16、visu- alization of T-RFs specifi c to phylogenetic groups (Fig. 1A). In conclusion, TRF-CUT is suitable for (i) T-RF prediction based on various enzymes to select enzymes with high phylogenetic resolutionand(ii)assigningT-RFsfromexperimental T-RFLP data to potentially corresponding sequences in the
17、database. As an example, we applied TRF-CUT to evaluate the com- munity structure of methanotrophic bacteria (MB) in a pH- neutral upland soil located near Go ttingen, Germany. MB play a crucial role in the global carbon cycle. The initial oxidation of methane to methanol is catalyzed by either a pa
18、rticulate meth- ane monooxygenase (pMMO) or a soluble methane monoox- ygenase. The membrane-bound form, pMMO, occurs in al- most all known MB and is homologous to the ammonium monooxygenase of ammonia-oxidizing bacteria. The pmoA gene encodes the catalytic center of pMMO and is widely used as a func
19、tional marker in environmental studies (4, 9, 10). Its application to study MB communities in a variety of methane- consuming upland soils indicated that two novel pmoA se- quence clusters, USC? and USC?, were dominant (7, 9).

However, in contrast
26、 to USC? and USC?, information on the distribution of this clus- ter is very limited. Community analyses of MB by T-RFLP have been per- formed mainly by MspI hydrolysis of 6-carboxyfl uorescein-la- beled pmoA PCR products (6), which were amplifi ed with the primers A189f and A682r (5). The applicati
27、on of this primer- enzyme combination as described by Horz et al. (6) to the Go ttingen forest soil sample resulted in four major peaks with one dominant T-RF of 80 bp (57%) (Fig. 1B). Application of TRF-CUT to a database including all public-domain pmoA and amoA sequences (June 2004) revealed that
28、the 80-bp T-RF was indicative for an environmental sequence from an upland soil (E33b-a, cluster I) and for Methylobacter sp. LW12. A 79-bp T-RF, which is experimentally diffi cult to distinguish from the 80-bp T-RF, corresponded to several taxa. Since the MspI hydrolysis did not resolve the MB comm
29、unity structure in this soil properly, we cloned PCR products and sequenced 13 environmental pmoA genes. Reconstruction of the gene phylogeny showed that the majority of sequences (11) were affi liated with cluster I sequences (Fig. 1A). Only two clones clustered with amoA genes (clone 25) and envir
30、onmental clus- ter II sequence E5FB-f (clone 10 9), respectively. The lack of clones affi liated with any other group of MB suggested a dom- inance of cluster I pmoA sequences in this pH-neutral temper- ate forest soil. On the basis of these fi ndings, we applied TRF-CUT to test various restriction
31、endonucleases in order to select one that allowed the discrimination of cluster I sequence types from all other pmoA and amoA genes. In silico digestion with HaeIII revealed a 199-bp fragment unique to the majority of cluster I sequences (Fig. 1A). For two cluster I sequences, TRF-CUT indicated equa
32、lly unique T-RFs of 140 and 316 bp, respec- tively. Subsequent T-RFLP analysis of pmoA amplifi ed from the soil DNA extract indeed showed a predominance of a 199-bp T-RF when HaeIII was used for digestion (87.0%), thus confi rming the predicted result. An additional 406-bp T-RF corresponded exclusiv
33、ely to the pseudo-T-RF of cluster I se- quences (3). Summing up the relative abundance of these two peaks, cluster I MB comprised 93.0% of the detected MB community. Peaks of the predicted sizes of 140 and 316 bp for cluster I, of 225 bp for cluster II, and of 45 bp for clones affi liated with ammon
34、ia-oxidizing bacteria were all relatively small (?1.0%) or undetected, indicating that organisms with these genotypes were only minor constituents of the meth- anotrophic guild in this forest soil. In summary, application of TRF-CUT prior to T-RFLP analysis revealed cluster I as the predominant MB i
35、n this pH-neutral methane-consuming soil and indicated that the dis- tribution of this novel gene cluster is more widespread than previously known. In this study, a clone library was necessary because of the limited availability of pmoA sequences from different habitats. However, with the prerequisi
36、te of an exten- sive data set, in silico predictions of multiple-enzyme digests should allow assignment of T-RFs to potentially corresponding organisms without extensive prior cloning efforts.
