| Popis: | The onset of flowering, the change from vegetative to reproductive development, is a major life history transition in flowering plants. Recent work suggests that mutations in cis-regulatory mutations should play critical roles in the evolution of this (as well as other) important adaptive traits, but thus far there has been little evidence that directly links regulatory mutations to evolutionary change at the species level. While several genes have previously been shown to affect natural variation in flowering time in Arabidopsis thaliana, most either show protein-coding changes and/or are found at low frequency ( The transcription factor CONSTANS regulates the timing of flowering in Arabidopsis. Rosas et al. report that genetic variation in the cis-regulatory regions of this gene contributes to natural phenotypic variation in flowering time. |
