- Аннотация: Glutamate receptors (GluRs) are glutamate-controlled calcium channels involved in signaling processes in eukaryotic cells. In cyanobacteria, calcium signals are involved in the regulation of the heterocysts formation. Information on GluRs of cyanobacteria is very limited. The aim of the study was a phylogenetic analysis of the GluR of 17 species of cyanobacteria based on amino acid sequences selected according to the sequences of the homologous proteins of Synechocystis sp. PCC 6803 and Nostoc sp. PCC 7120. As a reference group, the gamma proteobacteria Pseudoalteromonas haloplanktis and Pseudomonas oleovorans, as well as the alpha proteobacteria Silicibacter sp. TrichCH4B were selected. The most significant result is the clustering of Silicibacter and P. haloplanktis together with cyanobacteria: in one cluster with Silicibacter, there are predominantly filamentous, heterocysts-forming cyanobacteria, suggesting the common origin of GluR in representatives of the genera Nostoc, Anabaena, Calothrix. The bacterium P. haloplanktis clustered together with a group of unicellular diazotrophic and non-diatrophic marine and freshwater cyanobacteria. The presence in the root of the GluR-tree of a single reference species - P. oleovorans, suggests that there were two horizontal transfers of genes encoding the GluR during evolution.The fact that GluRs of heterocyst-forming cyanobacteria form one cluster, allows us to hypothesize that this receptor can be involved in regulation of heterocyst differentiation. An experimental verification of this hypothesis is planned in ours future experiments. The work is supported by RFBR grant No. 17-04-00412.
