Researchers Find Proteins That Help Plants Survive Drought
In a study that promises to fill in the fine details of the plant world’s blueprint for surviving drought, a team of Wisconsin researchers has identified in living plants the set of proteins that help them withstand water stress.
The new study, published today (Aug. 23) in the Proceedings of the National Academy of Sciences, identifies the protein targets in cells of a key hormone that controls how plants respond to environmental stresses such as drought, excessive radiation and cold.
The work, which builds on decades of research with a key plant hormone known as abscisic acid, could help underpin the development of new crop plant strains capable of thriving in hotter, dryer climates. The work is considered important in light of the pressing need to expand and intensify agricultural production on marginal lands worldwide, and especially so in the context of global climate change.
