New paper published – Disproportionate photosynthetic decline and inverse relationship between constitutive and induced volatile emissions upon feeding of Quercus robur leaves by large larvae of gypsy moth (Lymantria dispar)

Text by Lauri Laanisto Another paper by Ülo´s former postdoc Lucian, who does a lot of small experiments, where they measure all sorts of factors that could affect organic volatile emissions in plants. This time the focus is on the … Continue reading

New member of our lab with new paper out – Stress Marker Signatures in Lesion Mimic Single and Double Mutants Identify a Crucial Leaf Age-Dependent Salicylic Acid Related Defense Signal

Text by Eve Kaurilind I joined to Prof. Ülo Niinemets group three months ago. Previously I studied stomatal function and structure in response to light and elevated CO2 during my master and PhD thesis at University of Tartu. I have … Continue reading

New paper published – Emissions of carotenoid cleavage products upon heat shock and mechanical wounding from a foliose lichen

Text by Lauri Laanisto I like that this paper starts with a metaphor: “Chlorophyll (Chl) is a double-edged sword for plants.” Because “This molecule is capable of harvesting sunlight, initiating the process of photosynthesis, but it also involves an unavoidable … Continue reading

New paper published – Functional traits of urban trees: air pollution mitigation potential

Text by Lauri Laanisto It probably happens quite rarely, but sometimes some of the most fundamental theoretical questions can be studied using applied research approach. Studying urban ecosystems is one of these rare occasions. In a blog post from last … Continue reading

New paper out – Herbivory by an Outbreaking Moth Increases Emissions of Biogenic Volatiles and Leads to Enhanced Secondary Organic Aerosol Formation Capacity

Text by Lauri Laanisto Couple of days ago I reported about a paper that studied how a rust fungus affects organic volatiles in a poplar (link to blog post). However, we have quite a few people in our lab studing … Continue reading

New paper out – Scaling of photosynthesis and constitutive and induced volatile emissions with severity of leaf infection by rust fungus (Melampsora larici-populina) in Populus balsamifera var. suaveolens

Text by Lauri Laanisto In addition to the role of abiotic stress in regulating the emissions of volatile organic compunds in plants, members of our lab also study biotic stress factors. For example leaf fungi. This is just one little … Continue reading
