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

New papers published – Glandular trichomes and stomatal conductance play crucial roles in protecting plants against ozone stress

Text by Shuai Li Two papers studying how plants cope with ozone stress were recently published in the journal Plant Cell & Environment. The first paper estimates the possible protective role of non-glandular and glandular trichomes on the leaf surface … Continue reading

New paper published – Oak gall wasp infections of Quercus robur leaves lead to profound modifications in foliage photosynthetic and volatile emission characteristics

Text by Linda-Liisa Veromann-Jürgenson Everyone with keen eyes that has been walking in wooded areas in the recent years must have noticed small growths on tree leaves called galls. Sometimes the infections can be massive, where it is hard to … 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 published – Toxic Influence of Key Organic Soil Pollutants on the Total Flavonoid Content in Wheat Leaves

Text by Lauri Laanisto Another study through Ülo Niinemets´connection in Romania (see the one about the effects of wifi and phone waves on volatiles here). This time they looked into how textile dyes and antibiotics (which are the main classes … Continue reading

New paper published – Regulation of Floral Terpenoid Emission and Biosynthesis in Sweet Basil (Ocimum basilicum)

Text by Lauri Laanisto It´s a pretty chemical paper about the volatiles emitted by different organs of basil. This study was led by Chinese postdoc Yifan Jiang, who together with Jiayan, Shuai and Ülo (all from Ülo Niinemets´ workgroup) studied … Continue reading
