Seeing Is Believing: Advances in Understanding of Root–Rhizosphere Dynamics Posters

Session ID#: 50025

Session Description:
In recent years, compilation of a global fine-root ecology trait database (FRED) highlighted gaps in our understanding of belowground plant traits that limits our ability to project plant responses to changing environmental conditions (Iversen et al. 2017 doi:10.1111/nph.14486). ‘Root functional traits’ are key to understanding root dynamics, but only 3% of root trait observations are related to function. Even less is known about root-rhizosphere dynamics, which operate in a unique environment with myriad microbes, altered soil structure, moisture, hydraulic conductivity and nutrient availability. Advances in our understanding of root-rhizosphere dynamics will improve management systems and help refine model predictions of future ecosystem function. We invite presentations on new ways to conceptualize and observe root traits, root physiology and the interaction of roots with the surrounding rhizosphere. Field, laboratory, advanced imaging, meta-analysis, modeling and cross-disciplinary studies across scales are highly encouraged.
