A 3 year postdoc position is available in the plant-soil interactions lab. Use imaging, metabolomics, isotope labeling, metagenomics to uncover how plants alter the biophysical processes in the rhizosphere. For details and to apply
Project led by Balwant Singh, Feike Dijkstra and Charles Warren has been funded by soil science challenge. The project will investigate the role of plants in organic matter stabilization.
We are delighted to share our proposal entitled “The critical role of rhizosheath biophysics in plant water availability” has been funded by the Australian Research Council. Chief Investigators are Charles Warren, Iain Young, Richard Trethowan and Sheikh Rabbi (all from University of Sydney) Project summary This project aims to determine how plants can increase their …
Paper published today in Soil Biology & Biochemistry describing estimation of metabolite synthesis from D2O labelling and mass spectrometry. Soil respiration was unaffected by up to 87 atom% D2O. D2O addition led to quantifiable 2H enrichment of metabolites. Turnover of pools due to synthesis differed among metabolites from ten days to multiple years.
Paper published today in Rhizosphere by Sheikh Rabbi and University of Sydney colleagues examining how rhizosheath of wheat roots affects water use.
Stefano Manzoni (Stockholm University) led an innovative modelling study exploring implications of intracellular storage for soil processes. The paper has been published today in Front. Ecol. Evol
Collaborator David Israel (University of Helsinki) led a study examining roles of different plasma membrane aquaporins (PIPs) in leaf-level gas exchange of Arabidopsis thaliana. It has just been published in Journal of Experimental Botany
Congratulations to Grace Liang and Shota Matsumura for completing their honours projects. Grace investigating the role of membrane lipids in the economics of phosphorus in plants and soil microbes. Shota examined whether plants can avoid competing for N by specialising in uptake of N in different chemical forms. Both Grace and Shota worked incredibly hard and …
We’ve just had a paper published in Soil Research showing inconsistent trends in intact lipid composition with altitude. Rather than temperature (altitude) related trends in lipids we found that low pH led to accumulation of some lipids — perhaps due to slowed hydrolysis and/or microbial utilization.
Our manuscript on osmolyte fluxes in soil was recently voted 2021 Editors’ Choice in Soil Biology and Biochemistry based on the new insights provided to the long-standing question of whether osmolytes fuel the pulse of respiration when dry soil is re-wet. Read the editorial.
