe mutations leading to premature stop codons or alternative splicing in each mutant. This gene encodes a protein with high similarity to ULTRAPETALA1, a component of the TrxG complex, and is therefore named as FveULT1. Yeast-two-hybrid and split-luciferase assays revealed that FveULT1 can physically interact with the TrxG factor FveATX1 and the PcG repressive complex 2 (PRC2) accessory protein FveEMF1. Transcriptome analysis revealed that several MADS-box genes, FveLFY and FveUFO were significantly up-regulated in fveult1 flower buds. The leaf development genes FveKNOXs, FveLFYa and SIMPLE LEAF1 were strongly induced in fveult1 leaves, and their promoter regions showed increased H3K4me3 levels and decreased H3K27me3 levels in fveult1 compared to WT. Taken together, our results demonstrate that FveULT1 is important for flower, fruit and leaf development and highlight the potential regulatory functions of histone methylation in strawberry
