The composition and succession of methanogenic archaea in a Japanese paddy field were investigated
during an annual cycle by analyses of methyl-coenzyme M reductase a subunit (mcrA) genes and their
mRNA transcripts, which encode a key enzyme for methanogenesis. The paddy field was managed with
a double-cropping cultivation, i.e. rice grown in summer under a flooded condition and wheat cultivated
in winter under a drained condition. The mcrA genes and their transcripts were amplified from genomic
DNA and total RNA extracted from soil samples, respectively. Numbers of the mcrA genes estimated by
the most probable number-PCR showed little variation among the samples, whereas those of the transcripts
and the transcripts/mcrA gene ratios increased in the late period of the rice cultivation under
flooded condition. In addition, band patterns of denaturing gradient gel electrophoresis of the mcrA gene
PCR products were similar among the samples, while those from the transcripts were different between
the samples under flooded and drained conditions. Methanogenic activities of the paddy soils were
higher under flooded conditions than drained conditions. Clones belonging to Methanomicrobiales,
Methanosarcinales, Methanocellales (Rice cluster I), mrtA cluster (isoenzyme genes) and Methanobacteriaceae
were detected in the soils by the clone library analysis. However, the relative proportions
in the libraries from the transcripts were completely different, i.e. transcripts derived from members of
unidentified Methanosarcinales and Rice cluster I were predominantly detected in the soils under
flooded and drained conditions, respectively. These results suggested that distinct members in a wellestablished
methanogenic archaeal community transcribed mcrA genes and contributed to methane
production corresponding to soil conditions.
