Some plants kill own roots to survive chilly weather: Study
A Singapore-based study has found that some plants may selectively kill part of their roots to survive under cold weather conditions, similar to trees shedding their leaves to conserve energy. Scientists studying a mustard plant relative 'Arabidopsis' found at 4ÂºC, the roots' DNA starts getting damaged, following which some of the roots die preferentially, preventing the plant's death.
