Shifts in plant foliar and floral metabolomes in response to the suppression of the associated microbiota

logo_BMCPB“Shifts in plant foliar and floral metabolomes in response to the suppression of the associated microbiota” by A. Gargallo-Garriga, J. Sardans, M. Pérez-Trujillo, A. Guenther, J. Llusià, L. Rico, J. Terradas, G. Farré-Armengol, I. Filella, T. Parella and J. Peñuelas. BMC Plant Biology 2016; 16:78. DOI: 10.1186/s12870-016-0767-7

The significance of microbial populations to the health and physiology of human and animal hosts has become a burgeoning and increasingly newsworthy topic. Of course, plants are also hosts for microbial life, and our metabolomics new study in BMC Plant Biology suggests that microbial influence on plant biology is more complex than we currently appreciate.

Warming differentially influences the effects of drought on stoichiometry and metabolomics in shoots and roots

“Warming differentially influences the effects of drought on stoichiometry and metabolomics in shoots and roots” by Albert Gargallo-Garriga, Jordi Sardans, Míriam Pérez-Trujillo, Michal Oravec,Otmar Urban, Anke Jentsch, Juergen Kreyling, Carl Beierkuhnlein Teodor Parella and Josep Peñuelas. New Phytologist. March 2015. DOI: 10.1111/nph.13377

Plants in natural environments are increasingly being subjected to a combination of abiotic stresses, such as drought and warming, in many regions. The effects of each stress and the combination of stresses on the functioning of shoots and roots have been studied extensively, but little is known about the simultaneous metabolome responses of the different organs of the plant to different stresses acting at once. We studied the shift in metabolism and elemental composition of shoots and roots of two perennial grasses, Holcus lanatus and Alopecurus pratensis, in response to simultaneous drought and warming.

Diversity of pyrrolizidine alkaloids in native and invasive Senecio pterophorus (Asteraceae): Implications for toxicity

14Phytochemistry“Diversity of pyrrolizidine alkaloids in native and invasive Senecio pterophorus (Asteraceae): Implications for toxicity” by Eva Castells, Patrick P.J. Mulder  and Miriam Perez-Trujillo. Phytochemistry (2014) 108:137-146. DOI: 10.1016/j.phytochem.2014.09.006

Changes in plant chemical defenses after invasion could have consequences on the invaded ecosystems by modifying the interactions between plants and herbivores and facilitating invasion success. However, no comprehensive biogeographical studies have yet determined the phenotypic levels of plant chemical defenses, as consumed by local herbivores, covering large distributional areas of a species.

Plants respond to external environmental conditions such as drought or to the seasonal changes by shifting the foliar C:N:P:K stoichiometry and metabolome. Continue reading Drought enhances folivory by shifting foliar metabolomes in Quercus ilex trees

Metabolic responses of Quercus ilex seedlings to wounding analysed with nuclear magnetic resonance profiling

Plant Biology“Metabolomic responses of Quercus ilex seedlings to wounding simulating herbivory” By Jordi Sardans, Albert Gargallo-Garriga, Míriam Pérez-Trujillo, Teodor Parella, Roger Seco, Iolanda Filella, Josep  Peñuelas. Plant biology. April 2013. DOI: 10.1111/plb.12032.

Plants defense themselves against herbivory at several levels. One of these levels is the synthesis of inducible chemical defenses. By using NMR metabolomic technique we studied the metabolic changes of plant leaves after a wounding treatment simulating herbivore attack in the Mediterranean sclerophyllous tree Quercus ilex.

NMR-based Protocol for Ecometabolomics

13MEE“Ecometabolomics: Optimized NMR-based method” by Albert Rivas-Ubach, Miriam Pérez-Trujillo, Jordi Sardans, Albert Gargallo-Garriga, Teodor Parella, Josep Peñuelas. Methods in Ecology and Evolution, February 2013. DOI: 10.1111/2041-210X.12028

Metabolomics is allowing great advances in biological sciences and in particular Ecometabolomics (metabolomic approach for ecological studies). Ecometabolomics is a powerful tool that allows identifying changes in the metabolome of individuals of the same species associated to environmental changes, detecting and identifying biological markers.

Organic composition in soil studied by solid state NMR

Changes in soil bacterial community: diversity, composition and function triggered by drought-induced gap succession preceded changes in soil C stocks and quality ” Curiel-Yuste J., Barba J., Fernandez-Gonzalez A.J., Fernandez-Lopez M., Mattana S., Martinez-Vilalta J., Pau Nolis, Lloret F. Ecology and Evolution. Accepted 2012.

We investigated soil bacterial taxonomic composition, soil respiration and soil organic matter quantity and quality in a mixed Mediterranean forest where the Scots pine (Pinus sylvestris) population is affected by climatic drought-induced die-off, and replaced by Holm-oak (Quercus ilex) populations as the dominant tree species.

ECOMETABOLOMICS: Metabolomics in Ecological Studies

“Strong relationship between elemental stoichiometry and metabolome in plants” Albert Rivas-Ubach, Jordi Sardans, Miriam Pérez-Trujillo, Marc Estiarte and Josep Peñuelas.  PNAS, February 2012. DOI: 10.1073/pnas.1116092109

Shifts in the elemental stoichiometry of organisms in response to their ontogeny and to changing environmental conditions should be related to metabolomic changes because elements operate mostly as parts of molecular compounds. Here we show this relationship in leaves of Erica multiflora throughout their seasonal development and in response to moderate experimental field conditions of drought and warming.
