“…As reported in previous studies (Peng et al 2008;Lu et al 2015), our study showed that straw addition increased CH 4 production. The addition of nitrate with straw reduced CH 4 production compared with the treatment with straw alone.…”

“…Low H 2 concentrations were favored Methanocellaceae (Lu and Conrad 2005;Peng et al 2008). Previous studies found that Methanocellaceae predominated methanogenic activity at high temperatures (e.g., 45°C) (Peng et al 2008;Lu et al 2015). Methanocellaceae increased at 30°C in our study, indicating that they can also play an important role in CH 4 production at moderate temperatures.…”

“…mcrA gene is a functional marker gene encoding the MCR. This gene is highly conserved in all methanogens (Lehmacher and Klenk 1994;Springer et al 1995), which renders it suitable for application in molecular ecology studies, and has been widely used for investigation of methanogenic communities in rice paddy soils Lu et al 2015).…”

“…However, incorporation of straw also increases CH 4 production and emissions (Denier Van Der Gon and Neue 1995;Zou et al 2005). Several incubation studies have shown a highly dynamic structure of methanogenic archaeal communities during straw decomposition, with members responding differently to organic residue type, incubation temperature, and duration of incubation (Conrad and Klose 2006;Peng et al 2008;Conrad et al 2012;Lu et al 2015). It is thought that the concentrations of acetate and H 2 are the key factors that control methanogenic community composition during the degradation of rice straw (Conrad 2007).…”

Nitrogen fertilization and returning straw to paddy soil are important factors that regulate CH 4 production. To evaluate the effect of rice straw and/or nitrate amendment on methanogens, a paddy soil was anaerobically incubated for 40 days. The results indicated that while straw addition increased CH 4 production and the abundances of mcrA genes and their transcripts, nitrate amendment showed inhibitory effects on them. The terminal restriction fragment length polymorphism (T-RFLP) analysis based on mcrA gene revealed that straw addition obviously changed methanogenic community structure. Based on mcrA gene level, straw-alone addition stimulated Methanosarcinaceaes at the early stage of incubation (first 11 days), but nitrate showed inhibitory effect. The relative abundance of Methanobacteriaceae was also stimulated by straw addition during the first 11 days. Furthermore, Methanosaetaceae were enriched by nitrate-alone addition after 11 days, while Methanocellaceae were enriched by nitrate addition especially within the first 5 days. The transcriptional methanogenic community indicated more dynamic and complicated responses to straw and/or nitrate addition. Based on mcrA transcript level, nitrate addition alone resulted in the increase of Methanocellaceae and the shift from Methanosarcinaceae to Methanosaetaceae during the first 5 days of incubation. Straw treatments increased the relative abundance of Methanobacteriaceae after 11 days. These results demonstrate that nitrate addition influences methanogens which are transcriptionally and functionally active and can alleviate CH 4 production associated with straw amendment in paddy soil incubations, presumably through competition for common substrates between nitrate-utilizing organisms and methanogens.

“…Third, as hydrolysis of organic polymers may be the rate-limiting step in the methanogenic degradation of organic matter at higher temperature, increasing temperature could promote microbial activity, thus providing higher availability of C substrates for CH 4 production (Fey and Conrad 2003;Inglett et al 2012). In addition, shifts in the composition of archaeal community and methanogenic pathways toward hydrogenotrophic methanogenesis at high temperature may facilitate the consumption of CO 2 (Noll et al 2010;Lu et al 2015).…”

Temperature and moisture effects on organic carbon (C) decomposition (i.e., CO 2 and CH 4 emissions) determine the feedback of soil organic carbon (SOC) stocks in rice (Oryza sativa L.) paddies to climate change. In the present study, soils from a long-term (initiated in 1981) fertilization experiment [unfertilized control, combined inorganic nitrogen, phosphorus, and potassium fertilization (NPK), inorganic NPK plus organic manure (NPKM)] were incubated at 20 and 30°C under both aerobic and anaerobic conditions. Relative to aerobic conditions, anaerobic conditions significantly reduced CO 2 and total C release, but led to CH 4 production. On average, the temperature sensitivity (Q 10 ) of CH 4 production was 7.4 times greater than that of CO 2 production. Under anaerobic conditions, the contribution rates of CH 4 production to total C release significantly increased from an average of 2.4 % at 20°C to 14.5 % at 30°C, and to the global warming potential (GWP) from 18.1 to 59.9 %, respectively. Anaerobic conditions significantly reduced the Q 10 of CO 2 and total C release, but increased that of GWP. Manure-amended soils showed higher CO 2 and CH 4 production on a per gram soil C basis and lower Q 10 of CO 2 and total C production, but higher Q 10 of CH 4 production than those of the control and NPK soils. Therefore, our results suggest that there are significant interactive effects of temperature, moisture, and fertilization regimes on SOC decomposition in the paddy soil.
