Mustard plants' response to light duration could revolutionize agriculture.
The researchers measured how phytochrome in mustard seedlings responds to far red light. They found that the amount of active phytochrome changes depending on how long the seedlings were kept in the dark before being exposed to far red light. The longer the seedlings were in the dark, the less active phytochrome there was. This suggests that it's difficult to keep phytochrome levels constant in mustard seedlings over time.
