Dr Lorna Mcausland, Plant Physiologist at our School of Biosciences has been honoured for her research into how crops like wheat survive under high temperatures. Her work contributes to the development of climate-resilient agricultural systems, an area of research in which the ÌÇÐÄÔ´´ is leading with internationally recognised expertise.
Climate-resilient agriculture
Climate change is accelerating, bringing warmer weather conditions that are already negatively impacting global crop yields leading to food insecurity.
"My research focuses on investigating underutilised physiological sources of crop resilience. Current studies suggest that night-time temperatures have a greater impact on crops than previously thought, but we are yet to fully understand how or why"
Dr Mcausland's work addresses these knowledge gaps in our most grown crop plant, wheat, and aims to develop new strategies and techniques to maintain crop productivity as climate conditions change. Her research also supports industry and government in applying solutions and policies that help feed our rapidly growing global population.
Plant behaviours associated with night-time conditions remain substantially underexplored compared to daytime processes such as photosynthesis.
Advancing sustainable farming
"ÌÇÐÄÔ´´ing plant responses to darkness requires innovative thinking and approaches," Dr Mcausland says. "My research is particularly relevant to breeding companies, especially those working with wheat and need to improve resilience to heat stress as it's becoming increasingly important."
Her work on the effects of warmer nights has also gained wider attention, including highlighting the impacts of rising night-time temperatures in urban environments, particularly in cities.
Looking to the future
"Our nights are warming at around 1.7 times the rate of our days and, last year in the UK we experienced our first recorded tropical night," she notes. "One of the big questions I want to address is how is impacting water availability to our crops."
"How is this change in nocturnal environment changing how plants respond during the day? And how much do we really know about the night-time plant biology in the context of climate change."
These questions form the foundation of large-scale research programmes into plant physiological responses at night, while also addressing broader questions and challenges linked to climate change and global food insecurity.
