Genes in the photoperiodic pathway are differentially regulated in lwd1lwd2 plants. Transcriptomic comparison was performed to analyze whether genes in the four pathways regulating flowering time are differentially regulated in 31-d-old wild-type and lwd1lwd2 plants. Expression changes between wild-type and lwd1lwd2 plants were color coded with extreme red (for 5-fold up-regulated) and extreme green (for 5-fold down-regulated) in lwd1lwd2. The fold change of gene expression in the lwd1lwd2 double mutant is indicated. CO and FT were not included in this list because they were classified as “absent” in at least one of the four ATH1 hybridization experiments (see “Materials and Methods”). Expression data shown are listed in Supplemental Table S1.
