Atmospheric methane is the second most important greenhouse gas after carbon dioxide, and is responsible for about 20% of the global warming effect since pre-industrial times. Rice paddies are the largest anthropogenic methane source and produce 7–17% of atmospheric methane. Warm waterlogged soil and exuded nutrients from rice roots provide ideal conditions for methanogenesis in paddies with annual methane emissions of 25–100-million tonnes. This scenario will be exacerbated by an expansion in… Expand
Sustainability: Bypassing the methane cycle
TLDR
In a warming climate, 'high-starch low-methane' rice could offer a sustainable means for providing high-quality biomass while reducing the negative effect of rice agriculture on atmospheric greenhouse gas emissions. Expand
Comprehensive analysis of SUSIBA2 rice: The low-methane trait and associated changes in soil carbon and microbial communities.
TLDR
SUSIBA2 rice substantially reduces CH4 emissions and that SUSI BA2 can potentially mitigate theCH4 emissions of japonica and indica rice under distinct cultivation conditions are shown. Expand
Comparative Analysis of Root Microbiomes of Rice Cultivars with High and Low Methane Emissions Reveals Differences in Abundance of Methanogenic Archaea and Putative Upstream Fermenters
TLDR
The root microbiome of the high-emitting cultivar is enriched both in methanogens and in taxa associated with fermentation, iron, and sulfate reduction and acetogenesis, processes that support methanogenesis. Expand
Effects of heterogous expression of Hvsusiba2 rice on methane mitigation and related micro-organism abundance in paddy fields
A field experiment was conducted to explore the effects of genetically modified rice with Hvsusiba2 gene on paddy field methane mitigation. Hvsusiba2 gene is a transcription factor that acts on theExpand
OsRGA1 optimizes photosynthate allocation for roots to reduce methane emissions and improve yield in paddy ecosystems
Abstract Rice cultivars influence methane emissions from paddies; however, which plant traits account for this effect and the corresponding mechanisms are poorly understood. A meta-analysis of dataExpand
Limited potential of harvest index improvement to reduce methane emissions from rice paddies
TLDR
The potential of CH4 mitigation from rice paddies through HI improvement is in fact small and it is estimated that future plant breeding efforts aimed at HI improvement to the theoretical maximum value will reduce CH4 emissions in CF systems by 4.4%. Expand
Crop Improvement strategies for Mitigation of Methane Emissions from Rice
Climate change and its effects on agriculture will impact global food security. Rice (Oryza sativa L.), the major staple crop of the world, is subjected to substantial environmental constraints andExpand
Higher yields and lower methane emissions with new rice cultivars
TLDR
It is shown in a series of experiments that high-yielding rice cultivars actually reduce CH4 emissions from typical paddy soils, and suggests that modern rice breeding strategies for high-Yielding cultivars can substantially mitigate paddy CH4 emission in China and other rice growing regions.

Rice genotypic variation in methane emission patterns under irrigated culture
Anthropogenic emission of methane under anaerobic condition of irrigated rice fields, is a global concern contributing to global warming more than any other greenhouse gases. A field experiment wasExpand
Metagenomics analysis of methane metabolisms in manure fertilized paddy soil
TLDR
Molecular variation in rice paddy is characterized by identifying key genes related to methane emission and methane oxidation, which may provide fundamental information regarding to mechanisms by which use of manure boosts methane emission from rice. Expand

TLDR
Data support the hypothesis that higher methane emissions observed in the tropical wet season as opposed to the dry season are associated with lower harvest index values resulting in excess carbon that could not be allocated to rice grain. Expand
Optimizing grain yields reduces CH4 emissions from rice paddy fields
TLDR
The observed relationship between reduced grain filling and CH4 emission provides opportunities to mitigate CH4 emissions by optimizing rice productivity. Expand
Methanogenic Pathway and Archaeal Communities in Three Different Anoxic Soils Amended with Rice Straw and Maize Straw
TLDR
The experiments showed that methanogenic degradation in different soils involved different meethanogenic population dynamics, and the path of CH4 production was hardly different between degradation of rice straw versus maize straw and was also similar for the different soil types. Expand
Response of a Rice Paddy Soil Methanogen to Syntrophic Growth as Revealed by Transcriptional Analyses
TLDR
It is proposed that Methanocella methanogens cope with low H2 and syntrophic growth by stabilizing the Mvh/Hdr/Fwd complex and activating formate-dependent methanogenesis. Expand

Abstract Water-saving practices for rice production has become one of the major agricultural policies in China due to the severe water scarcity. However, greenhouse gases emissions from paddy fieldExpand
Dynamics of the Methanogenic Archaeal Community during Plant Residue Decomposition in an Anoxic Rice Field Soil
TLDR
A highly dynamic structure of the methanogenic archaeal community was revealed during the decomposition of rice root and straw residues in anoxic rice field soil incubated at three temperatures, and the in situ concentration of acetate seems to be the key factor that regulates the shift of meethanogenic community. Expand
Methane fluxes show consistent temperature dependence across microbial to ecosystem scales
TLDR
Seasonal variations in CH4 emissions from a wide range of ecosystems exhibit an average temperature dependence similar to that of CH4 production derived from pure cultures of methanogens and anaerobic microbial communities, suggesting that global warming may have a large impact on the relative contributions of CO2 and CH4 to total greenhouse gas emissions from aquatic ecosystems, terrestrial wetlands and rice paddies.

Analyses of carbohydrate and oil fractions and gene expression profiling on a global scale in the rice waxy mutant GM077 revealed several candidate genes implicated in the carbon reallocation response to an amylose deficiency, including genes encoding AGPase and SUSIBA2-like. Expand
Methanogenic archaea are globally ubiquitous in aerated soils and become active under wet anoxic conditions
