Synteny plot showing scytonemin and MAAs gene clusters with protein similarities referred to Chroococcidiopsis sp. CCMEE 057, taken as reference. Module 1 (in yellow) contains the genes for the biosynthesis of scytonemin monomers and dimers; Module 2 (in darkgreen) is responsible for aromatic amino acid substrates biosynthesis; Module 3 (in red) is made up of the genes for the export of scytonemin; Module 4 is responsible for response regulation to UV radiation; Cyanoexosortase module (in lightgreen) responsible for the export of scytonemin; MAAs module (in purple) containing MAAs biosynthetic genes; Shared Chroococcidiopsis genes (in pink) characterized by genes present in all investigated strains; Singleton genes module (in grey) containing genes present only in one species.-- FEMS Microbes

Comparative Genomics Of Space-resilient Chroococcidiopsis Cyanobacteria Reveals A Core Genetic Repertoire Supporting Extreme Tolerance Towards Desert And Non-Earth Conditions
