Methane (CH4) is one of the most abundant greenhouse gases in the atmosphere (Hartmann et al. 2013).
Boreal forests are generally considered as a net sink for atmospheric CH4 due to the methanotrophic
bacteria living in aerated soil layer (Topp and Pattey 1997; Kirschke et al. 2013). Plant species, such as
sedges and rice, are capable of transporting microbially produced CH4 from anaerobic soil conditions to
the atmosphere (Nouchi et al. 1990; Greenup et al. 2000). Recent studies have revealed that alongside with
above mentioned plants also trees are able to transport CH4 from anaerobic conditions to the atmosphere
(Terazawa et al. 2007; Rice et al. 2010; Gauci et al. 2010; Pangala et al. 2015; Machacova et al. 2016).
This transport is hypothesized to happen actively in transpiration stream (Pangala et al. 2015; Machacova
et al. 2016) or passively via aerenchymatic tissues (Terazawa et al. 2015). Furthermore, trees are noted to
be possible independent sources of CH4 from their leaves (Keppler et al. 2006) and stems in aerobic
conditions (Covey et al. 2012; Wang et al. 2016).
