Abstract: The paper reviewed the role of plants in the processes of methane production, oxidation and emission in soils. It was the abilities of different plants to excrete the quantity and quality of root exudates that resulted in discrepancies of methane production among plants and in plant growing seasons. The oxygen magnitude of the downward transport through the plant aerenechyma, which, in turn, also acted as a conduit for methane from the soil to the atmosphere, affected endogenous methane oxidation capacity with plants and with plant growing seasons. Plant through changing amount and density of plant aerenchyma altered its ability to transport methane from soil to atmosphere. In addition to soil properties, flux and pattern of methane emission from soils largely depended on plant abilities to excrete exudates and oxygen, and transport methane in different plant growing seasons.
