Genetically manipulating plants can reduce their water needs
Now researchers have found that this can be achieved by genetically altering plants' stomata, the tiny openings on the leaf surface through which carbon dioxide is absorbed and water evaporates.
"We now have genetic tools to pre-adapt crops to future, drier climates. The goal here is to maintain or improve productivity with less water," said Dr. Peter Franks, lead author of the New Phytologist study.
