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.

The gene sequences encoding disaggregatase
(Dag), the enzyme responsible for dispersion of cell aggregates
of Methanosarcina mazei to single cells, were determined
for three strains of M. mazei (S-6T, LYC and TMA). The
dag genes of the three strains were 3234 bp in length and had almost
the same sequences with 97% amino acid sequence identities.
Dagwas predicted to comprise 1077 amino acid residues
and to have a molecular mass of 120 kDa containing three repeats
of the DNRLRE domain in the C terminus, which is specific
to the genus Methanosarcina and may be responsible for
structural organization and cell wall function. Recombinant
Dag was overexpressed in Escherichia coli and preparations
of the expressed protein exhibited enzymatic activity. The
RT-PCR analysis showed that dagwas transcribed tomRNAin
M. mazei LYC and indicated that the gene was expressed in
vivo. This is the first time the gene involved in the morphological
change of Methanosarcina spp. from aggregate to single
cells has been identified.

Bacterial communities at different habitats in a Japanese paddy field ecosystem were compared to understand the bacterial world in the
ecosystem as a whole by analyzing data of the denaturing gradient gel electrophoresis (DGGE) band patterns and the sequenced DGGE
bands. The habitats were floodwater, percolating water, microcrustacean inhabiting in floodwater, plow layer soil, rice roots, rice straw
and rice straw compost incorporated in soil, rice straw placed on the soil surface, plant residues in paddy fields, and rice straw under
composting process. Phylotype (band) richness, diversity, evenness, and stability of the bacterial communities at the respective habitats
were evaluated based on the DGGE profile data. Phylotype richness was greater near plant residues, rice straw buried in soil and rice
straw placed on soil surface, while it was smaller at microcrustacean and rice straw compost buried in soil. The samples from plow layer
soil and rice straw compost buried in soil showed considerably higher index values for diversity, evenness, and stability, while those from
rice straw placed on soil surface and microcrustacean had lower values of the indices than other habitats. Sequences of totally 250 DGGE
bands were assigned to phyla or classes. Distribution of bacterial members to phylogenetic taxa was different among the respective
habitats. Inhabitants in plow layer soil were most widely distributed among the groups (nine phyla: Proteobacteria, Chloroflexi,
Chlorobi, Verrucomicrobia, Acidobacteria, Nitrospira, candidate division OP10, Cyanobacteria, and Actinobacteria), while those in
floodwater and microcrustacean were restricted to only three phyla (Proteobacteria, Bacteroidetes, and Actinobacteria). Proteobacteria
and Bacteroidetes were found at all the habitats and the habitats except for plow layer soil, respectively, whereas abundant members
belonged to Chloroflexi and Actinobacteria in plow layer soil. ``Comprehensive mapping'' of DGGE f

We investigated the relationships between dynamics of methanogenic archaeal communities and methanogenic activities in Japanese paddy ﬁeld soils by reverse transcription-PCR-denaturing gradient gel electrophoresis (RT-PCR-DGGE)and real-time PCR targeting 16S rRNA gene (16S rDNA)and 16S rRNA.The investigated paddy ﬁelds were managed on a double-cropping system,where rice was cultivated under ﬂooded conditions in summer and wheat was cropped after drainage in winter under drained conditions. Methanogenic archaeal 16S rRNAs were retrieved from all collected soil samples even under drained conditions by RT-PCR.DGGE band patterns from methanogenic archaeal 16S rRNAs were stable throughout the year and were similar to the patterns from their 16S rDNAs.The ratio of 16S rRNAs per one 16S rDNA fragment ﬂuctuated between 9.4 and 1.2 103 and increased during rice cultivations although contrary results were also obtained in some investigated plots.Methanogenic activities under ﬂooded conditions were higher than those under drained conditions. These results suggested that activities of methanogenic archaeal communities ﬂuctuated in a year depending on soil conditions.
