Table IV.

No. of blue-light-regulated known and predicted transcription factor genes categorized by family based on sequence similarity Genes with mRNA abundance either increased (induced) or decreased (repressed) above 1.8-fold are scored and classified into families. Genes induced or repressed within 1 h of blue-light irradiation were considered as early responded. All genes are counted only once, regardless of extra signature motif(s), thus this table is nonredundant.
