Figure 7

The origin of the CRY/PL members. (I) All three photolyases 6-4, CPDII and CPDI/III are found in all three domains of Eukaryota, Bacteria and Archaea. (II) DASH-CRY is mainly found in Eukaryota and in Bacteria. However, one archaeon is known to have DASH-CRY as well. (III) In eukaryotes, the PCRY-like protein arose next. It is found in all kingdoms except fungi. We assume that it has been lost in the fungi studied. (IV) Origin of PCRY and PPL in some algae and in Viridiplantae. (V) Origin of MCRY, which occurs in both Cnidaria and Bilateria. Its origin is therefore attributed to planulozoans. (VI) Origin of ACRY in certain cnidarians. (VII) Origin of DCRY, which occurs only in Bilateria, but in both Deuterostomia and Protostomia. (VIII) Origin of CRY4 in some chordates. The number of organisms tested is shown in parentheses next to the taxonomy name. The archaeon Halorhabdus utahensis and the hemichordate Ptychodera flava (both marked with *) were investigated in the studies by Mei and Dvornyk (2015) [19] and Kotwica-Rolinska et al. (2021) [43].
