Gene expression levels of Aquilegia flowering time homologs over the course of development. A. AqFT expression levels over the course of pre-vernalization development followed by during vernalization and post-vernalization time points, +/- the standard error. B. All FPI homologs were assayed for relative expression at three time points: seedlings, pre-vernalization (pre-vern) 12 to 15 leaf plants, and seven-day post-vernalization (post-vern) plants. Plant apices and young leaves were collected for RNA isolation 7.5 h after dawn in LD. Relative mean expression of genes from six plants at each developmental time point, +/- the standard error. Fold change between the seedling and the pre-vernalization and the pre-vernalization and the post-vernalization values is presented for each gene.
