Significance Daily rhythms of gene expression ensure that biological processes occur at the optimal time day. In plants, temporally regulated include traits ecological and agricultural importance, understanding how changes in daily modify such has broad implications. We find natural genetic variation can accurately temporal waveforms during day by influencing light signaling pathways, rather than circadian rhythms. further show transcriptional patterns induced alleles are sufficient to affect downstream molecular outputs cause phenotypic diversity. Such could provide an advantage adjusting activity while avoiding pleiotropic effects associated with severe disruptions system.
