ABSTRACT: In silico analysis can be useful to infer about the horizontal gene transfer (HGT) as well as to deduce about the evolutionary relations of catabolic genes. In this study, we performed the analysis of two housekeeping genes (fabD and rpoD) and two catabolic genes (alkB and catA) from 12 bacterial genus usually founded in marine environments. Comparing the trees obtained from Bayesian Inference hypotheses of these genes with 16S rDNA sequences, we noted the topologies are different among housekeeping or catabolic genes trees comparing to 16S gene tree. The HGT may be used with the purpose to spread genes within bacterial community according to environmental conditions in marine ecosystems. In this way, using our analysis, we concluded that hydrocarbons catabolism genes as well as housekeeping genes can be subject to horizontal gene transfers among marine bacterial communities.
