A once-silent wheat gene may hold the secret to growing far more grain from every field. Credit: Shutterstock ====================================================================== Scientists at the University of Maryland have uncovered the genetic key behind a rare wheat variety that produces three grains where ordinary wheat grows just one. The team found that a normally inactive gene, WUSCHEL-D1, becomes active early in flower development, causing the plant to form extra ovaries that can each grow into a grain. This discovery could allow breeders to develop new, higher-yielding wheat varieties without needing more land or resources, offering a major step toward meeting global food demands...
