Web6 sep. 2024 · Chen et al. ( 2024) found that a stronger root system could transport more oxygen into the soil and contribute to CH 4 oxidation by methanotrophs in paddy fields. However, a larger root weight provides more organic materials as substrates for CH 4 production, which increases CH 4 emission in paddy fields (Kerdchoechuen 2005; Wang … Web1 feb. 2024 · The wild-type (WT) and the mutants were grown in paddy (flooded), non-paddy and hydroponic system to assess phenotypic traits including O2 diffusion, GHG emission and aerenchyma formation. The mutants exhibited significant reductions in several morphophysiological traits including 20–60% aerenchyma formation at various distances …
