Analyses of a Swedish tree-ring archive suggest that increased atmospheric carbon dioxide has lowered soil-nitrogen supply, which could cap carbon storage by land ecosystems.

Nitrogen isotope tree-ring chronologies show that rising atmospheric CO2 has reduced nitrogen availability in boreal forests in Sweden, suggesting that elevated atmospheric CO2 is causing oligotrophication in boreal forests.

ISME supports MSc/PhD graduate students and postdocs to develop academically via the Scholar Mobility Fund. Please submit your application by 1 October to study at a host institution abroad.

Aspen trees follow a precise annual rhythm, shaped by the changing seasons. Researchers at UPSC have mapped this natural calendar at the genetic level, comparing trees grown outdoors and in the lab. T...

Plant roots live in constant contact with diverse microbes in the soil. Plant fitness, therefore, relies on signaling pathways that mount an effective immune response against pathogens while fosterin...

<p> We have an open, fully funded PhD position on the causes and epidemiology of truffle rot in Australian orchards. The PhD student will be enrolled at the University of Melbourne under the supervision of Niloofar Vaghefi and Camille Truong from the Royal Botanic Gardens Victoria. </p> <p> The project will elucidate the biotic and abiotic causes of truffle rot across different regions and provide recommendations for improved management, while equipping the industry with diagnostic tools for early and reliable detection in soils. Activities include identifying affected farms and potential experimental sites in collaboration with growers, surveys of fungi, bacteria and oomycetes associated with truffle rot, and assessing the pathogenicity of commonly isolated microorganisms using glasshouse and field trials. </p> <p> <strong>Eligibility criteria:</strong> </p> <ul> <li>Hsc or Msc in biological sciences or a relevant field, experience in conducting both fieldwork and molecular biology work. </li> <li>Demonstrated writing and communication skills in English, including with stakeholders. </li> <li>Background and laboratory skills in mycology or plant pathology, as well as bioinformatics skills, are desirable. </li> <li>The successful candidate will be based in the Parkville campus in Melbourne and will require to travel for field experiments. </li> </ul>

Background The rhizosphere is a critical microenvironment that plays key roles in plant nutrient availability, largely due to root interactions with rhizospheric microbes. However, we lack suitable me...
