Historically, they were used to define gene structure and gene regulation. Also the first genome to be sequenced was a bacteriophage. However, bacteriophage research did not lead the genomics revolution, which is clearly dominated by bacterial genomics. Only very recently has the study of bacteriophage genomes become prominent, thereby enabling researchers to understand the mechanisms underlying phage evolution. Bacteriophage genome sequences can be obtained through direct sequencing of isolated bacteriophages, but can also be derived as part of microbial genomes. Analysis of bacterial genomes has shown that a substantial amount of microbial DNA consists of prophage sequences and prophage-like elements. A detailed database mining of these sequences offers insights into the role of prophages in shaping the bacterial genome.<sup id="_ref-McGrath_0" class="reference">[9]</sup><hr /font></p>

<p><strong><span class="mw-headline"><font size="4">Cyanobacteria Genomics</font></span></strong></p><p><font size="3">At present there are 24 cyanobacteria for which a total genome sequence is available. 15 of these cyanobacteria come from the marine environment. These are six <em>Prochlorococcus</em><em>Synechococcus</em> strains, <em>Trichodesmium erythraeum</em> IMS101 and <em>Crocosphaera watsonii</em> [[WH8501. Several studies have demonstrated how these sequences could be used very successfully to infer important ecological and physiological characteristics of marine cyanobacteria. However, there are many more genome projects currently in progress, amongst those there are further <em>Prochlorococcus</em> and marine <em>Synechococcus</em> isolates, <em>Acaryochloris</em> and <em>Prochloron</em>, the N<sub>2</sub>-fixing filamentous cyanobacteria <em>Nodularia spumigena</em>, <em>Lyngbya aestuarii</em> and <em>Lyngbya majuscula</em>, as well as bacteriophages infecting marine cyanobaceria. Thus, the growing body Types of genome information can also be tapped in a more general way to address global problems by applying a comparative approach. Some new and exciting examples of progress in this field are the identification of genes for regulatory RNAs, insights into the evolutionary origin of photosynthesis, or estimation of the contribution of horizontal gene transfer to the genomes that have been analyzed.<sup id="_ref-Herrero_0" class="reference">[10]</sup></font></p><p><font size="4">[[Genome sequencing and genomics]]</font></p><p><span style="font-size: large"><strong><span class="mw-headline">See also</span></strong></span></p>
