Growth and water use under constant or fluctuating light.

Growth and water use under constant or fluctuating light.

Faster #stomata evolved to increase photosynthetic capacity rather than water use efficiency

Integration of light quality signals regulates ABA abundance and stomatal movements during seedling establishment Obtaining sufficient light for photosynthesis and avoiding desiccation are two key challenges faced by seedlings during early establishment. Perception of light quality via specialised photoreceptor...

Really happy to see our paper about seedlings, stomata, and light signals is now online!

ERC grant helps to understand why the upper and lower surfaces of plant leaves differ Hanna HΓ΅rak, Associate Professor of Molecular Plant Physiology at the University of Tartu Institute of Technology, has received a prestigious European Research Council (ERC) grant to study how cell pa...

Thankful, happy and excited to be awarded an ERC consolidator grant to understand how and why some plants make stomata on their upper leaf surface. tuit.ut.ee/en/news/erc-... #ERCCoG @erc.europa.eu
