DNA repair mechanisms in algae

OpenAlex · Türkçe

DNA repair mechanisms have been a remarkable subject in algae, as in every living organism. Continuous exposure to mutagens has led to the evolution of protection mechanisms in primary producer algae of aquatic ecosystems and various pathways have developed in multiple algae. These pathways are direct and indirect. Undoubtedly, the most studied pathway is photoreactivation and photolyase enzyme. Photoreactivation is a repair mechanism that recycles thymine dimers by occuring UV radiation in both prokaryotic and eukaryotic organisms. Apart from this, there are limited findings in algae regarding O6 methyl guanine repair, another direct pathway. Mismatch repair, one of the indirect pathways, contains homologs of well-defined Echerichia coli enzymes in algae. In addition, homologs of enzymes belonging to base excision repair and nucleotide excision repair mechanisms defined in higher eukaryotes have been investigated in various algae, especially in Chlamydomonas sp. Recombinational repair is one of the indirect repair types seen in algae. In this study, a general overview of the repair mechanisms found in algae were presented.
