- •
Genome metagenomics revealed acetoclastic methanogenesis dominated in lowland rice.
- •
Genome metagenomics revealed serine pathway of methanotrophy dominated in rice.
- •
Methanobacterium, Methanosphaera, Methanothermus, Methanothermococcus were absent in a-CO2.
- •
Dissimilarity pathway of N metabolism dominated in lowland rice & more under e-CO2T.
- •
In e-CO2T 45, 20 & 35% higher CH4 emission, MBN and dehydrogenase activities were found.
