Water ‘thermostat’ could help engineer drought-resistant crops. Duke Today, August 27, 2014. Researchers have identified a gene that could help engineer drought-resistant crops. The gene, called OSCA1, encodes a protein in the cell membrane of plants that senses changes in water availability and adjusts the plant’s water conservation machinery accordingly. The findings, which appear in the journal Nature, could make it easier to feed the world’s growing population in the face of climate change. Picked up by MIT Technology Review.
