Plant-mediated diffusion of greenhouse gases from flooded soils to the atmosphere. Rice develop aerenchyma spaces in roots, internodes, and leaf blades, forming a low-resistance pathway (continuum of gas spaces), that facilitates the bidirectional diffusion of O2 from the atmosphere down to the flooded soil, and CH4, CO2 and/or N2O in the opposite direction, from the rhizosphere to the atmosphere. Asterisk keys in cross-sections from roots, internodes, and leaf blade tissues, indicate aerenchyma spaces. Created with BioRender.com.
