🌾🧬 ROAD1, a rice-specific orphan gene, confers drought tolerance without yield loss. It bypasses ABA receptors by binding OsPP2C68, locking SnRK2 in active form. Field trials show up to 35% higher yield under drought.
Works across maize, wheat, and more. #plantscience www.cell.com/cell/fulltex...

An Oryza orphan gene confers trans-species drought tolerance
ROAD1 is an Oryza-specific orphan gene that co-opts conserved ABA signaling to enhance
drought tolerance without obvious growth defects or yield penalty under normal conditions.
