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.

Opposite metabolic responses of shoots and roots to drought

scireports Opposite metabolic responses of shoots and roots to drought by Albert Gargallo-Garriga, Jordi Sardans, Míriam Pérez-Trujillo, Albert Rivas-Ubach, Michal Oravec, Teodor Parella and Josep Peñuelas. Scientific reports 4, Article number: 6829, October 2014. DOI: 10.1038/srep06829

Shoots and roots are autotrophic and heterotrophic organs of plants with different physiological functions. Do they have different metabolomes? Do their metabolisms respond differently to environmental changes such as drought? We used metabolomics and elemental analyses to answer these questions.

Drought enhances folivory by shifting foliar metabolomes in Quercus ilex trees

“Drought enhances folivory by shifting foliar metabolomes in Quercus ilex trees”

Albert Rivas-Ubach, Albert Gargallo-Garriga, Jordi Sardans, Michal Oravec, Laia Mateu Castell, Míriam Pérez-Trujillo,Teodor Parella, Romà Ogaya, Otmar Urban and Josep Peñuelas. January 2014. New Phytologist DOI: 10.1111/nph.12687

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
