Function of Importin-βs in the Arabidopsis heat stress response
Rising temperatures due to climate change pose a serious threat to global crop production. Understanding the plant heat stress response is therefore critical to the fight against climate change. Heat stress is a major stressor of plants, disrupting nearly every part of normal plant function with effects ranging from reduced photosynthetic efficiency to premature cell death.
Importin-βs, a family of nuclear transport receptors that shuttle cargo between the nucleus and cytoplasm, are essential in many plant cellular processes, including stress response, immunity, and development. While some Arabidopsis importin-βs are known to be essential for thermotolerance, the mechanisms by which other importin-βs contribute to the plant heat response remain largely unexplored. In this project, my aim is to investigate changes in the localization of importin-β proteins within the plant cell during heat stress in the model plant Arabidopsis thaliana in order to gain insights into the mechanisms of the plant heat response.
