New discoveries about the way that plants breathe could allow scientists to genetically engineer more water-efficient plants. Researchers found that plants lose large quantities of water when they open their pores to admit carbon dioxide, so by boosting plants' carbon dioxide receptors it's possible to make them less thirsty. "What we see is that plants can grow, but they need less water," said the study's lead author.
