Hydrologic variability governs GHG emissions in rice-based cropping systems of Eastern India.

Reducing methane (CH) emissions is increasingly recognized as an urgent greenhouse gas mitigation priority for avoiding ecosystem 'tipping points' that will accelerate global warming. Agricultural systems, namely ruminant livestock and rice cultivation are dominant sources of CH emissions. Efforts to reduce methane from rice typically focus on water management strategies that implicitly assume that irrigated rice systems are consistently flooded and that farmers exert a high level of control over the field water balance.

Dissecting genomic regions and underlying sheath blight resistance traits in rice ( L.) using a genome-wide association study.

The productivity of rice is greatly affected by the infection of the plant pathogenic fungus , which causes a significant grain yield reduction globally. There exist a limited number of rice accessions that are available to develop sheath blight resistance (ShB). Our objective was to identify a good source of the ShB resistance, understand the heritability, and trait interactions, and identify the genomic regions for ShB resistance traits by genome-wide association studies (GWAS).
