Gibberellins are a group of plant hormones that affect growth. The effects of these hormones were first observed in the 1920s in rice plants that were attacked by a fungus, these rice plants grew unusually tall. Scientists isolated the substance responsible for the growth ( Gibberala fujikuroi ...
Aged herring sperm DNA can promote cell division. The molecule that is responsible for this was named kinetin. Soon after, a substance that had the same biological effect as kinetin was found in plants, it stimulated plant cells to divide when in culture with auxin. The substance was named c...
