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 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

Musings – cultural VOCs and global isoprene patterns

Text by Lauri Laanisto Measuring volatile organic compounds (VOC), finding their pathways and translating the signals behind them is one of the main focus of our work group. Among the most common VOCs is isoprene, which, when emitted to atmosphere, … Continue reading
