Drought Tolerance in Plants Boosted by New Synthetic Chemical

Scientists have identified a chemical that helps plants better tolerate drought conditions, a discovery they say could help  boost crop production as extreme weather conditions become more common.

While scientists withheld water from each of these soybean plants for 14 days, the plant on the right was treated with the chemical quinabactin. According to scientists, the chemical causes pores, or stomata, to close firmly, preventing water loss, similar to the way a naturally occurring stress hormone known as abscisic acid does in drought-tolerant plants.
