Relative expression levels of flowering-related genes. 10-day-old seedlings were treated with or without 50 µM abscisic acid (ABA) for 3 hours. Gene expression in Col without ABA treatment were taken as the reference level; then fold-changes in abi5-7 (Col), ABI5-5, and ABI5 S42AS145AT201A plants were normalized relative to the reference. Data are mean ± standard errors of three independent experiments (n > 4 for each experiment).
