    many plants are photomassed during the day and "fall asleep" at night when the light is low. Plants "falling asleep" depends on two enzymes as "switches," a new Japanese study says, a finding that promises to be used to design crops that adapt to different environments.
    plants are photo-cooperatively usthyured by serenity. Past studies have found that plants "wake up" when light becomes stronger during the day, the emerald increases activity, and then "sleeps" when the light darkens at night, and the leafy body weakens its activity, which makes photomatching more efficient overall and avoids wasting energy. Researchers have previously discovered mechanisms that allow plants to "wake up", but the mechanism by which plants "fall asleep" is unclear.
    a new issue of U.S.
    , researchers at Tokyo University of Technology in Japan report that two enzymes, called TrxL2 and 2CP, work together to "switch" plants to "sleep." Some proteins in plants are reduced when they "wake up", and these enzymes allow them to be oxidized again, allowing the plants to "sleep". The cycle of redox reactions also causes plants to circulate between "sleep" and "wake up".
    experiments with athropomorphic mustard showed that if the effects of these two enzymes were inhibited, the aphedic mustard could not "sleep" at night, and the leafy greens experienced inefficient photomembering in low light.
    researchers say the findings shed light on how plants prevent energy waste at night, bringing new breakthroughs to basic research in plant science and promising ways to design environmentally adaptable crops in the future. (Source: Xinhua News Agency, Huayi)
