The default cyanobacterial linked genome: an interactive platform based on cyanobacterial linkage networks to assist functional genomics

A database of cyanobacterial linked genomes that can be accessed through an interactive platform (https://dfgm.ua.es/genetica/investigacion/cyanobacterial_genetics/Resources.html) was generated on the bases of conservation of gene neighborhood across 124 cyanobacterial species. It allows flexible generation of gene networks at different threshold values. The default cyanobacterial linked genome, whose global properties are analyzed here, connects most of the cyanobacterial core genes. The potential of the web tool is discussed in relation to other bioinformatics approaches based on guilty‐by‐association principles, with selected examples of networks illustrating its usefulness for genes found exclusively in cyanobacteria or in cyanobacteria and chloroplasts. We believe that this tool will provide useful predictions that are readily testable in Synechococcus elongatus PCC7942 and other model organisms performing oxygenic photosynthesis.
