Making plant methane formation visible-Insights from application of ¹³C-labeled dimethyl sulfoxide.

ABSTRACT: Methane (CH₄) formation by vegetation has been studied intensively over the last 15 years. However, reported CH₄ emissions vary by several orders of magnitude, thus making global estimates difficult. Moreover, the mechanism(s) for CH₄ formation by plants is (are) largely unknown.Here, we introduce a new approach for making CH₄ formation by plants clearly visible. By application of ¹³C-labeled dimethyl sulfoxide (DMSO) onto the leaves of tobacco plants (Nicotiana tabacum) and Chinese silver grass (Miscanthus sinensis) the effect of light and dark conditions on CH₄ formation of this pathway was examined by monitoring stable carbon isotope ratios of headspace CH₄ (δ¹³C-CH₄ values).
