Phylogenetic relationships of circadian clock related proteins. Neighbor-joining phylogenetic trees were built from the protein alignments of the indicated sequences. a) PRR gene family, b) CCA1/LHY gene family, c) GI genes. Accession numbers are given in Table 1. Bootstrap values were calculated from 10,000 permutations.
