The integrated Plant-Atmosphere-Soil System (iPASS)

The integrated Plant-Atmosphere-Soil System, or iPASS, Initiative is bold innovative research for understanding, predicting and controlling the plant ecosystem as an interacting unit of plants, microbes, soil and surrounding atmosphere (the plant ecosystem interactome).

Key goal: Define first-principles that govern flow and transformations of carbon, nitrogen, and water through the integrated plant-atmosphere-soil system.

Key deliverable: A virtual Plant-Atmosphere-Soil System (vPASS), a computational model describing how genomic and environmental variables inform traits and responses at different scales, from molecules to plant to plant ecosystem.

Information in the plant genome propagates through plant-microbiome-soil-atmosphere interactions to inform emergent traits and responses at the ecosystem level.
