WebAbstract Polyploidy is widely acknowledged as a major mechanism of adaptation and speciation in plants. The stages in polyploid evolution include frequent fertility … WebStructural colour reflected by photonic materials is typically attributed to highly ordered nanostructures with periodicities on the 100-nm length scale. When investigating structural colour in animals and plants, it is however becoming increasingly evident that brilliant photonic colour can also arise from seemingly disordered morphologies.

WebPolyploidy is generally more prevalent in long-lived perennial plants. It also tends to increase with higher latitudes and elevations. It is theorized that plants with access to more genetic information are better able to adapt to colder growing conditions.
