Phylogenetic tree depicting SLEEPER genes from various species. Dark grey = CYTOSLEEPER cluster. Grey = DAYSLEEPER cluster. Light grey = Poaceae cluster. Sequences that were used for complementation studies have a black logo. * Contains 1 DAYSLEEPER gene (D), and CYTOSLEEPER (C). X These species contain one DAYSLEEPER ortholog (shown) and a CYTOSLEEPER ortholog (not depicted). The number inside the symbol is the number assigned to each gene. The tree is created from protein sequences aligned with ClustalW , processed by the RaxML algorythm, with bootstrap values enabled . Clusters have been given a color.
