Effect of plant in atmosphere methane cycle

Methane is one of the main green house gases which can make the climate warming. The terrestrial plants have the ability in releasing the methane in the recent years, these researches are the challenge to the present theories which the terrestrial plants are the channel connecting the soil and atmosphere in releasing methane. This mechanism of theory is unknown and questioned. The effect of terrestrial plant on the methane cycle in the atmosphere, including comparison in different theories, the contribution in methane cycle in atmosphere by terrestrial plant in the future was discussed in order to provide the theories to evaluate the effect and the potential of terrestrial plant in the methane cycle.
