A Plant’s Nutrient-Sensing Abilities can Modulate its Response to Environmental Stress

Understanding how plants respond to stressful environmental conditions is crucial to developing effective strategies for protecting important agricultural crops from a changing climate. New research led by Carnegie’s Zhiyong Wang, Shouling, Xu, and Yang Bi reveals an important process by which plants switch between amplified and dampened stress responses.

Understanding how plants respond to stressful environmental conditions is crucial to developing effective strategies for protecting important agricultural crops from a changing climate. New research led by Carnegie’s Zhiyong Wang, Shouling, Xu, and Yang Bi reveals an important process by which plants switch between amplified and dampened stress responses. Their work is published by Nature Communications.

To survive in a changing environment, plants must choose between different response strategies, which are based on both external environmental factors and internal nutritional and energy demands. For example, a plant might either delay or accelerate its lifecycle, depending on the availability of the stored sugars that make up its energy supply.

“We know plants are able to modulate their response to environmental stresses based on whether or not nutrients are available,” Wang explained. “But the molecular mechanisms by which they accomplish this fine tuning are poorly understood.”
