Photosynthesis in extreme temperatures: from single proteins to whole organisms
Photosynthetic organisms, known as phototrophs, play a crucial role in sustaining life by providing food and oxygen. However, temperature changes can impose significant stress on their light-harvesting process, necessitating successful adaptation for survival. Failure to adapt to temperature changes can lead to ecological disasters.
Volha Chukhutsina investigates photoregulation in response to temperature changes, spanning from individual proteins to entire organisms. By unraveling the mysteries of temperature-dependent photoregulation, we can gain insights into the resilience and adaptability of photosynthetic organisms in a changing climate.
