Project description
In nature, timing of flowering has a major implications for successful progeny production in plants. In this project, heritable differences in flowering responses to environmental cues was examined using a model organism for evolutionary biology - the monkeyflower (Mimulus). Results show that annual monkeyflowers have a strict minimum daylength requirement for flowering. Monkeyflowers originating from environments where daylength at the beginning of growing season is longer have longer minimum daylength requirement than those originating from sites where growing season starts earlier. Interestingly, it was also found that circadian rhythms of these plants differed. Results show that the observed differences are due to genetic differences. Genetic analyses are used to identify what kind of genes have been targets of natural selection in evolution of flowering responses in different environments.
