Syntrophic microbiomes associated with methane suppressive irrigation in rice

Rice, a staple crop of half of the world’s population, is grown predominantly in flooded paddies which is one of the largest contributors to methane emissions. An effective approach is to minimise the anaerobic flooded conditions that favour the growth of methanogenic archaea. Our findings show that controlled irrigation can reduce methane emissions by up to 90%. In addition, methane levels stayed comparatively low in plots without rice plants. The microbial communities in empty plots were compositional similar to those observed in plots with rice cultivation. Methane is produced by the anaerobic decay of organic matter. Since methane is insoluble in water, it could escape from flooded paddies via the plant aerenchyma roots. The microbial soil dynamics under both aerobic and anaerobic conditions are still not well understood. In this study, both empirical methane measurements and microbiome profiles were presented under flood and drip irrigated conditions in an outdoor field in Singapor..., , # Syntrophic microbiomes associated with methane suppressive irrigation in rice Dataset DOI: [10.5061/dryad.vt4b8gv67](https://doi.org/10.5061/dryad.vt4b8gv67) ## Study Description This study aims to profile the methane levels and the soil microbiomes of Temasek rice (TR), Huanghuazhan (HHZ), IR64 rice varieties, and a control plot with no rice plants. The control plot is a negative blank control that provides information on the background soil microbiome and the levels of methane emissions without rice plants. All controlled irrigation trials were conducted in an outdoor rice field in Lim Chu Kang, Singapore. Rhizosphere soil samples were collected at one-month intervals during the early (2 July 2024), mid (13 August 2024), and late (10 September 2024) post-transplantation growth stages of rice for metagenomic sequencing.
