Genome tiling arrays uncover extensive circadian-regulated transcription across the Arabidopsis genome.

Key findings

Known clock genes cycle as expected; many additional exons/ncRNA features show circadian rhythms.

Methodology

Sampled a 2-day circadian time course at 4-hour resolution on whole-genome tiling arrays.

Limitations

Two-day series limits period precision versus longer time courses.
