The Don’t Let Your Houseplants Hit the Snooze edition

Plants use an “internal alarm” to alert them to spring. “While digging through the DNA of a small cabbage-like plant called Arabidopsis, [Sibum] Sung and a colleague discovered that the production of a special molecule could be turned on or off by a string of genetic material. When the plant gets cozy for the winter, this molecule is not produced, repressing a plant’s ability to create flowers. But after 20 days of consistently frigid weather, production of the molecule gets turned back on, signaling another gene to stop repressing flower production and start preparing for spring. The plant takes another 10-20 days to prime itself for warmer temperatures. Without the 20 days of freezing temperatures, the molecule wouldn’t be produced — even if there is a brief spike in the thermometer reading.” (via Physorg.com)
