Genetics: Harnessing flower power in chrysanthemums Researchers have identified the genes that control the timing of flowering in chrysanthemums. For most plants, day-length indicates that it is time to flower. Greenhouse growers can produce out-of-season flowers by manipulating day length, but the process is expensive. Breeding varieties that respond more quickly could reduce costs, but requires a better understanding of the underlying genetics, especially in the subset of plants triggered by short days. Si-lan Dai and co-workers at Beijing Forestry University in China investigated which genes trigger flowering in Chrysanthemum lavandulifolium, a typical short-day plant. They found that flowering of chrysanthemum is controlled by a gene previously identified in long-day plants, and that amplifying the gene produced plants that flowered much sooner than ordinary plants. These findings may help in breeding varieties that are easily induced to bloom. |
