New paper out – Diterpenoid fingerprints in pine foliage across an environmental and chemotypic matrix: Isoabienol content is a key trait differentiating chemotypes

Text by Lauri Laanisto Intraspecific variability in functional traits has emerged in recent years as a quite important phenomenon. At least in plant ecology. Traditional view in life sciences has promoted between-species differences as much more significant drivers of ecological … Continue reading

A case of plagiarism

Text by Ülo Niinemets <A letter to the editors of BMC Plant Biology> It has caught our attention that the paper of: Shi, J., Ma, C., Qi, D., Lv, H., Yang, T., Peng, Q., … & Lin, Z. (2015). Transcriptional … Continue reading

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 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 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 – Herbivory by an outbreaking moth increases emissions of biogenic volatiles and leads to enhanced secondary organic aerosol formation capacity

Text from EMU news Our researchers involved in a study demonstrating that enhanced insect herbivory under global change can alter climate Future warmer climates in northern latitudes facilitate dispersal of many insect herbivores and lead to overall greater plant herbivore … Continue reading

New paper published – Mono-and sesquiterpene release from tomato (Solanum lycopersicum) leaves upon mild and severe heat stress and through recovery: From gene expression to emission responses

Text by Leila Pazouki This study is the extension of our previous paper that was published by Lucian Copolovici in 2012. We made it broader and added gene expression analysis of some important terpene synthases such as β-phellandrene synthase and … Continue reading
