When heat spikes and water vanishes, plants cannot flee — they must rewire themselves at the molecular level, trading growth for survival. Researchers at the Boyce Thompson Institute have uncovered a hidden mechanism in this ancient bargain: a protein called DUS2 attaches chemical tags to RNA transcripts, signaling cells to dismantle photosynthesis machinery during stress and redirect energy toward endurance. Discovered through a rare integration of field observation and laboratory analysis across sorghum varieties in the Arizona desert, this finding illuminates not only how life persists unde
