The plant clock
Previous analyses of the circadian clock in the plant Arabidopsis thaliana have turned up just a few genes regulated by the clock. In the 15 December Science, Harmer et al. use oligonucleotide-based arrays to find a vast new collection of clock-regulated genes (Science 2000, 290:2110-2113). Using probes derived from tissue harvested every four hours, and an array representing 8,200 different genes, Harmer et al. find that 453 genes (6%) fit a cosine test wave with a period between 20 and 28 hour
