Sweet duplication Some flowers have a specific hollow outgrowth wherein they store their nectar, a so called nectar spur. How these evolved is often a mystery. Now Colombian researchers show in the journal Annals of Botany that it might be the result of a gene duplication. Flowers of Tropaeolum longifolium can only be divided inContinue reading “Sweet duplication”

Orange flowers
Maybe orange will be possible For lots of flower breeders have one wish: breeding a flower with a unique colour. This allows their flower to stick out in a bunch of flowers. Despite their wish to be unique, some colours remain unattainable. Simply because the plant does not have the enzymes to make that specificContinue reading “Orange flowers”

Warm flowers We associate warm-bloodedness, or to be more precise the regulation of body temperature through burning nutrients, with animals. With mammals and birds, but not really with plants. There are however, also plants that regulate their temperature independent of their environment. Mostly they do this for a specific organ, for example, their flowers. OneContinue reading “Warm flowers”
Analog or digital
Analog or digital Often, I speak over gene on/off switches. About proteins that enable a gene to be read either more or less often. These gene on/off switches enable an analog regulation of their genes. In addition, a cell has a system to regulate a gene in a more digital manner, having a gene eitherContinue reading “Analog or digital”
