Opposite regulation of gene expression by EMF1 and ULT1. A, Relative expression levels of flower MADS box genes in plants at 7 DAG (left panel) and 15 DAG (right panel) using data based on GeneChip analysis. The log₂ values of the fold change were calculated for comparison of the changes in gene expression levels in LFYasEMF1, ult1-3, and LFYasEMF1 ult1-3 plants relative to wild-type plants. A log₂ ratio of 1 is the same as a 2-fold change in gene expression. B, Relative expression changes of flowering-time genes. C, Relative expression changes of seed genes.
